The mixes of grades M25 correspond approximately to the mix proportions (1:1:2) respectively. What Is M30 Grade? M30 represents the concrete mixture that, after 28 days of curing, will give a resistance of 30 N / mm 2. At my site, for building construction, the M30 is being used. The proportion of ingredients is as follows for the concrete mix M30 (In liters): – CEMENT – 35 It. Fine ...

Grade of Concrete Nominal Mix proportions (Cement: FA : CA) M 5 1:5:10 1:4:8 M10 1:3:6 M15 1:2:4 M20 1::3 . DESIGNED MIXES In these mixes the performance of the concrete is specified by the designer but the mix proportions are determined by the producer of concrete, except that the minimum cement content can be laid down. This is most rational approach to the selection of mix ...

So, if we have M20 grade concrete then we can say that its grade is 20KN/mm². And mix proportion is 1::3 which indies 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. Use of M5, M10,M15,M20 and M25 in Residential building. Now let us move toward where we can generally used the different types of mix ratio of ...

· Type M mortar mix has the highest amount of Portland cement and is recommended for heavy loads and belowgrade appliions, including foundations, retaining walls, and driveways. While type M mortar provides at least 2,500 psi of compressive strength, it offers relatively poor adhesion and sealing properties, making it unsuitable for many exposed appliions. Type M is preferred for use .
