compressive strength of m concrete crushing load
What is the difference between crushing strength and ...
Compressive strength is the load (measured in pounds/sq. ... If the load gets large enough, the concrete will fracture and be crushed.The crush strength is the load (similarly measured) at which a slab of specified thickness will begin to show breakup and crushing.There is a spread between these measures.
