What is mixing ratio for concrete grade 30
It is the amount of cement, and sand to be used. It is a different proportion used for each specific type of construction depending on the structure needs.
1:0.75:1.5
Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m

M20 refers to the grade of the concrete generally used in construction purpose. Here, M refers to mix & number 20 refers to the characteristic strength of concrete. the proportions of this grade is (1:1 1/2: 3). Along with this there are some more grades used in constructions i.e., M5, M7.5, M10, M15, M25, M30................. M80
M 15 grade - 1:2:4Cement bags required - 6.5 bagsCement required - 325 kgs
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
1:1:2
Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m

The equivalent concrete for M-30 cylinder strength is M-40 cube strength
M 25

Concretes from grade M-60 to M-80 are called as high strength concretes as per IS 456-2000
cement consumption in M-25
260 kg/cu m
The ratio of cement, sand and crushed stone in M 25 grade concrete is 1:1:2.In this grade of concrete a compressive strength not less than 25 N/mm2 is achieved in 28 days.
