Slump test is a method to measure the workability of concrete by determining the consistency and stiffness of the mix.

• Slump test involves filling a cone-shaped mold with concrete, then removing the mold and measuring how much the concrete slumps or settles.

• The amount of slump indicates the workability of the concrete mix - higher slump means more workable mix.

• Slump test helps in ensuring that the concrete mix has the r...read more

M30 grade concrete ratio is 1:1:2 (cement:sand:aggregate)

• M30 grade concrete has a ratio of 1:1:2 for cement:sand:aggregate

• This means for every part of cement, there is an equal part of sand and double the part of aggregate

• For example, for 1 cubic meter of M30 concrete, you would need 1 part cement, 1 part sand, and 2 parts aggregate

Slum test is a method used to assess the quality of concrete by observing the flow of concrete through a standard slump cone.

• Slump test is performed by filling a slump cone with freshly mixed concrete, then lifting the cone and measuring the amount of slump or settlement of the concrete.

• The result of the slump test indicates the workability of the concrete mixture, with different slumps corresponding to different level...read more
