What is the load capacity of M30 concrete when mixed in cubes?

Question

Accepted Answer

M30 concrete has a characteristic compressive strength of 30 MPa, suitable for various structural applications.

Compressive Strength: M30 concrete is designed to achieve a compressive strength of 30 MPa (megapascals) when tested in 150mm cubes.
Testing Age: The standard testing for M30 concrete is typically done at 28 days of curing, which is when it reaches its full strength.
Applications: M30 concrete is commonly used in medium-strength structures like residential buildings, pavements, and precast elements.
Mix Design: The mix design for M30 concrete usually involves a ratio of cement, sand, aggregates, and water, optimized for strength and workability.
Durability: M30 concrete offers good durability and resistance to weathering, making it suitable for various environmental conditions.
