Q1 Why is desert sand not used for construction?
KR It is a good Q and A; however,”
Desert sand isn’t useless, but it does have limitations, especially for
certain construction applications. Here’s a clearer breakdown:
Concrete Production: While it can be used, desert sand often requires
blending with other materials to achieve the right properties for concrete.
Its rounded grains may not bond as well as angular aggregates.
Landscaping: Desert sand can be great for landscaping projects, including
creating pathways or decorative features. It’s often used in xeriscaping
(water-efficient landscaping).
Soil Improvement: It can improve drainage in heavy clay soils when mixed
appropriately.
Sandblasting and Filtration: Desert sand can be used in sandblasting
applications and water filtration systems, depending on its purity and
grain size.
Alternative Uses: Beyond construction, it can be used in arts, crafts, and
certain industrial processes.
In short, while it may not be the best choice for concrete, desert sand has
various applications where it can be effective.
Yes, there are several innovative approaches to make desert sand more
suitable for construction. Here are a few modalities:
Grading and Blending: By mixing desert sand with other aggregates (like
crushed stone or gravel), it can enhance the overall properties of the
concrete or mortar. This can improve compaction and bonding.
Additives: Using chemical additives or polymers can help improve the
workability and strength of concrete made with desert sand. These additives
can enhance the bonding properties and mitigate some of the sand's
limitations.
Stabilization Techniques: Techniques such as soil stabilization (using
cement, lime, or other binders) can help improve the structural integrity
of desert sand, making it more viable for use in construction.
3D Printing: Emerging technologies like 3D printing are being explored to
utilize desert sand in constructing buildings, where the sand can be mixed
with binders to create durable structures.
Engineered Sand: Some researchers are experimenting with processes to crush
and reshape desert sand to make it more angular, improving its suitability
for concrete.
Sustainable Alternatives: Using desert sand in eco-friendly construction
methods, such as rammed earth or sandbag construction, can also be a viable
option.
These methods are increasingly being explored as the demand for sustainable
building materials grows.
M sand, or manufactured sand, is a construction material
produced by crushing rocks and stones. It is designed to serve as a
substitute for natural sand, often used in concrete and other construction
applications. Here are some key points about M sand:
Production Process: M sand is created through a process of crushing,
screening, and washing to ensure uniformity and the right particle size.
This helps to eliminate impurities and unwanted materials.
Particle Shape: Unlike natural sand, which is often rounded due to natural
weathering, M sand typically has a more angular shape, which can enhance
its binding properties in concrete.
Quality Control: M sand can be produced to specific grading requirements,
ensuring consistency in quality. This is an advantage over natural sand,
which can vary significantly in composition and quality.
Environmental Impact: Using M sand helps reduce the depletion of natural
sand resources, which is becoming a significant environmental concern in
many regions.
Applications: M sand is commonly used in concrete production, plastering,
and various other construction activities.
Overall, M sand is a reliable alternative to natural sand, especially in
areas facing sand shortages or where sustainable practices are prioritized.

Q2 What is classy in America but trashy in India?
KR: are they joking? Hearsay facts?
1 yellow pea:
In India, yellow peas are widely used and valued for several applications,
reflecting both culinary traditions and agricultural practices. Here are
some key uses:
Culinary Uses: Yellow peas are commonly used in traditional Indian dishes,
such as dal (lentil soup) and various curries. They can be cooked whole,
split, or ground into flour.
Split Peas: Split yellow peas are popular for making khichdi, a comfort
food made with rice and lentils. They are also used in various snacks and
preparations.
Flour Production: Yellow pea flour, known as besan, is utilized in making
batter for snacks like pakoras and dosa, as well as in sweets and other
dishes.
Protein Source: Given their high protein content, yellow peas are
increasingly recognized as a valuable source of plant-based protein,
particularly in vegetarian and vegan diets.
Animal Feed: Similar to the U.S., yellow peas are used as feed for
livestock, contributing to the protein requirements of animals.
