Answer Posted / ronak shah
putcube in compressive testing machine, give pressure 140
kg/sqcm/minute.
strength= load/area
if you want to know the solid cube density. take weight of
cube.
forumala;
density=mass/volume=weight of cube/volume of cube
(0.15*0.15*0.15)
ans gives you density of solid concrete.
if you want wet concrete density then take cylinder 10
liter weight of empty cylinder then fill with concrete
weight of concret/volume of cylinder its gives density of
wet concrete.
