04-11-2020· Answer by Mihir Salanke: Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates). So if you need 4cu.m of M25 concrete, we need to have 1cu.m of cement. So, theoretically, for 1cu.m of M25 concrete, we need to have 0.25cu.m of cement. But in practice, whenever we estimate quantity of cement for concrete…
Here M is grade of mix ratio and numerical value 5, 10, 15, 20…etc are strength of concrete in KN/mm². So, if we have M20 grade concrete then we can say that its grade is 20KN/mm². And mix proportion is 1:1.5:3 which indicates that in this types of mix ratios 1 part is cement, 1:5 part is sand and 3 part is aggregate has been used to make this concrete.
Mix proportioning for a concrete of M25 grade is given in A·I to A-ll. A·I STIPULATIONS FOR PROPORTIONING. a) Grade designation : M25 b) Type of cement : OPC 53 Grade conforming IS 12269 c) Maximum nominal size of aggregate : 20mm d) Minimum cement content : 300 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.50 (Table 5 of IS 456:2000)
In this article we are discussing about concrete mix ratio and ideal mix concrete. Making concrete, it is important to use the correct concrete mixing ratios to produce a tough, long life, durable concrete mix. To make concrete, four basic materials you need: Cement, sand, aggregate, water, and add-mixture.
If you mean nominal mix proportion, it's as said in other answers, it's 1:1.5:3 and 1:1:3, for M20 and M25, respectively, FOR 33 GRADE Cement. For higher grades of cements, multiply the sand and metal ratios by the grade of cement and divide by 33...
05-03-2021· We can also prepare this grade on-site with our normal concrete mixture, but for mixing this manually we need to know about the rate analysis of M25 grade concrete. this analysis is generally based on Mix design which is prepared by the Laboratory where we can know about the Specific gravity of the material which is very useful to prepare rate analysis of M25 grade concrete.

The Mix Design process is normally implemented for the structure that needs higher grades of concrete like M25, M30, etc, and where consumption of Concrete is high. Concrete Mix Design for M20, M25, M30, and higher grades of concrete can be calculated from the example given below.
So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates. The concrete mix design involves various steps, calculations and laboratory testing to find right mix proportions. This process is usually adopted for structures which requires higher grades of concrete such as M25 and above and large construction projects where quantity of concrete consumption is huge..
