M20-grade concrete rate analysis.

What is M20-grade concrete? The term M in M20 refers to "mix," whereas 20 is its compressive strength after 28 days of curing, i.e., 20 MPa or 20 N/mm2. In the present scenario in Nepal, M20-grade concrete is generally used for column and slab casting in RCC structures. In order to calculate the unit rate of M20 in Nepal, you need to consider two basic codes or norms...
