Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubic') compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally …

Well, 1 Cubic meter of M20 grade grade of nominal mix having proportion 1:1.5:3 reuires 397 kg of Cement. Well that may get change depending upon the design grade. But 1m3 M20 grade concrete reuires:-397 Kg Cement 041 M3 Sand 0.82 M3 aggregate.

Concrete cost per cubic metre sits at average $250 to $300/m3 for the material only whereas it can start at low $160/m3 and reach even $550/m3 plus GST. You also need to count in $60 to $80 per hour for concreters' labour rates when calculating concreting costs on a per-cubic-metre basis. Get Price. Learn More.

Concrete Mix design of M20, M25, M30 and higher grade of concrete can be calculated from example below. Contents: Concrete Mix Design. ... In the present example against mild exposure and for the case of reinforced concrete the minimum cement content is 300 kg/m 3 which is less than 383.2 kg/m 3. Hence cement content adopted = 383.2 kg/m 3.

Calculate the concrete quantity required in cubic meter and then multiply the quantity with the cement sand and aggregate for 1 cubic meter of concrete. In your case Volume of concrete 1.7 x 1.7 x 0.5 1.4 cu.m It looks like you are using m20 grade mix with extra sand. If you follow that mix proportion then to calculate use this following method.
