How can we conduct concrete cube test.

Question

Accepted Answer

Concrete cube test is conducted to measure the compressive strength of concrete.

Prepare the concrete cubes by using a standard mix design.
Fill the cube moulds with freshly mixed concrete in layers.
Compact the concrete using a vibrating table or a vibrating poker.
Smooth the surface of the cubes using a trowel.
Label each cube with relevant information like date, mix design, etc.
Cure the cubes in a curing tank or moist environment for a specified period.
After the curing period, remove the cubes from the moulds.
Measure the dimensions of the cubes using a caliper or ruler.
Place the cubes in a compression testing machine.
Apply a gradually increasing load until the cubes fail.
Record the maximum load applied and the corresponding cube failure load.
Calculate the compressive strength of the cubes using the formula.
Repeat the test for multiple cubes to ensure accuracy and reliability.

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.
