Compressive Strength of Concrete using Cylindrical

Aug 24, 2020 Calculation of Compressive Strength of Concrete. Compressive strength of cylinders is calculated by dividing the maximum load at failure by average cross sectional area and express the results to nearest 0.1 MPa [10 Psi]. Cross sectional area of cylinder can be calculated by measuring the diameter of cylinder on both sides.

Compressive Strength of Concrete Cube Test, Procedure

Mar 22, 2020 Compressive strength of Concrete Formula: The Compressive strength of specimen can be calculated by dividing maximum load carried by the specimen by cross-sectional area of the specimen cubes. The surface area of specimen: = 150 x 150 = 22500mm² = 225cm². Assume, The Max compression load is 450KN. 1KN = 1000N ; 450Kn = 450×100 = 450000N

Rebound Hammer Test & Concrete Strength Calculation

Rebound Hammer Test on concrete is a Non-destructive testing method of concrete that provides a convenient, fair, and rapid indication of the compressive strength of the concrete. The concrete Rebound Hammer Test is also known as the Schmidt hammer test that consists of a spring-controlled mass that slides on a plunger within a tubular housing.

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 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 than that of 20 mm max sized aggregate.
