28/11/2019 · Try to use aggregate to cement ratios of 6:1, 8:1 and 10:1 (230 litres, 300 litres and 380 litres of aggregate per 50kg bag of cement). For each ratio or combination, mix a batch of concrete with water and use the brick moulding machine to make some test bricks. This way, you can find the perfect mixture for your needs.
So, Sand required = *1600 = 115 kgs. and Aggregate required = *1450 = 209 kgs. Considering water/cement (W/C) ratio of We can also arrive at the Water required = 50* = kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and kgs of water to produce M20 grade concrete.
Two grades of concrete M20 and M25 having nominal mix proportion of 1::3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%.
