Physical properties of cement The cement to be used in construction must have ceratin given qualities in order to play its part effectively in a structure. When these properties lie within a certain range, the engineer is confident hat inmost of the cases the cement performance will be satisfactory.
Properties of cement are two types physical and chemical. The ingredients of concrete can be classified into groups, namely active and inactive. The active group consists of cement and water, whereas the inactive group comprises fine coarse aggregates. Cement is a well-known building material and has occupied an indispensable place in ...
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.

Field Tests Conducted for Cement: Following four field tests may be carried out to ascertain roughly the quality of cement: (1) Colour (2) Physical properties (3) Presence of lumps (4) Strength. (1) Colour: The colour of cement should be uniform. It should be typical cement colour i.e., grey colour with a …
Physical Tests on Cement. (a) Soundness Test: It is conducted by sieve analysis. 100 gms of cement is taken and sieved through IS sieve No. 9 for fifteen minutes. Residue on the sieve is weighed. This should not exceed 10 per cent by weight of sample taken. (b) Setting Time: Initial setting time and final setting time are the two important physical ...
