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.
| Mix | Proportion | Uses |
| M5 | 1:5:10 (Cement:Sand:Aggregate) | For floor PCC or RCC Wall |
| M7.5 | 1:4:8 (Cement:Sand:Aggregate) | For Supportive foundation, cover slab of single room for domestic animals. |
| M10 | 1:3:6 (Cement:Sand:Aggregate) | For Supportive foundation, cover slab of single room for domestic animals, used for PCC floor where movement of load mostly occurs. |
| M15 | 1:2:4 (Cement:Sand:Aggregate) | For Slab, Beam, Column, Stair, etc. Also used for a load-bearing structure like water tank stain |
| M20 | 1:1.5:3 (Cement:Sand:Aggregate) | For Column, Beam, and slab for a multistorey building. |
| M25 | 1:1:2 (Cement:Sand:Aggregate) | For Heavy load, Bridge pile, RCC Road, etc. |
| M30 | 1:0.75:1.5 (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.
