Rapid hardening cement is more finer cement than other cement. Due to fitness it produce a lot of heat. And it is more chances to crack occur in structure. We do not use rapid hardening cement without ...
Cement Consistency Test Standard Consistency Of Cement
The fineness of cement. We have discussed this in specific gravity of cement Manufacturing Defects By Standardising the consistency of cement, we know that how much of water is required to produce an effective cement which will eventually produce good quality of concrete.

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.
What Is The Significance Of Fineness Of Cement
Jul 29, 2020 The fineness of cement is property of cement which indicate the particle size of cement and specific surface area and thus indirectly effect heat of hydration. Importanceeffect of fineness of cement 1. Fineness of cement affects hydration rate hence the rate of strength gain. 2. Bleeding can be reduced by increasing fineness.
How To Do Cement Tests Structural Guide
In addition, water-cement ratio, fineness of cement and curing, placing temperature, etc. also affected to the heat of hydration of the cement. Testing of the heat of hydration can be done as per the BS EN 196-8 2010 by solution method or BS EN 196-92010 by semi-adiabatic method.
