What is the chemical formula of concrete?

Answer 1

The chemical formula of concrete is not a simple formula like that of a compound, as concrete is a mixture of various materials. However, the primary components of concrete are cement, water, aggregates (such as sand and gravel), and sometimes additives or admixtures. The chemical formula for cement, which is a key ingredient in concrete, is typically Ca3SiO5, Ca2SiO4, Ca3Al2O6, and Ca3Fe2O6.

Answer 2

There are actually a couple of different equations- there is more than one chemical reaction taking place at the same time. One gives "early" strength to concrete, one gives "late" strength.

See the link below, especially the section on Hydration.

Answer 3

I dont think there is an exact chemical formula for concrete itself. Firstly there are so many different types of concrete that can be made, it would be hard to give a blanket chemical formula for all of them. concrete is comprised of Cement, Sand, Stone and water with an occasional chemical admixture depending on the specified use or location of the mix. If you really wanted to I suppose one could take all of the chemical formulas for each component in a specific mix, and MASH it all together. That would give you a formula for a specific batch. Hope this helps

Answer 4

The chemical formula for concrete is typically represented as CaO·SiO2·H2O, which represents the major components of calcium oxide (CaO), silica (SiO2), and water (H2O) present in concrete mixtures. Additional components such as aggregates, additives, and admixtures may also be included in concrete compositions.

Answer 5

Cement is not a chemical compound - it is mixture

Answer 6

Concrete is not a chemical compound. It is a mixture which includes calcium silicates.
