Details
M25 grade concrete is a special type of concrete, used for residential and commercial buildings and so many other projects. In M25 volumetric mix, one part of cement, one part of sand (fine aggregate) and two part of coarse aggregates i.e. 1:1:2 ratio of ingredients are mixed with appropriate amount of water properly.
Details
The design of M25 grade concrete mix also takes into consideration the water-cement ratio (W/C). The W/C ratio is the weight of water to the weight of cement used in the mix. For the M25 grade concrete, the W/C ratio is usually kept between 0.4 to 0.55. A lower W/C ratio results in stronger and more durable concrete, but it may reduce …

The aggregate size and shape, desired workability, and use of additives are major influencing factors. Table 4 of IS 10262:2019 specifies 186 kg of water for 1 cubic meter of concrete with 20 mm maximum size aggregate. The slump for this value is 50 mm. Estimated water content for 75 mm slump-. = 186 + (3×186)/100 = 191.58 kg.

Modulus of elasticity. M20 concrete ratio has around 22360 MPa and M25 concrete grade has 25000 MPa of modulus elasticity. It indicates that M25 concrete can withstand higher stress but is brittle than M20 concrete. Hence, cracks will appear sooner on M25 than M20 as low elasticity modulus allows it to bend and deform easily.
