Answer Posted / nisikanta
Take all the cubes & submerg it in water.Then when 7,21,28
days will reach then take out the cube 5 minutes before &
let the surface dry.Then place the cube in Compressive
strength test machine in SSD( saturated surface
dry)condition centrally.When the concrete crushed the
machine will automatically stop & take the reading & then
divide the Force(KN)by its surface area.
