consistency test of cement - test procedure importance

Procedure for Standard Consistency of Cement Keep the vicat apparatus on a level base (when using vicat apparatus with dashpot keep the bearing movable rod to its highest position and pin it ) Unscrew the top of the dashpot Half fill the dashpot with any suitable A field test of cement gives the idea about its basic quality based on its colour smoothness touch and feel at first look without any big apparatus They are the very common and easiest way to check the quality of cement They are very helpful when the cement is

Initial Setting Time

Importance: Test for Setting Time: This test is carried out to find whether a cement sets at a rate suitable for a particular work There is no necessary relationship between the time of setting and that of hardening or attaining the maximum strength A slow setting

Therefore cement is always tested for strength before important works Strength tests are not conducted on neat cement as it causes shrinkage and cracking Thus the cement mortar is used in this test Type and nature of the cement also plays a vital role in

What is Consistency of Cement? A Minimum quantity of water required to initiate the chemical reaction between water and cement to form a paste is known as consistency of cement Standard Consistency – It is that cement consistency which will allow the Vicat plunger to penetrate to 5-7 mm point from the bottom of Vicat mould is known as standard consistency
