What is the chemical reaction occur in cement?
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 + 173.6kJTricalcium silicate + Water--->Calcium silicate hydrate+Calcium hydroxide + heat2 Ca2SiO4 + 5 H2O---> 3 CaO.2SiO2.4H2O + Ca(OH)2 + 58.6 kJDicalcium silicate + Water--->Calcium silicate hydrate + Calcium hydroxide +heat
What is builders use in inorganic chemical?
cement is made up of four main compounds: tricalcium silicate (3CaO × SiO2), dicalcium silicate (2CaO × SiO2), tricalcium aluminate (3CaO × Al2O3), and a tetra-calcium aluminoferrite (4CaO × Al2O3Fe2O3) hence builders use inorganic chemicals
Is lithium a silicate or non silicate mineral?
Non-silicate.
Is ice a silicate or a non-silicate mineral?
It is a nonsilicate mineral. It is an oxide.
Is cinnabar silicate or non silicate?
Cinnabar is a non-silicate. It is mercury(II) sulfide HgS.
DOES silicate cement release fluoride?
Silicate cements contains and release fluoride.
What is purpose of tricalcium silicate in cement?
Tricalcium silicate is the main mineral responsible for strength development in the hydration of portland cement. Portland cement contains 50 to 70 percent C3S (Tricalcium aluminate) It is also known as alite. To keep it simple, C3S reacts with water to form calcium silicate hydrate (CSH) and a byproduct, calicum hydroxide. CSH is what gives concrete its strength and binds the aggregates together.
Can you use silicate cement as a permanent restoration?
yes
What is the Chemical composition of Cement including C3S and C2S?
c3s is tricalcium silicate and c2s is dicalcium silicate

Composition of cement?
Cement is made , not found. Portland cement, for instance, is made by heating limestone and clay to high temperature (1500 degrees Celsius) and crushing the result to a powder for sale.
What are the contents in cementitious waterproofing chemicals?
Alkaline Sodium Silicate mixed with cement
Which metallic oxide is major constituent of cement?
Hydrated cement produces CaO. So calcium oxide is a major constituent. Silicon dioxide is also produced resulting in calcium silicate.
What are the major components of cement?
The major components of cement are,Bogue's componentsTricalcium silicate or alite - C3SDicalcium silicate or belite - C2STricalcium aluminate or celite - C3ATetracalciumaluminoferrite or felite - C4AF
What is the purpose of cement in concrete?
cement is the binder for concrete like glue with out it you have mud with rocks
What is the use of fly ash in civil engineering?
it is a waste product from steel industry and has properties similarly to that of cement .it mainly consist of calcium silicate.
What can you add to Portland cement to make it sulphate resistant?
The sulphate resistant cement is made with low C3A content is found to be effective.Such cement with low C3A and comparitively low C4AF content is known as sulphate resisting cement.This cement has a high silicate content.The specification generally limits the C3A content to 5 percent.
