1 CFT 10mm & 20mm aggregate weight in kg
There is around 25 CFT in 1 ton of aggregate/ gravel/ coarse sand. Density of a aggregate/gravel/coarse sand is around 1420kg/m3, it means 1 cubic metre of a aggregate weight is 1420 kg, 1m3= 35.32cft, it means 1.42 tons (1420kg) = 35.32 CFT, hence 1ton (1000kg)= (35.32/1420)×1000 = 25 CFT so there is around 25 CFT in 1 ton of aggregate ...
