MANUAL on CONCRETE LABORATORY - VSSUT

2018-6-25 · : Cement is obtained by grinding various raw materials after . The degree calcination to which cement is ground to smaller and smaller particles is called fineness of cement. The fineness of cement has an important on the rate of hydration and hence on the rate of role gain of strength and also on the rate of evolution of heat.

Compressive Strength Test Of Concrete Cubes -

Compressive strength as a concrete property depends on several factors related to the quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common]

1 Lab Manual of Concrete Technology

2015-1-13 · 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.
