What is the test procedure for a concrete cube?

Question

Accepted Answer

Concrete cubes are tested by casting them, curing them, and then crushing them to determine their strength.

Prepare the concrete mix according to specifications.
Cast the concrete into cube molds and compact it properly.
Cure the cubes in a water tank or under wet burlap for a specified period.
After curing, remove the cubes from the molds and allow them to dry.
Place the cubes in a compression testing machine and gradually apply load until failure.
Record the maximum load at failure and calculate the compressive strength.
Repeat the test for multiple cubes to ensure accuracy.

Accepted Answer

The test is taken via. Universal testing machine as cube size is taken 150mmx150mm×150mm size specify as per cube mould set the cube in properly in UTM machine and applied load by manually or by electrically and note down the reading if cube fails at perticular load for example cube fails 800kn load that the compressive strength is calculate applied load/ cross-section area of cube mould i.e =800/(150x150)=35.55mpa.
