Cement 7.5 bag

Sand 0.5 M3

Aggregate o.85 M3

Answer / engineer harry mrar

403kg cement
.42cum sand
.84 aggregate
181 liter water

Answer / ashok sakhare

M20 ratio is 1:1.5:3

(i)Total motor wet = 1+1.5+3= 5.5
(a) Volume of aggregate = 35.5*1.57= 0.856m3 Dry motor/ Cum
(b) volume of sand =1.5/5.5*1.57= 0.3
428m3/ Cum ( Dry motor)
(c) volume of cement =1/5.5*1.57 =( Dry cement) 0.285m3*1440=399 kg.
399/50kg= 7.99bags/Cum

(note: 1.57 for 1m3 Dry motor)

Answer / muzammil ahmed

m20=1:1.5:3=5.5, dry mix for im3 is 1.57
1.57/5.5=0.285x30 = 8.5bags OR
=0.285x1500=428.18kg/50=8.55bags(cement)
=0.285x1.5 =0.427x35.28=15cft
=0.285x3 =0.855x35.28=31cft

M20 ratio is 1:1.5:3( TAKE 20mm aggregate)

(i)add ratio= 1+1.5+3= 5.5

(a) volume of aggregate = 1\7*1.57 = 0.22m3
(b) volume of sand =1.5/7*1.57= 0.33m3
(c) volume of cement =3/7*1.57 = 0.67m3*1440=964 kg.
