01/01/2021· After 7, 14 and 28 days compressive strength results of M30 mix yielded a value of 25 MPa, 37 MPa and 41 MPa respectively. The optimum percentage of rice husk ash has been found as 15% and the 28th day compressive strength yielded a value of 47 MPa.Very fine particle size of rice husk ash contributed for packing effect of the pores in the concrete thereby increasing the compressive strength.

Using whatever cement or admixtures; if your concrete is M30 then at seven day your strength should be 65 % of 30. 0.65 X 30= 19.5 N/ mm2 or MPA .

Concrete mixtures are defined in ascending numbers of 5, starting at 10, and show the compressive strength of concrete after 28 days. For example, C10 has a force of 10 newtons, C15 has a force of 15 newtons, C20 has a force of 20 newtons, and so on. Different mixtures (M) occur in various mixing ratios of the various cement, sand, and coarse aggregate ingredients. For example, M20 comes in,

No strength test falls below the specified compressive strength by more than 500 psi (3.5 MPa) if the specified compressive strength is 5000 psi (35 MPa) or less; or by more than 10 percent of the specified compressive strength if the specified compressive strength exceeds 5000 psi (35 MPa).
