I found a thing comparable to the present concrete (?oating) from the ?oor (Yuka) and the wall (wallpaper) after the house excavated at the aftermath of Israel and Galilee region. In the ruins (Ichiki), there were ?oors and walls made by combining the stone and water that crushed limestone into the cement made from limestone (squid). ====>> All Companies Cement Price list in India Cement is one of the ingredients for making concrete. Concrete is made by mixing water, aggregate (sand (sand), gravel, etc.) etc. into cement. There seem to be many people who think that cement and concrete are the same things, but cement is like a glue (so-called glue). The ancient Egyptian pyramid four thousand years ago is piled up stones, but cement-like things are used to stick the stones. This is di?erent from the concrete of iftaf mixed with water, it is mixed with sand and mud etc in volcanic ash (bamboo shoots) with lime and burner without using water I have it. Cement has been used for human life for a long time. Limestone is a rock made from coral and shell?sh deposited on the bottom of the ocean. There are cases where fossils are included. The main raw material of cement is limestone. Most of the limestone is produced in Japan, so you do not need to rely on imports (Yunu). From Hokkaido to Okinawa (Okinawa), you can dig out limestone from mountains throughout the country. Before the cement called “clinker “ is ?nely crushed (mixed) with limestone to clay (neel), silicone, iron oxide (sakutetsu) etc and mixed together I will make a product in between. Add a gypsy to that “clinker” and crush it further and ?nish it into cement. https://medium.com/@modicaredpoint/history-of-cement-5db548939b0f 1/3

In recent years, instead of clay, after removing iron from iron ore (iron ore) at the iron ash (yes) coal burned (also) at the thermal power plant We accept construction waste generated from construction sites (Kensetsu Kenba), save natural resources and save a lot of energy (environment) . Clinker burns raw materials with a bite, then quench and become a black lump (mass). When water is added to the cement and kneaded well, at ?rst it becomes like clay (Nendo), it will become hard as time passes. Because it is dry, it does not solidify but it solidi?es by reacting with water. That is, it is a chemical reaction between water and cement (Kagaku Hanon). This chemical reaction is called “hydration reaction”. It is said that when a chemical reaction occurs in general (the most), it is said to emit heat, but it also generates heat when cement reacts with water. This heat is called “the heat of hydration of cement” (Sumenetsu). Cement becomes like clay at ?rst by adding water, it hardens while emitting heat, and then the mass becomes solid. The chemical reaction continues during that time. It is said that all reactions will take 70 to 80 years to complete. Sumitomo Osaka Cement people taught that “cement is alive”. Cement is strange. https://medium.com/@modicaredpoint/history-of-cement-5db548939b0f 2/3
