What Is Grades of Concrete Mixed
GRADES OF CONCRETE
The Grade of Concrete can be found by
calculating the compressive strength of
concrete in Mpa, where M stands for mix and the pa denotes the overall strength.
If we
mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days.
