How to calculate compressive strength of concrete?
Answer Posted / bhausaheb mane
Cast the cube moulds of size of (150mmx150mmx150mm)
after curing period of 3,7,28 days test under compressive
testing machine.then caclculate result by using formula
Compressive strength =load in newton/Area of cube in mm2
(150x150)
generally compressive testing machine shows load in
Kilonewton so we required Kilonewton convert in to the
Newton.by multiplying kN X 1000 (1N = 1000 kN)
e.g.
load by machine 300 kN/Area of cube 22500mm2
Load in newton 300x1000/22500mm2=13.33 N/mm2
