What Is Fineness of Cement. The fineness of cement is a measure of cement particle size and is denoted as terms of the specific surface area of Fineness Test of Cement is done by sieving cement sample through standard IS sieve. The weight cement particle whose size greater than 90 microns is determined and the percentage of retained cement particle are .

The purpose of this test is to determine the percentage of water required for preparing cement pastes for other tests. Take 300 gm of cement and add 30 per cent by weight or 90 gm of water to it. Mix water and cement thoroughly. Fill the mould of the Vi apparatus and the gauging time should be to minutes.

Strength is the most important property of cement. The compressive strength test of cement is done because, with an increase in compressive strength of cement strengths such as flexural strength, resistance to abrasion, and so on also one test we can determine various aspects of cement and can decide the suitable types of cement for the construction site.
