cement production line chemical reaction

Chemical Reactions Involved in the Manufacture of Cement Following chemical reactions take place during the manufacture of cement 1 First of all limestone decomposes into lime after getting heated to a high temperature 2 The lime produced in first reaction reacts with silicon dioxide to produce dicalcium silicate 3 Lime also reacts with silicon dioxide to produce one more compound tricalcium silicate 4
