Are you asking for The rate of Concrete block or The rate of different items like cement, sand, aggregate?
Rate analysis of concrete block:
Important points :
Tools for cement mortar and Labour estimation :
Important note :
Very high charges for the mechanical mixer is to be taken in in a lump sum for mixing 1-metre cube of mortar.
Rate analysis will simply the quantity of cement and sand required for the 1-meter cube of cement sand mortar.
Similarly, we can do rate analysis for concrete as well for different proportions.
Here I am discussing point example of the material required for the 1-meter cube of cement concrete of density 2.3 ton per metre cube and cement sand aggregate ratio is 1:3: 6
Mix proportion ratio is 1:3:6 (here, maximum 20 nominal sizes of aggregates are used.)
The total sum is 1+ 3 + 6=10 Dry volume of 1-metre cube concrete is a 1.54-metre cube.
Hence cement required is a one-tenth part of the 1.54-meter cube which is 0.15-metre cube means to 16 kg means 4.3 bags of 50 kg each.
If you want to find out the sand quantity then it’s 0.46-meter cube means 1.2-ton Aggregate quantity 0.92-metre cube means 1.56 ton of maximum normal size of 20 mm aggregate
I hope so your doubt is clear, thank you.
