Chat OnlineCompressive strength of cement -(Procedure
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.

Compressive strength as mentioned is obtained by conducting compression test on a concrete sample (Cylinder or cube) of a given mix design. The failure load of the given sample divided by the area of cross-section of the sample gives the compressive strength of the specimen. In takes the value in Mega Pascals (MPa) or in Pound-force per square inch (psi).

After 7 or 28 days the cube is dried,then it is kept in a UTM (universal testing machine) or a compressive testing machine and load is applied till failure (cracks). This load is divided with the face area to arrive at the compressive strength, appropriate units can be used (usually N/mm^2 or Mpa). This methodology is done for a single cube.
