Earthquake-proof concrete

Construction company Kajima (Japan) has successfully researched and manufactured " flexible concrete " that can withstand earthquakes. It is currently used in many high-rise buildings in Japan to combat seismic attacks. This type of concrete contains polymers thickened by human hair, often used in tires, woven together to prevent cracks spreading in concrete.

Instead of being bent and able to fall on one side with a high impact force after a crack like normal concrete, this concrete will make the building stronger if it is vibrated by earthquakes and still usually if there is an earthquake with great intensity.

Kajima company has spent 10 years researching " flexible concrete " and the product was introduced in 2003, but so far this type of concrete only accounts for 0.1% of the Japanese concrete market, partly due to the price Its height is 10 times that of ordinary concrete.

Japan is a country frequently hit by earthquakes, accounting for 20% of earthquakes with magnitudes greater than 6 Richter levels in the world.

The earthquake in Kobe (Japan) killed 6,400 people.The country's construction companies are working hard to research building materials that can withstand earthquakes to reduce human and property damage (Photo: Washington.edu).
