Calculator for Nominal Design of Concrete Mix for different proportions of cement and aggregates.(SI units)

Concrete Mix Design
Reinforced concrete slab

This calculator is useful for nominal design of concrete mix of different proportions M25 (1:1:2), M20 (1:1.5:3), M15 (1:2:4), M10 (1:3:6), M7.5 (1:4:8). You can get the dry amount of ingredients (cement, fine aggregate and coarse aggregate) of concrete as well as the amount of water needed to produce concrete of desired workability. For example M15 corresponds to a Mix for Concrete with characteristic compressive strength of 15 MPa (15 N/mm2) and the mix proportion 1:2:4 concrete means 1 part of cement mixed with 2 parts of fine aggregate (sand) and 4 parts of coarse aggregat (stone pieces). Water is essential for producing concrete. The water to cement ratio is generally selected in the range of 0.4 to 0.6 depending on required workability. Desnsity of cement is taken as 1440 kg/m3. It is assumed that dry volume of concrete = 1.54 times the wet volume of concrete. This calculator gives the dry volume of agggregates. If you want to determine the weight of aggregates just multiply the dry volume by the bulk density of aggregate. This calculator is based on the guidelines of IS codes.

Please enter the volume of wet concrete to be produced and select the desired concrete grade with appropriate water to cement ratio in the form given below and start calculations.
