CEMENTING - cu

The effect they have on properties of the cement have made it possible to develop cements for special applications by varying the raw material used in manufacture: By increasing C3S content a high early strength can be obtained. At low heat of hydration cement is made by decreasing both C3S and C3A.

Specific Gravity of Cement - Details & Test Procedure ...

The specific gravity of cement ranging from 3.1 to 3.16 g/cc. By this statement, we can ensure that cement 3.1-3.16 times heavier than water of the same volume. And it sinks in water. Because the specific gravity is greater than 1. Every material consists off so many little pores, which may contain voids in it.

Fineness of Cement - Civil Engineering

Fineness of Cement. The size of the particles of the cement is its fineness. The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process. As hydration rate of cement is directly related to the cement particle size, fineness of cement is very important.

The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength, (Fig. 3). The fineness of grinding has increased over the years.
