MoreWhat Is M25 Grade? It is a grade of concrete that would achieve a compressive strength of 25 N / mm 2 after 28 days of curing. It is made by mixing cement, fine aggregates and coarse aggregates in a 1: 1: 2 ratio, keeping the water-cement ratio between 0.4 and 0.6. What Is M30 Grade?

MoreTo find the design mix ratio, divide the calculated value of all materials by the weight of cement. Therefore Mix Design Ratio of M25 Grade concrete by weight is Cement: F.A: C.A: Water = 1: 1.9 :3.1 : 0.50. Note: This is a Design mix ratio by weight which is

MoreMany entry-level civil engineers and students believe that Mix ratio of M25 grade concrete is 1:1:2. This is a very common misconception. There are two reasons why the M25 concrete Mix ratio is not 1:1:2 and they are explained in this article.

MoreM25 grade concrete is made by mixing cement, sand and coarse aggregates in a 1: 1: 2 ratio ( 1 part is cement,1 part is sand and 2 part is cement) in which keeping the water-cement ratio between 0.4 and 0.6. M25 grade concrete ratio is 1:1:2 ( mixture of cement, fine aggregates and course aggregate) is used for cement bags required for m25
