Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
With constant research and development in the field of cement technology and its manufacturing process,a M20 mix of "1:1.5:3″(by volume) would be too rich,over engineered and uneconomical (~7.5 bags of cement per cum) and will ultimately result into a M30 concrete and above, the reason being latest generation of 53 grade OPC cement is ...

Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. 1.Cement = 6 bags ...
The design of reinforced concrete water tank is based on IS 3370: 2009 (Parts I – IV). The design depends on the location of tanks, i.e. overhead, on ground or underground water tanks. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of reinforced concrete or even of steel.
The quantity of water required for this proportion per bag of cement (50 kg) is about 30 liters. However, for RCC work in beams, pillars, walls and others, a proportion of 1:1.5:3 is used which requires about 25 liters of water per bag of cement. Quality of concrete.
Strength of RCC 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 Cubed) compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8.
Jul 26, 2020· High strength concrete grade are M50,M55,M60,M65, & M70 are made according to design mix have higher compressive strength than normal and standard grade of concrete..
