15O mm cylinder strength (f'c)will be 80% in value for the
150mm Cubes(fcu) (in general). e.g. if fcu =50MPA for same
concret f'c = 40MPa.
But conversion of cylinder strength to cube strength is
very complex. It depends on cylider dia, and height etc.

In ACI 318, the relation curve is given for ready reference.

Answer / gowthami gajula

The compressive strength of cube or cylinder is depends on
slendernwss ratio and volume.. as the slenderness ratio
increases strength decreases and volume increases strength
decrease

Answer / ravi selvan

The compressive strength of concrete is depends on the ares
of concrete. m20 concrete means 20n/cm2 -area of square
cube is=15cmx15cm=225cm2 that means ,the strength of m20
concrete cube is 20x225=4500N (OR)450 KG... like that
cylinder area and cube area should be cakculated

Answer / er. mohit sharma

i think if the volume of concrete is increase then
strength is also increase becausse M20 means 20N/mm2 so if
we increase the area of surface strength is also increase

Answer / sjtbehera

The Specimen Size and shape effects on the compressive
strength. Diffrent size of cylinder of diffrent height nave
diffrence compressive strength. the diffrence between these
cubes is we don't compare these strength result with the IS
standard which has been tested in a standard cube.

providing, fixing, removal of pockets of size 100*150*300mm to 500*600*1000mm for foundation. the shuttering material used for making &fixing of pockets shall be removed by the contractor without damaged to pockets. if any damage occurred, the same shall be rectified by the contractor is to handover the pockets to forge shop engineer with proper marking of centre lines, levels etc.

A 16 pile group, consisting of diameter concrete piles, were cast in situ in a clayey soil whose unconfined compressive strength is 1100 psf. Each pile is 60 ft long and the pile spacing is 2.5 times the pile diameter.The water table is at the ground surface and saturated unit weight of the clay is 118 lb/cu.ft. using a factor of safety 3 and a reduction factor =0.45, compute the allowable capacity of the piles acting as individuals
