Because of the time delay in obtaining the test results for concrete crushing strength,
Get MoreBricks are mainly used in construction of wall, floor, cornices and arches. 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 above-mentioned cases, compression load governs. Due to this, compressive strength of bricks is a very important parameter.
Get MoreThe characteristic compressive strength f ck is the first value in the concrete class designation, e.g. 30 MPa for C30/37 concrete. The value corresponds to the characteristic (5% fractile) cylinder strength according to EN 1. The strength classes of EN 1 are based on the characteristic strength classes determined at 28 days.
