Various Cocnrete grades and their mix designs

Question

Accepted Answer

Concrete grades are classified based on their compressive strength. Mix designs vary based on the grade required.

Concrete grades range from M5 to M80, with M representing mix and the number representing compressive strength in MPa.
Mix designs include proportions of cement, aggregates, water, and admixtures to achieve desired strength and workability.
For example, M20 grade concrete typically has a mix design of 1:1.5:3 (cement: sand: aggregates) with water-cement ratio of 0.5.

Accepted Answer

M5 Grade Concrete: 01:05:10 (cement:sand:aggregate) - Lean concrete for basic requirement
M7.5 Grade Concrete: 01:04:08 (cement:sand:aggregate) - Lean concrete for basic requirements
M10 Grade Concrete: 01:03:06 (cement:sand:aggregate) - Balancing strength and practicality
- M15 Grade Concrete: 01:02:04 (cement:sand:aggregate) - Balancing strength and practicality
M20 Grade Concrete: 1:1.5:3 (cement:sand:aggregate) - Robust choices for structural integrity
M25 Grade Concrete: 01:01:02 (cement:sand:aggregate) - Robust choices for structural integrity
M30 Grade Concrete: 1:0.75:1.5 (cement:sand:aggregate) - High strength grade concrete
M35 Grade Concrete: 1:0.5:1 (cement:sand:aggregate) - High strength grade concrete
M40 Grade Concrete: 1:0.25:0.5 (cement:sand:aggregate) - High strength grade concrete
M45 Grade Concrete: 1:2.42:3.19 (cement:sand:aggregate) - High strength grade concrete
M65 to M100 Grade Concrete: Design Mix - Higher strength grade concrete
