Types Of Concrete Mix Ratio Design And Their Strengths

Types Of Concrete Mix Ratio Design And Their Strengths

Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures Compressive strength of concrete depends on many factors such as water cement ratio cement strength quality of concrete material quality control during the production of concrete etc Test for compressive strength is carried out either on a cube.From Table 1 for all the concrete grades strength classes the cylinder strengths are higher than the cube strengths For example the concrete grade strength class C20 25 concrete is expected to have a minimum cylinder crushing strength of 20MPa and the same C20 25 concrete is expected to have a minimum cube crushing strength of 25MPa Concrete.
