Answer Posted / sumathi lakshmanan

eg:1:3:6(M10)nominal mix ratio(bcoz size of coarse aggregate is 45mm) for 2 cub.m of PCC
Req:
1)PCC unit weight = 2400kg/cub.m
2)sum of ratio = 1+3+6=10
Procedure:
(1/10)*2*2400 (i.e) (ratio of cement/sum of ratio)*cub.m of PCC*unit weight of PCC =480kg of cement (9.6 or 10bags)
Therefore sand=480*3=1440kgs
Coarse agg(45mm) = 480*6=2880kgs

In an aggregate blending plant, water is sprayed before blending is performed. If the fine content in aggregate is as high as 25 %, will not the fines form into lumps / balls and distribution will not be uniform ? Further, the fines will stick onto the interior of pug mill and its content will be low. The mixed material is stockpiled for weeks / months before use. Will it not be better that blending is done in dry condition, and water will be added only during compaction at site. Please forward your comments and suggestions.
