The Civil Engineering Data Standards manual states the density of many grades of concrete. Standard density for fresh M-25 concrete is: 2414 Kg/ M3.
The density of reinforced concrete is 2500 kg/cum or 25 kn/cum
The Civil Engineering Data Standards manual states the density of many grades of concrete. Standard density for fresh M-25 concrete is: 2414 Kg/ M3.
Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m

In grade 25 concrete, which typically has a mix ratio of 1:1:2 (cement:sand:aggregate), approximately 0.5 cubic metres of sand is required per cubic metre of concrete. Since the density of sand is about 1,600 kg per cubic metre, this translates to around 800 kg of sand needed for one cubic metre of grade 25 concrete. This amount can vary slightly based on the specific mix design and moisture content of the sand.
1:1:2
M 25
1:1:2
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.
cement consumption in M-25
in a simple way it is the strength of concrete, which it can bear the loads of its specified grade ex C 25 grade can resist the weight of 25kn/m2 after 28days of 60% after 7 days.
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