Sustainable Agriculture: Yellow peas are often grown as a rotational crop,
improving soil fertility by fixing nitrogen and reducing the need for
chemical fertilizers.
Export: India is also a significant exporter of yellow peas to various
countries, catering to global demand for legumes and pulses.
The diverse uses of yellow peas in India make them an important crop both
nutritionally and economically.

Charcoal stove: It looks somewhat like this:
KR USA uses them only outdoors as done in Punjab dhaba. “India
Traditional Cooking: Charcoal stoves are used in some rural areas and among
certain communities for traditional cooking, especially where other fuel
sources are limited.
Tandoors: Charcoal is often used in clay tandoors, which are traditional
ovens for baking bread (like naan) and cooking meats. This method is
popular in both homes and restaurants. {USA use only like this}
Affordability: In some regions, charcoal is a more affordable fuel option
compared to gas or electric stoves, making it a practical choice for many
households.
Health Considerations: While widely used, there are concerns about health
and environmental impacts due to smoke and emissions from charcoal cooking.
xxxxxxxxxxxxxxxxxxxxxxxxxx
Indian broom: This looks like this:
USA
Material: In the USA, brooms are often made from synthetic materials or
bristles. Traditional straw brooms are less common, although they can still
be found in some markets.
Usage: Brooms in the USA are used primarily for cleaning indoor spaces,
such as homes and commercial buildings. They may not have the same cultural
significance as in India.
Variety: There is a wide range of brooms available, including push brooms,
dustpans, and specialty brooms designed for specific surfaces (like tile or
hardwood).
Market Availability: Brooms are readily available in supermarkets and home
improvement stores, often as part of a broader selection of cleaning tools.
In summary, while Indian broomsticks are integral to daily life and
culture, emphasizing traditional materials and practices, in the USA,
brooms are more utilitarian, focusing on efficiency and convenience with a
wider range of materials and styles. So, I do not think any american is
swayed by the Indian broomstick.

Candle light dinner and hurricane lanterns: Again the lanterns are used as
a decorartive pieces in any part of the world as we keep a Veena in the
show-case.
-------------------------------------------
Leaf plates:
KR In the U.S., plantain leaves are not as commonly used in everyday
cooking, but they do appear in certain cuisines, especially in areas with a
significant Latin American or Caribbean influence. For example, they might
be used in dishes like tamales or to wrap food for grilling. While not a
staple for most American households, those familiar with these culinary
traditions often incorporate them into their cooking

Q3 Was anyone 1,000 years ago as smart as someone with average
intelligence today?
KR Mr Gopalakrishnan insulted all of us. Even in
Kerala, weathermen aplenty in the agri sector who can predict the natuire;
by the pattern of ants’ swarms, people can say the weather to arise.
Australian larant it too late.

Q1 Why is desert sand not used for construction?
A1 Li Ming, Studied at Luoyang Institute of Science and Technology
(Graduated 2012)Aug 26
There is a high demand for sand globally and it is widely used in many
industries, especially construction. Since deserts are full of sand, it is
easy to mistake sand for an almost inexhaustible resource. However, why
can't desert sand replace river sand and artificial sand as a building
material despite its abundance?
1. Severe weathering
Desert sand is mainly formed by wind. In arid areas, stones slowly crumble
under the effect of weathering, with larger stones remaining in place to
form landforms such as the Gobi and smaller stone particles piling up under
the effect of wind to form deserts.
Desert sand is mostly stone weathering, after years of wind and rain
erosion, become sparse and scattered, no sticky.
2. The fineness is too small
Construction sand particle size is basically more than 1mm, the need for
different particle size sand in order to achieve the grading requirements,
the desert sand is wind transport, deposition and become, the particle size
is much smaller (generally below 0.25mm), the particle size is too fine.
3. Poor plasticity
The cross-section of construction sand particles are generally round, so
that the force is more uniform, and the sand at the bottom of the river is
carried by the river, the particles roll along the river, the sand selected
is more rounded, while the desert sand is smooth and has a certain degree
of oily, does not have the plasticity of ordinary construction sand.
