9*9 1:4:8 ratio using how to calculate the material for
40mm aggregate ,cement &sand please tell me answer

Answer Posted / sravan875

1:4:8 Ratio means 1%cement,4%aggregate,8%sand.
cement percentage--1/13=0.0769231cum.
aggregate %---4*0.0769...=0.3076924cum.
Sand % ----8*0.0169...=0.6153848cum..

Cement=0.0769*2370kg/cum (unit weight of concrete)=182.30775kg

40mm Aggregate=(density 1950kg/cum).
aggregate needed=0.3076924*1950=600.00kg of aggregate

Sand density(dry,packed)---1600-1900kg/cum
sand(dry,packed)-0.6153848*1750=1076.9234 Kg of sand is required.

Cement=182.3 Kgs
Aggregate=600Kgs
Sand=1077 Kgs

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.
