For Testing of soundness of cement.
What is soundness of cement?
Soundness of cement is the property of hardened cement paste undergoing large change in volume after setting without delayed destructive expansion. This destructive expansion is caused by excessive amounts of free lime or magnesia. This change in volume may cause crack and disintegration of concrete.Soundness of cement can be checked by using Le-Chatliers apparatus.

What is the difference between concrete mortar and cement paste?
Cement paste is formed when cement is mixed with water. However, cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.

What is the soundness of cement?
soundness is nothing but volumetric change of the cement .Presents of chemicals such as CaO,MgO will react with the water present in the cement paste and it will increase the volume of cement paste while hardening.It may causes cracks in the building to avoid that it is necessary to find the soundness of cement before using that.It may vary to each type of cement even for each batch.Soundness should not exceed 10mm for OPC.

Aim of le chatelier soundness test?
The aim of the Le Chatelier soundness test is to assess the volume stability of hydraulic cement when subjected to expansion or shrinkage after mixing with water. This test helps determine the quality and durability of the cement by measuring its ability to resist volume changes.
What is the importance of standard consistency test?
by standard consistency test we determine standard consistency of cement which is denoted by p. as we know standard consistency value for a cement its value is used for making the paste for determining setting time, soundness, compressive strength of cement
