Lord Shri Ram’s army had built a bridge over the sea to climb Lanka. from floating stones. But is it possible today that no stone is immersed in water at all? It is possible sir! Just read this story.
German scientists have invented such a technique, due to which even stones start floating.
“Nath Neel Nal Kapi Dwa Bhai, Larikai Rishi Ashish Pai / Tinh Ke Paras Kiye Giri Bhare, Tarihhin Jaldhi Pratap Tumhare.” In this chaupai of Ramcharit Manas, the ocean says to Lord Shriram, “O Nath! Neel and Nal are two monkey brothers. He had received blessings from a sage in his childhood. By touching both of them, even heavy stones will float on the sea due to your majesty.
so like this construction of ramsetu In Nal and Neel showed their engineering. Lord Shriram’s name was written on the stones and they were thrown into the sea. According to legends, Ramsetu was prepared with floating stones in this way, through which Shriram climbed Lanka and freed his wife Sita after killing Ravana.
Well, what happened in Tretayuga, is it possible now? Can it happen in today’s time that a stone can float in the ocean? Your answer may be no, but in Germany scientists has made this a reality.
Scientists have made such a stone which does not sink in water. He can swim in water. These scientists have named it infrared concrete. Experts are constantly doing research on this. They claim that in the coming times it is going to be very useful for human life.
How does a stone float in water?
To make concrete float in water, small balls of soil filled with air are mixed in it, due to which the weight of concrete becomes light. This can also happen with glass bullets. material scientist Karl Christian Teinel According to it, first it is made from clay balls, then these clay balls are mixed with cement, the material prepared from this, weighs a quarter of that of normal concrete.
The more air, the better the material
According to materials scientist Karl Christiansen, the more air in concrete, the stronger the material will be. The more air there is in this infrared light, the better it will float in water, currently Karl’s team is examining the technology of this concrete at the University of General Federal Armed Forces.
can build a wall
Material scientist Nancy Boettner told that a wall can be made from this infralite concrete. Due to air in it, it gives excellent insulin. Due to having holes in it, it absorbs carbon dioxide, which makes it stronger by chemical changes in concrete with the help of calcium hydrochloride already present in concrete. Due to being rough, this concrete also absorbs green house gases. Which converts it into calcium carbonate in a few years. This also gives strength to the wall.
How strong?
Floating concrete weighs a quarter of the weight of normal concrete, but has a strong strength, when viewed with a scanning electron microscope, it shows that it has sharp structures inside, giving it strength. However, its ability to withstand pressure is less. According to materials scientist Nancy Boettner, during the research, it was found that normal concrete can withstand high pressure of at least 60 tons, at higher pressure it bursts, while infrared technology can withstand only 9 tons of pressure.
Will be useful in building a house, but…
According to scientists, this infrared technology can be used in common houses, the walls made from it will be very strong. However, due to not being able to withstand high pressure, it cannot be used in earthquake-prone areas. Apart from this, it can be dangerous to use this concrete even in high rise buildings.