4. High alkali content
Desert sand is formed by long-term weathering under the dry environment of
wind and sunshine, with high alkali content, which will react with some
substances in the building materials, affecting the quality of the sand and
gravel mixture, thus affecting the strength and safety of the building.
5. Low rating
Desert sand is mostly weathered in situ, not transported over long
distances and sorted, various grain sizes are mixed with each other, and
the grading is not suitable for use as building sand.
6. Impurity
Construction sand requires high mud content, desert sand impurities in the
unfiltered, high clay content, if used for concrete, concrete strength will
be greatly reduced. River sand, on the other hand, is washed and deposited
by water currents from a long distance, and after a long time of washing
and flushing, sea sand becomes very clean.
7. High transport and mining costs
Deserts are usually far away from cities, and considering transport costs
and labour prices, desert sand is not cheap.
Q2 What is classy in America but trashy in India?

Yellow peas: These are called ‘Bathani’ in Hindi and Telugu. They look like
this: (they are roasted ).
We had been to a big grocery store in US. There we saw a packet of these
peas about 100 grams.
The packet itself was really impressive indicating all the nutritional
values.
As usual I saw the price. It was 2 or 3 dollars.
“They are very precious items here. Those who opt for low carbohydrate
diet will go for them. They are sold as soon as they arrive in the stores”
my son explained.
And here in India they are called “time pass bathani”, indicating they are
consumed only to pass the time.
They are mostly available in railway stations, beaches, parks etc. And
considered as poor man’s snacks.
How ironical it is that US people search for Healthy Indian food items
while we think that eating Pizzas and burgers is classy.
Charcoal stove: It looks somewhat like this:
My mother used to use this when we were kids. Now it is used in remote
villages (though I am not sure).
A charcoal stove with one pound of charcoal costs some twenty dollars (I
think we saw this in Ikea store).
“This is considered one of the classy items here. They use it for outdoor
cooking on weekends” son explained.
Though I don’t use it now, I should admit that smoked items like ‘baigan ka
bartha’(smoked brinjal) taste great when smoked on charcoal stoves than on
gas stoves.
Indian broom: This looks like this:
It was priced some 4-5 dollars. In India now they are replaced by synthetic
brooms.
“Wow! Cute! Beautiful!” were some exclamations made by a young US couple
after seeing those brooms.
“They sweep best where there is no carpet” the couple said to each other
with a twinkle in their eyes.
My note- Quality sturdy and lengthy Coconut brooms are dearer and costly in
Tambaram corporation area also. A quality broom costs anything above
70-00. Less lengthy but strength medium brooms are used by construction
workers and cleaning people. Normal brooms cost above 50-00.
Candle light dinner and hurricane lanterns: We only do when there is a
power cut. But in US it is classy. They decorate out doors with ‘Hurricane
lanterns’(though electric bulbs are used in them). In India we find them
lying on attics.
Leaf plates: In India leaf plates are replaced by thermocol plates in
parties and in US they are shifting to leaf plates.
Earth is round. Items from east are going west and vice versa. Few decades
from now, scene may again reverse. Who knows!
Edit: Some more items are added after reading the comments. Thanks to
Nagabhushan Somraj and Pankaj Gangwar.
Q3 Was anyone 1,000 years ago as smart as someone with average
intelligence today?
A3 Nancy James, Updated Aug 10
I was teaching a science class in the Australian desert and the class was
quietly working (it was a nice class). I looked out the window and I
commented to no one in particular, “Looks like there will be a cyclone next
week.”
The students mostly started laughing and one piped up “The national
meteorologists said that the low would pass by without any problem.”
But there was a part of the class that did not object to my announcement…
the local indigenous people. Instead they asked, “How do you [of European
descent] know what our elders know?”
