Compressive Strength of Concrete Cubes - Lab Test & Procedure a environmental friendly solution is prefered i.e. 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. The compression strength of concrete is a measure of the concrete's ability to resist loads which tend to compress it. 2. 1 Nano Cement Particles Compressive strength of the concrete increased with increasing specific surface area of nano fume (20 m2/g to 130 m2/g).
