DRYING SHRINKAGE OF CEMENT IS 4031 part 10

drying shrinkage

DETERMINATION OF DRYING SHRINKAGE OF HYDRUALIC CEMENT Drying shrinkage is defined as the contracting of a hardened concrete due to the loss of capillary water. Drying shrinkage occurs when water starts evaporating from the exposed surface . Due to this drying shrinkage, cracks are noticed on the surface of cement concrete. TEST STANDARD: IS 4031-Part …

STANDARD CONSISTENCY OF CEMENT | TEST METHOD

Consistancy test of cement by vicat apparatus

What is Consistency of Cement? The standard consistency of cement paste is the percentage of water required, where the plunger penetrates into the cement paste of about 5mm to 7mm from the bottom of the mould and in the other word consistency of cement is the minimum amount of water required to initiate a chemical …
