Brick chips are also used as a substitute of stone chips in concrete mix where stone is not available or an economic solution is prefared. In all the abovementioned cases compression load governs. Due to this compressive strength of bricks is a very important parameter.

Concrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness. 1011 In a concrete having a watercement ratio lower than 0.42 hydration stops when there is no more water to hydrate the cement particles. Below this critical value of 0.42 very fine cement particles can be fully hydrated but only the surface of the coarsest ones

Compressive strength is the capacity of a material to withstand axially directed pushing forces. When the limit of compressive strength is reached materials are crushed. Concrete can be made to have high compressive strength e.g. many concrete structures have compressive strengths in excess of 50 MPa whereas a material such as soft sandstone may have a compressive strength as low as 5 or 10
