Compression Testing. In the United States, the

**compressive strength**of concrete

is established from compression tests on cylindrical specimens of 6-in. diameter

and 12-in. height (ASTM C39, "

**Compression Strength**of Cylindrical Concrete ...

For normal-weight concrete, it can be computed (in psi) as: /, = 6.7X(/;f (with

**compressive strength**in psi units). As can be confirmed from the equation, the

tensile strength of concrete increases with its capacity in compression. As a

general rule ...

The capacity to bond individual units is measured by the tensile bond strength of

mortar, which is related to the force required to ... Increase in

**compressive**

**strength**, which is the most important property of concrete, is not accompanied by

a ...
