• Compressive and Tensile Strength of Concrete: Relation ...

    The 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 % for concrete of strength less than 25 MPa (250 kg/cm 2) see Table : . The ratio of flexural strength to compressive strength was found higher for 40 mm maximum size aggregate than that of 20 mm max sized aggregate.

    01/01/2018· It was found that the compressive strength of the carbonated concrete blocks reached the highest level when the RH was at %. When the RH was at %, it decreased the compressive strength significantly. This is because the chemical reactions between CO 2 and the cement components are initiated with the dissolution of CO 2 in water.
