How To Do Cement Tests Structural Guide

FINENESS TEST ON CEMENT. Piratical size of the cement is directly affecting the strength of the concrete. Finer partials react very quickly than the comparatively large particles. Further, fine cement has a greater surface area and hence faster the development of strength. There are two methods of testing of fineness of cement. By sieving

Testing Of Cement: Physical Tests (IS: 4031)

Testing Of Cement: Physical Tests (IS: 4031) Fineness Test . The degree of fineness of cement is the measure of the mean size of the grains in it. There are three methods for testing fineness: the sieve method-using 90 micron (9 No.) sieve, the air permeability method-Nurse and Blains method and the sedimentation method-Wagner turbidimeter method.

Sieve analysis Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
