Strength of Hardened Concrete Building Materials ...

The compressive strength of hardened concrete is one of the most important and useful properties of concrete. In most of the structural uses, the concrete is used mainly to resist the compressive stresses. In situations where the shear or tension strength is of importance, the compressive strength is usually used as a measure of these properties.

Hardened Concrete: Properties of Hardened Concrete

Properties of hardened concrete: 1. Strength: The strength of concrete is defined as the maximum stress it can withstand or the maximum it can yield. Cubes, cylinders and prisms are 3 types of compression test specimens. Flexible tensile tests are used to estimate the load at which concrete members can crack, while compressive strength is taken ...

Compression Tests on Hardened Concrete Protocol

For the compression test, the load capacity has to be very high (300,000 lbs or 300 kips or more) in order to test high strength concretes, as the 12 in. cylinders have an area of 28.2 in. 2, and concrete strengths can range up to 20 ksi in practical applications. This type of concrete will require a machine with a capacity of at least 600 kips.

Core diameters should be a minimum of two times the maximum aggregate size. The preferred core diameter for a compressive strength specimen is three times the maximum aggregate size of the concrete (see section 7 of ASTM C 42). Length-to-diameter ratios are ideally 2:1, but this test method provides correction factors for ratios as low as 1:1.
