what is the procedure to make compressive strength test for
concrete cube in lab
Answer Posted / sjtbehera
to test the compresive strength of concrete, a copmreesive
test machines avaliable in the market. generally pressure
are devlop by hydraulic jack. A cube 22.5 x22.5 square cube
mould ara availabe. this mould will fille up by concrete
and immersed in water 24hrs.. after this cube are test at 7
days and 24 days mould. A pressure gauge is on testing
machines. the mould are keep under pressure and give
pressure when moulds are break. The moment of breaking
mould see the pressure delvop by machines. it is usally

In an aggregate blending plant, water is sprayed before blending is performed. If the fine content in aggregate is as high as 25 %, will not the fines form into lumps / balls and distribution will not be uniform ? Further, the fines will stick onto the interior of pug mill and its content will be low. The mixed material is stockpiled for weeks / months before use. Will it not be better that blending is done in dry condition, and water will be added only during compaction at site. Please forward your comments and suggestions.
