how much tensile strength of M20 grade concrete at 28 Days
M20
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.
what is the slump value for M20 concrete
1:2:4
M20 - 6.20bags
it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....
260 kg/cu m
The mean grade of M20 concrete is defined by its compressive strength of 20 MPa (megapascals) at 28 days. This grade typically consists of a mix ratio of 1 part cement, 1.5 parts sand, and 3 parts coarse aggregate by volume. M20 concrete is commonly used for structural applications where moderate strength is required, such as in beams, slabs, and columns.
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
In M20 grade concrete, the mix ratio is typically 1:1.5:3 (cement: sand: aggregates). For one cubic meter of concrete, you generally need about 7 to 8 bags of cement, as one bag of cement is approximately 50 kg. This equates to roughly 350 kg of cement per cubic meter, which aligns with the M20 mix design requirements.