I smiled and pointed out the window, “The wind has changed to go in the
opposite direction, the clouds have moved north instead of south, and the
corellas (a small cockatoo) have all left town and gone to shelter in
Karijini (local mountain range).”
The indigenous students were impressed and everyone else thought I was an
idiot… at least they did until the cyclone hit the next week and flooded
all the roads out of town.
The lesson here is that intelligence is not about knowledge gained through
complex technology such as that used by meteorologists. Satellites,
pressure gauges, wind charts—all of that is just data. True intelligence
comes from an ability to assess the data and make a reasonable
determination.
I made a reasonable determination based upon observational data ... data
indigenous people had been using for 50,000 years with success.
Ancient peoples used their intelligence to determine weather patterns,
judge hunting techniques, and plan for the future year. They did all this
without satellites or computers. Are modern people more intelligent than
those before them?
No, we are not.
Ancient peoples can hold their head high … for they are intelligent and
wise. Only an idiot would think otherwise.
Q4 Can you share a funny story or anecdote that never fails to make
you laugh?
A4 Robert Farnsworth,13h
A woman walking along a beach discovered a bottle. She took the cork off to
see inside, and out popped a magic genie.
“You have freed me,” said the genie, “and I have the power to grant you
three wishes.”
“Wow,” said the woman, “this is really my lucky day.”
“So what would you wish?”
She thought for a moment.
“First, I want to be able to have unlimited money for whatever I want or
need.”
“Granted” said the genie, “you say the word, money will appear.”
“Second, I want my little house transformed into a castle, with beautiful
rooms, a pool, and a beautiful kitchen and romantic bedroom.”
“I can do that,” said the genie, “your wish is my command.”
“Third, my greatest love and companion has been my cat Sir Charles, I want
him to be transformed into a wonderful, romantic prince … the man of my
dreams.”
“Done!” said the genie.
And the genie said to her, “Thank you for freeing me. Your wishes are
complete, Live well! Your prince is waiting for you in your new castle.”
She ran to the castle. Standing on the front porch was the most handsome
prince she could imagine. He ran up to her.
He grabbed her, gave her a big hug, a wonderful kiss, and then gently
whispered in her ear, “Now, aren’t you sorry you had me fixed?”
Q5 Can you tell a touching story?
A5 Hamid, Sep 11
An old man entered the court so that he could complain about his son. The
judge asked, what is your complaint against your son.
The old father said, I want to ask my son for monthly expenses according to
his status.
The judge said, that is your right, what is the need for a hearing on this.
Your son should give you the money every month. The father said that I have
no shortage of money, but still I want to take the money from my son every
month, even if it is less. The judge was surprised and said to the father, you
are so rich, then why do you need money from your son?
The father gave his son's name and address to the judge and said that if
you call my son to the court, you will know a lot of things. When the son
came to the court, the judge told him that your father wants to take
monthly expenses from you, even if it is less. The son was also surprised
to hear the judge's words. He said that my father is very rich, what is the
need for money for him?
The judge said, this is your father's demand. The father said, Judge sir,
tell my son that he will give me 100 rupees every month and that too with
his own hands and there will be no delay in paying the money.
The judge said to the old man's son, that you will give Rs. 100 every month
to your father without any delay, this is the court order to you.
After the trial was over, the judge called the old man and asked, if you
don't mind, may I ask you one thing, why did you file this case against
your son, you are a very rich man and this is such a small price.
The old man cried and said, Judge Sir, I was longing to see my son's face.
He is so busy with his work that a long time has passed, I have not met
him, and neither have I talked to him face to face nor on the phone. I love
my son very much. That is why I filed this case against him, so that every
month I will be happy to meet and see him. Hearing this, tears came in the
eyes of the judge too.
The judge told the old man that if he had told me earlier, he would have
punished him for ignoring and not taking care.
The old father looked at the judge with a smile and said, "If you had
punished him, it would have been a matter of sorrow for me, because I
really love him very much, and I would never want my son to be punished or
suffer because of me."
