what"s the formula to find the quantity (consumption) of cement,sand,aggregate for 1m3(1:2:4)..

Answer / prakash kale

for 1m3 conctre --

Take a 52% added dry surface of concrete

1+.52 = 1.52

i.e.
For 1.52 cu.m. concrete
Then
1.52/1+2+4=1.52/7
=.21714
=.22
so.22/.0354 =6.2 bags(1 bag = .0354 cu.m cement)

6.2 bags/cu.m in 1:2:4
Sand--
.22 x 2 =.44 cu.m.

Answer / mrinal kumar brahma

Mix ratio 1(cement):2(sand):4(aggregate)

For 1m3 concrete:

1.51(constant)/(Sum of ratio, i.e 1+2+4=7)=0.216

For cement= 0.216x28.57(constant)=6.2 bag

For sand=0.216x2(sand ratio)=0.43 m3

For aggregate=0.216x4(aggregate ratio)=0.86 m3

what"s the formula to find the quantity (consumption) of cement,sand,aggregate for 1m3(1:2:4)..

Answer / vishal rana

Ratio=1:2:4(cement:fine
agg.:coarse agg.)
Sum of the ratio=1+2+4=7.

Total dry mortar for 1cum
cement conc.=1.54(it is fixed)
There for=1.54/7=.22cum

Then quantiy of,cement=.22 into
28.8=6.24 bags.

Sand=.22 into 2(ratio of
sand)=.44cu m.
Aggregate(shingle or bajri)=.22
into 4=.88 cu m.

Materialr for 1cum cement conc.
1:2:4.
Cement=6.24bags
Sand= 0.44cum
Agg.=0.88cum

Answer / ajay kumar pal.(j.e)

for finding the total value of

take 1.52/(1+2+4)

=.22
hence total qty of cement .22*1= .22cum
cement= .22/.0354 = 6.2 bags of cement
sand = .22*2 = .44cum

Aggr =.22*4 =.88cum

what"s the formula to find the quantity (consumption) of cement,sand,aggregate for 1m3(1:2:4)..

Answer / ranjithkumar.t

M15= 1:2:4 (for 1 m^3)

1m^3 = 1440kg, 1 bag = 50 kg

so, 1m^3 bags=1440/50
             = 28.8 bags 

   Cement = 1/7*1.52*28.8
          = 6.25 bags 

   Sand   = 2/7*1.52
          = 0.434 cubic meter

Aggregate = 4/7*1.52
          = 0.868 cubic meter

what"s the formula to find the quantity (consumption) of cement,sand,aggregate for 1m3(1:2:4)..

Answer / vigneshwaran s

Generally its easy to find it.

Find Total Parts = (1+2+4)=7 Parts.

For 1 cu.m of concrete the total parts = 1.57

Unit weight of cement = 1440 kgs

Cement = (1440/7)*1.57 = 322.97/50kgs = 6.46bags.

1 bag cement= 1.25cft

Sand = 6.46*1.25 = 8.075 cft*2 =16.15 cft

Aggregate = 8.075 cft*4 =32.3 cft.

Thats all...

Result:
Cement = 6.46 bags
Sand = 16.15 cft
Aggregate = 32.3 cft.
