Tricalcium silicate(C3S) ALITE (gives early strength to cement....heat of hydration is 120 cal/gm)
Dicalcium silicate(C2S) BELITE (gives later strength ie after 7 days...less heat of hydration)
Tricalcium aluminate(C3A) CELITE (gives INITIAL strength...high heat of hydration ...320 cal/g)
Tetracalcium alumino ferrite(C4AF), FELITE (very high heat of hydration)

Calcium is a reactive metal whose compounds make up limestone. It forms calcium carbonate, which is the main component of limestone and other minerals like marble.
As Calcium Has been used for Building Purpose And For the Similar purpose it is Using IN Cement Which Depend upon its Bonding Property.It Actually react with Water in the Presence of Sesqui oxide(oxygen with Cation in (3:2) ratio) and form a Complex Compound With water of Crystalline Which have A power to hold the Material and So called cement.
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
You can lay cement in cold weathers as long as it isn't raining.
They are termed organic compounds. Compounds containing only carbon and hydrogen are called hydrocarbons and they are a subset of organic compounds.
1. What are the causes of unsoundness of cement?
Concrete is a mixture because it is composed of different materials, such as cement, water, aggregates (like sand and gravel), and sometimes additives. These components are combined in specific proportions to create a strong and durable building material with desired properties like strength, durability, and workability. Mixing these materials together allows for a uniform distribution, ensuring consistent quality in the final product.
