What is the volume of sand in per cubic meter if we have a design mix of concrete is 1:2:4 (by volume).

Answer Posted / shamsideen mohammed sakwa

1:2:4=7, let's assume the area to be plastered is 100m2
0.012*100=1.2m3
2/7*1.2=0.3428572
You divide your ans by the volume of the tipper per trip,
0.3428572/3.82m3 per single trip
=1.3097145
Approximately = 1.31

As per Kandal suggestions, we have implemented rolling starts on 140 (+/- 5) degrees and we kept 3 rollars to complete the rolling before falling 125 degrees and the Aggregate AIV is below 22. But When the DBM bed is being rolled 3rd high viabration, (Before 1 plain & low ,2 high Viabrations), the aggregate is getting sharp edge agg. projections are damaged. As the literature is said that, the VG-30 Grade having better control the temp. susceptibility than Penetration grade. if so we could not get this problem at site. But we are facing on site. let me know.
