Answer 2

Bogues Compounds: When water is added to cement it react with the ingredients of the cement chemically & results in the formation of complex chemical compounds terms as BOGUES compounds. which are not for simultaneously. Content increase for the pre fabricated concrete construction, Cold weathering construction.

(OR)

In simple, we can say that Bogues compounds are the complex compound formed during the hydration of cement.These calculations are explained by a system developed by R.H.Bogue.

When water is mixed with cement, the hydration process begins.The ingredients in concrete react each other with the help of water and forms more complex compounds.These compounds are called Bogues compounds.

process begins. Each Compound has its own property.The property of cement can be changed by varying the percentage of these compounds during hydration of cement.

Types of bogues compounds :

1. Tri-Calcium Silicate (C3S)

Tricalcium silicate promotes cement to hydrate quickly and makes more strength at early stages.

Tricalcium silicate have a high heat of hydration eg-Rapid Hardening cement

2. Di-Calcium Silicate

Dicalcium silicate strengthens the concrete from 7 days to 1 year.

They have less heat of hydration eg: Low heat cement

3. Tri-Calcium Aluminate

Tricalcium aluminate has a small contribution to the strength of first 24 hours and they have a high heat of hydration.

4. Tetra Calcium Alumino Ferrate
