Q1. How to check concrete slump
Ans. 
Concrete slump can be checked using a slump cone and measuring the difference in height before and after filling with concrete.
• Prepare the slump cone by wetting it and placing it on a flat, level surface.

• Fill the cone with concrete in three layers, each tamped with a rod 25 times.

• Lift the cone vertically and measure the difference in height between the top of the cone and the displaced concrete.

• The slump value is the d...read more

Q2. How to check concrete cube
Ans. 
To check concrete cube, perform a compression test to determine the strength of the concrete.
• Perform a compression test on the concrete cube using a compression testing machine.

• Calculate the compressive strength of the concrete cube by dividing the maximum load applied to the cube by the cross-sectional area of the cube.

• Compare the compressive strength of the concrete cube with the specified strength in the design mix ...read more
