CIP 35 Testing Compressive Strength of Concrete

The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and

Compressive Strength of Concrete & Concrete Cubes

Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc’. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

How to Evaluate Compressive Strength of Concrete

What is the best method for the measurement of compressive strength of concrete? Testing cylinders and cubes in compression is the most convenient and well-known method for measuring the strength.

Hardened Concrete Strength

In construction, concrete is used only for compression, since its contribution to tensile resistance is negligible owing to its low tensile strength. The compressive strength is determined by loading moulded concrete specimens (either cubes or cylinders) in uniaxial compression until ultimate failure. While cubes are advantageous because of the fact that loading on the cast side can be avoided

Procedure: Compressive Strength Test of Concrete Cubes For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15cm x 15cm x 15cm are commonly used.

Compressive and Tensile Strength of Concrete: Relation

Tensile strength of concrete is found more sensitive to the inade­quate curing than compressive strength. This may be due to the non -uniform shrinkage of flexural test beams. As flexural test beams are very sensitive to shrinkage cracks and are very serious for the test.
