Use of M5, M10,M15,M20 and M25 in Residential building

Hello, friends in this article I am going to tell you about how to use mix of concrete-like M5, M10, M15, M20, or M25 in residential buildings.

Friends first of all I would like to tell you what is M5, M10, M15, M20…..etc. Here M is grade of mix ratio and numerical values 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.

MixProportionUses
M51:5:10 (Cement:Sand:Aggregate)For floor PCC or RCC Wall
M7.51:4:8 (Cement:Sand:Aggregate)For Supportive foundation, cover slab of single room for domestic animals.
M101:3:6 (Cement:Sand:Aggregate)For Supportive foundation, cover slab of single room for domestic animals, used for PCC floor where movement of load mostly occurs.
M151:2:4 (Cement:Sand:Aggregate)For Slab, Beam, Column, Stair, etc. Also used for a load-bearing structure like water tank stain
M201:1.5:3 (Cement:Sand:Aggregate)For Column, Beam, and slab for a multistorey building.
M251:1:2 (Cement:Sand:Aggregate)For Heavy load, Bridge pile, RCC Road, etc.
M301:0.75:1.5 (Cement:Sand:Aggregate)For Heavy load, Bridge pile, RCC Road, etc.

Now let us move toward where we can generally used the different types of mix ratio of concrete in residential building.

Here I will discuss from M5 grade of concrete to M25 grade of concrete. There are also other higher strength of concrete but here I will discuss this much only.

So let’s start, Use of M5, M10,M15,M20 and M25 in Residential building

1) Mix – M5

Proportion :- 1:5:10 (Cement:Sand:Aggregate)

Uses :-
This types of mix are used for floor PCC or RCC Wall.

2) Mix – M7.5 & M10

Proportion for M7.5 :- 1:4:8 (Cement:Sand:Aggregate)

Proportion for M10 :- 1:3:6 (Cement:Sand:Aggregate)

Uses :-
This types of mix are used for Supportive foundation, cover slab of single room for domestic animals, used for PCC floor where movement of load are mostly occurs.

3) Mix – M15

Proportion :- 1:2:4 (Cement:Sand:Aggregate)

Uses :-
This types of mix are used for Slab, Beam, Column, Stair etc. Also used for load bearing structure like water tank stain.

4) Mix – M20

Proportion :- 1:1.5:3 (Cement:Sand:Aggregate)

Uses :-
This types of mix are used for Column, Beam and slab for multistorey building.

5) Mix – M25 and M30

Proportion :-

M25-1:1:2 (Cement:Sand:Aggregate)

M30 -1:0.75:1.5 (Cement:Sand:Aggregate)

Uses :-
This types of mix are used for Heavy load, Bridge pile, RCC Road etc.

So, friends, I hope the article about “Use of different grade of concrete in Residential building” remains helpful for you.
