Compressive strength in concrete test - SlideShare

Feb 6, 2017 . TEST PROCEDURE Scope: • The test method covers determination of compressive strength of cubic concrete specimens. • It consists of applying a compressive axial load to molded cubes at a rate which is within a prescribed range until failure occurs. • The compressive strength is calculated by dividing.

How can I interpret compressive strength of concrete at 28 days?

Hence this period was thought to be a reasonable period and accepted by many people and incorporated in the code of practice of countries so that the engineers can take a decision regarding the quality of concrete in the structure. In case the strength of control specimens like cubes fail to give the compressive strength.

Compressive strength - Wikipedia

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists.
