M25 concrete mix ratio. Its compressive strength is 20 mpa. A volume of concrete 1 m 3 b volume of cement mass of cement specific gravity of cement x 1000 336 3 15 x 1000. If we mention m10 concrete it means that the concrete has 10 n mm2 characteristic compressive strength at 28 days. The mix calculations per unit volume of concrete shall be as follows.

The m refers mix and number after m m10 m20 indicates the compressive strength of concrete after 28 days of curing and testing. Procedure for concrete mix design of m25 concrete step 1 determination of target strength. M 25 concrete mix design. Answer brajesh kaurav.

Minimum cement content mort h 1700 3 a 310 kg m 3. Maximum water cement ratio mort h 1700 3 a 0 45. Used for construction of slabs beams columns etc. Aggregate 1 2 4 or cement.

Here is the comprehensive table for concrete mix ratio of various grades of concrete m7 5 m10 m15 m20 m25 m30 m35 m40 with water content ratio. F target f ck 1 65 x s 25 1 65 x 4 0 31 6 n mm 2. Maximum nominal aggregate size. Ratio of m10 1 3 6 m15 1 2 4 m20 1 1 5 3 that rattio is nominal mix basis above m20 than mix design is preford basically m25 consider is 1 1 2.

The dry volume of concrete mixture is always greater than the wet volume. Opc 53 grade confirming to is 12269 1987. The ratio of dry volume to the wet volume of concrete is 1 54. In this case standard deviation is taken from is 456 against m 20 is 4 0.

M25 grade mixing ratio is 1 1 2 1cement part. 1 sand part 2aggregate part. As per is 10262 2009 mort h. M indicates the proportion of materials like cement.

Used as reinforced cement concrete rcc. What is m25 grade concrete ratio in concrete mix design in m 25 grade concrete m is stand for mix and numerical figure 25 is stand for characteristics of compressive strength of concrete 25 n mm2 gain after curing period of 28 days from initial construction of structure. Mixing ratio is 1 1 5 3 1cement part. So 1 54 cum of dry materials cement sand and aggregate is required to produce 1 cum of concrete volume of cement required 1 1 2 4 x 1 54 1 7 x 1 54 0 22 cum.
