I general to calculate weight of cement you need to know
the ratio.Once ratio is known to you the you can calculate
by using this simple formulae

1.52 / Mix proportion will give you weight of cement per
cum from this you calculate weight of cement in kg(1 Cum =
1440 kg)

Ex(for 1:2:4, 1.52/(1+2+4)=0.1428 cum or 205 kg.

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
