Compressive strength of cement -(Procedure and formula

Strength is the most important property of cement. The compressive strength test of cement is done because, with an increase in compressive strength of cement strengths such as flexural strength, resistance to abrasion, and so on also increases.With one test we can determine various aspects of cement and can decide the suitable types of cement for the construction site.
