Design Concrete Mix Proportions

Design Concrete Mix Proportions : -

As per IRC 465 : 2000 According to Mix Proportions They Classify into 4 (Four) Types.

1 . Lean Mix

2 . Ordinary Concrete

3 . Standard Concrete

4 . High Strength Concrete

1 . Lean Mix : -

•  M5 Grade Concrete
• M7.5 Grade Concrete

M5 Mix Proportion Is 

M5 - 1:5:10

This M5 Mix is 1 percent of  Cement and 5 percentage of Fine Aggregate (Sand) and last Coarse Aggregate 10 percent . 

1    -  Cement

5    -  Fine Aggregate

10  -  Coarse Aggregate

It Gives characteristic compressive strength is 5 N/mm2

M7.5 - 1:4:8

1    -  Cement
4    -  Fine Aggregate
8    -  Coarse Aggregate

M7.5 characteristic compressive strength is 7.5 N/mm2


2 . Ordinary Concrete : - 

1 . M10  - 1:3:6
2 . M15  -  1:2:4
3 . M20  -  1 : 1½: 3

3 .  Standard Concrete : - 

1 : M25 - 1:1:2
2 : M30 - Design Mix
3 : M35 - Design Mix
4 : M40 - Design Mix
5 : M45 - Design Mix
6 : M50 - Design Mix
7 : M55 - Design Mix

4 . High Strength Concrete : - 

1 : M60 - Design Mix
2 : M65 - Design Mix
3 : M70 - Design Mix
