What is unsoundness of cement?
when we test the cement with the help of Le-Chatlier apparatus and then we found if the expansion is more than 10 mm then the cement is said to be unsoundness
What ways by which unsoundness of cement may be reduced?
Unsoundness in pozzolanic materials may be reduced by adding minor components such as alkalis or carbon which is also responsible for the color
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 meant by binder material in concrete?
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
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.
Is limestone good for building?
It is an important cement ingredient and its proportion must be carefully maintained. It occupies the percentage of 60-67%. The lime in excess makes the cement unsound and causes the cement to expand and disintegrate.
