Cement is the mixture of tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite and gypsum. Cement is mixed with water, the silicates and aluminates in the cement undergo a chemical reaction, the resulting hardened mass is formed.
2 Ca3SiO5 + 7 H2O ---> 3 CaO.2SiO2.4H2O + 3 Ca(OH)2 + 173.6kJ
Tricalcium silicate + Water--->Calcium silicate hydrate+Calcium hydroxide + heat
2 Ca2SiO4 + 5 H2O---> 3 CaO.2SiO2.4H2O + Ca(OH)2 + 58.6 kJ
Dicalcium silicate + Water--->Calcium silicate hydrate + Calcium hydroxide +heat
What else can I help you with?
What changes the rate of a chemical reaction or allows a chemical reaction to occur?
Heat?
Why is a chemical reaction in cement so important to concrete?
to make it strong
How does the evolution of gas occur in a chemical reaction give an example?
This is a sign of a chemical reaction.
Would a chemical reaction occur if calcium is added to magnesium chloride?
Any reaction occur.
Can alcohol and sharpie cause a chemical reaction?
Any reaction occur.
Is making cement a chemical reaction?
yes
What comes out of a reaction?
Chemical changes occur after a chemical reaction.
Is cement recyclable?
No, cement is not recyclable.Because when it is mixed with water chemical reaction takes place and gains strength and hardens.The hardened cement cannot be used as a recycled one because no chemical reaction takes place when mixed with water.

Where does a chemical reaction in a plant occur?
In the chemical installations of the plant.
Will a chemical reaction occur if a chlorine gas is dipped in a solution of potassium iodide?
no is not a chemical reaction
Can alcohol and sharpie cause a chemical reaction?
Any reaction occur.
What does a catalyst reduce to a chemical reaction?
Adding a catalyst a chemical reaction can occur with a lower activation energy.
What is the reaction of cement with hydrochloric acid?
When cement reacts with hydrochloric acid, a chemical reaction occurs in which the calcium compounds in the cement are dissolved. This reaction results in the formation of calcium chloride, water, and carbon dioxide gas. The dissolving of the calcium compounds weakens the cement structure and can lead to its deterioration.
