Concrete Compressive Strength

The compressive strength of concrete is an important parameter to determine its performance during service conditions. It is defined as the concrete's resistance to failure under compressive forces. This test method is for the determination of the compressive strength of molded (cast) or drilled (cored) concrete cylinders. The test method consists of applying a compressive axial load at a prescribed rate until failure occurs.  The compressive strength of the concrete is calculated by dividing the maximum load by the cross-sectional area. Please select units before entering the data.

Cylinder Diameter:		Units:  mm cm m in ft
Cylinder Length:
Maximum Load:		Units:  kN N lbf
Strength:		Units:  MPa kPa Pa kg/cm² psi ksi ksf tsf

Concrete Tensile Strength

This test method determines the tensile strength cylindrical concrete specimens obtained from molds or drilled cores. The test method involves applying a diametral compressive force along the length of the cylindrical concrete specimen at a prescribed rate until failure occurs. Tensile strength is obtained by dividing the maximum load by the appropriate geometrical factors. Please select units before entering the data.
