1. objective. The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (f ck)- as per Indian Standards (ACI standards use cylinder of diameter 150 mm and height 300 mm).The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
What is concrete compressive strength test? Compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing. The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.
