The equivalent concrete for M-30 cylinder strength is M-40 cube strength
M30 concrete is commonly used in foundations due to its high compressive strength of 30 MPa, which provides adequate support for various structures. Its balanced mix of cement, aggregates, and water ensures durability and resistance to environmental factors. Additionally, M30 concrete offers good workability, making it easier to place and finish in foundation applications. This strength and reliability make it suitable for both residential and commercial construction projects.
around 22.. the basic rule is around 70% of target mean strength..
we use M30 grade concrete commercial slabs like shopping malls . college buildings
The weight of concrete can vary slightly depending on its composition, but generally, M30 grade concrete has a density of about 2,400 kg per cubic meter. Therefore, 1 cubic meter of M30 concrete weighs approximately 2.4 tons.
Seven days strength of any concrete usually comes 67% of 28 day strength. So 7 day strength of M30 may be .67*30=20.10 MPa
