Concrete Material Calculation / Concrete Quantity
- Civil material calculation involves determining the required quantities for various tasks such as concrete, bar bending, plumbing, flooring, and electrical.
- Concrete is composed of cement, sand, aggregate, water, and admixtures in specific proportions to create different grades.
- The first step in concrete quantity calculation is to determine the proportions of material like M 15 ratio is 1:2:4 and M20 is 1:1.5:3.
- The volume of fully compacted concrete is equal to the absolute volume of all the materials of concrete.
- The volume of a rectangular cross-sectional member may be calculated as Length x Width x Height/Depth/Thickness.
- The formula for concrete material calculation is Vc = Vce + Vf + Vca + Vw.
- As an example, for M15 grade concrete (1:2:4 proportions), Vce in bag = 5.58 bag, Vf = 658.75 kg (Fine Aggregate in kg), Vca = 959.06 kg. (Coarse Aggregate in kg), and Vw = 87.22 liters (Water in Liter).
- The specific gravity of materials is important because it helps convert volume measurements to weight measurements.
- To convert the volume of cement from cubic meters to bags, you can use the conversion factor of approximately 0.034722.
- The water-cement ratio (w/c) is determined based on design codes and standards, such as IS Code 456.
