The consistency of cement mortar is its ability to flow. The consistency test on cement is performed to determine the water necessary for attaining standard consistency or normal consistency.

The heat of hydration is the heat liberated from the reaction between cement and water. Cement is a binding material. It consists of ingredients such as lime, Silica, Alumina etc. Water is added to cement to make it adhesive so that we can use it in construction. This article is about the heat of hydration of cement.

Soundness test determines the disintegration of aggregates due to weathering. This includes freezing, thawing, marine condition etc. However, the weak and porous aggregate shows a change in weight during this soundness test.

The soundness of the cement is the ability to resist volume changes after hardening. The soundness test on cement is significant because,using unsound cement leads to cracks and hamper the structural quality. A sound cement is one of the key materials used in construction. Therefore it is essential to determine its quality before using it in construction.
