Soundness of Cement
The clear indicator leg length of Le Chatelier's apparatus is____.
What is the height of the mould used in the experiment?
)The split cylindrical mould of Le- Chatelier's apparatus is made up of?
The average expansion of OPC, PPC and Rapid hardening cement should not exceed _____?
Super Sulphated cement should not expand more than ____?
The cement sample is immersed in boiling water for a fixed period of time.
How do we determine the soundness of cement, if L1 is measured at a temperature of 27 ± 2° C after 24 hours and, L2 is measured after submerging and boiling the mould for 3 hours?
In the Le- Chatelier's method, pressure is also applied to the cement sample.
What is the standard time interval for measuring the initial length (L1) of the Le Chatelier's mould after preparing the cement sample?
The difference between the distance of the indicator legs before and after boiling gives the _____ of the cement sample.
