What is Cube test of Concrete?

The Cube Test of Concrete is one of the most important tests done on concrete. It is also known as a test to determine the Compressive Strength of Concrete. This single test is enough to do a quality check on the type of concreting that is being done at the site.

The factors that determine the Compressive Strength of Concrete are Water Cement ratio, Cement Strength, Quality of concrete material, and the quality control that is being done during the production of concrete.

Steps Involved in Cube Test

The steps involved in conducting the cube test for concrete are –

• The Cube Test of Concrete is one of the most important tests done on concrete. It is also known as a test to determine the Compressive Strength of Concrete. This single test is enough to do a quality check on the type of concreting that is being done at the site.
• The factors that determine the Compressive Strength of Concrete are Water Cement ratio, Cement Strength, Quality of concrete material, and the quality control that is being done during the production of concrete.
• The steps involved in conducting the cube test for concrete are –
• A cube of 15cmx15 cmx15cm is cast in a cubical mold with aggregate. It is made compact and densely filled so as to avoid any voids.
• After 24 hours these cubes are removed from the mold and cured under water. The edges must be smooth before they are inserted in water for curing.
• These cube samples are tested after 7 days of curing or after 28 days of curing.
• Compression testing machines test the samples by gradually applying load till the specimen fails. At the failing point, the compressive strength of the Concrete is determined.
