Compressive strength of concrete cube ... for Testing Materials ASTM C39/C39M provides Standard Test Method for Compressive Strength of Cylindrical Concrete ...
The rationale for the suspension was the absence of an ASTM test method for testing the compressive strength of fieldcured mortar. Conversely, there is an ASTM standard test method for testing the compressive strength of the .
Compressive strength of concrete is one of the most important and useful properties. As a construction material, concrete is employed to resist compressive stresses. While, at loions where tensile strength or shear strength is of primary importance, the compressive strength is used to estimate the required property.
How can I interpret compressive strength of concrete at 28 days? It is known that; many of specifiion stipulates that samples compressive strength of concrete must be at least "fck+delta (MPa)" at 28 days.
Effect of curing duration on compressive strength development is presented in Figure 1. Figure 1. Moist Curing Time and Compressive Strength Gain. Higher curing temperatures promote an early strength gain in concrete but may decrease its 28day strength. Effect of curing temperature on compressive strength development is presented in Figure 2. .

ASTM's "Manual of Aggregate and Concrete Testing," included in Vol. of Annual Book of ASTM Standards, states that the conical fracture is typical. In cases where the compressive strength is lower than anticipated, the manual suggests that fracture type may help in determining the cause.
Cylinders made in accordance with ASTM C31 can be tested to failure in the vertical position for compressive strength (ASTM C39) or instrumented and tested for Modulus of Elasticity and Poisson's Ratio (ASTM C469). Cylinders can be placed horizontally and tested for splitting tensile strength (ASTM C496).
ASTM C109 describes the methodology for testing the compression strength of mortars using cubes of material that are 2 inches on a side.
