CALCULATION. Compressive Strength of concrete = Maximum compressive load carried by specimen / Cross Sectional Area surface of specimen. Take it as, Cross sectional Area = 150mm X 1500mm = 22500 mm 2 or 225 cm 2. Assume the compression load is 400 KN, Compressive Strength = (400000 /22500) = 17.77 /9.81 = 181.22 kg/cm2. Note – 1 kg is equal to 9.81 N

Get PriceThe strength of concrete is measure in terms of pounds per square inch (or PSI). PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 PSI. Most concrete has a PSI rating of 2500 to 3000. This type of concrete can be used for sidewalks and residential driveways.
