Different mix proportions of the materials used to make concrete namely. Cement; Coarse aggregate; Fine aggregate; Water

MoreThe flexural strength of concrete was found to be 8 to 11% of the compressive strength of concrete of higher strength concrete of the order of 25 MPa (250 kg/cm 2) and 9 to 12.8% for concrete of strength less than 25 MPa (250 kg/cm 2) see Table 13.1: . The ratio of flexural strength to compressive strength was found higher for 40 mm maximum size aggregate

MoreTable: Compressive Strength of Different Concrete Mixes. The compressive strength of concrete can be calculated by the failure load divided with the cross sectional area resisting the load and reported in pounds per square inch in US customary units and mega pascals (MPa) in SI units. Concrete's compressive strength requirements can vary from

MoreDec 08, 2017· And the number following “M” represents compressive strength of that concrete mix in N/mm 2 after 28 days. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm 2. You can also watch our video here: Video on concrete mix ratio of various grades of concrete. Concrete mix ratio table

MoreWhere M stands for Mix ration & 5 stands for compressive strength of a 150mm cube after 28 days of curing, expressed in N/mm2 The mix ratio is 1:5:10 (1 Cement, 5 Sand and 10 Aggregate) Application/use: To provide the uniform surface of the foundation concrete and to prevent the direct contact of foundation concrete from the soil.

MoreTensile strength of concrete is 1/10th of compressive strength of concrete. If we are using M20 then it's compressive strength is 20 N/mm2 and it's tensile strength is 2 N/mm2.
