Answer
# 1

Here volume is (1 cement bag=1.25 cu.ft)
cement 1 1.25 cu.ft
sand 2 2.50 cu.ft
metal 4 5.00 cu.ft
-----------
8.75 cu.ft total volume

Answer
# 2

The ratio is 1:2:4, so total ratio is 1+2+4=7
considering 1cum.
cement = (1 x 15.4)/7= 2.2 cum
= 2.2/.347=6.3bags
sand=2.2x2=4.4cum
metal=2.2x4=8.8cum

Answer
# 3

For M15 - 1:2:4

Consider 1 cumec

Summation of M15 Proportion is 1+2+4 = 7

Quantities:
Cement = 1(cumec)/7(summation)
= 0.1428 cumec
= 0.1428/0.0347
= 4.11 = 5 bags

Sand = 4.11 * 2 = 8.22 cumec

Aggregate = 4.11 * 4 = 16.44 cumec

For W/C = 0.45 (Assumed)

Water = 0.45 * 4.11 = 1.85 ltrs

Answer

Consider for 1CUM of concrete is to be prepare,For that

M15 is a nominal mix, its proportion is 1:2:4

for 1cum of final mix(Dence) is required, 1.50 to 1.55 Cum
of loose ingredients with the required proportion we want
to add.

Based on that take avg of 1.50 & 1.55 is 1.52

Total proportion = 1+2+4 = 7

For Cement Qty = 1.52/7=0.217 Cum of cement required to
prepare 1Cum of M15 concrete.But cement is always taken in
Weight.For that the unit weight of cement is 1440 KG/Cum
Total cement required = 0.217x1440= 312.68 Kgs.

Sand = 0.217 x 2 =0.434 Cum

Metal or Aggregate = 0.217 x 4 =0.868 Cum.

DETAILS:

cement = 1,
sand = 2
metal = 4
so wat is the ratio we want mixing (1:2:4)=1+2+4=7
7 is mixing propotion
volume of wet cement conceret is 1.54 to 1.57

unit weigth of cement is 1440kg/cum

one bag of cement =50/1440=0.034722 cum

solution : cement = 1.54/7=0.22
0.22/0.03472=6.33 bags
one bag of cement = 50kgs
=6.33*50kgs=316.82 kgs

solution of sand = 0.22*2=0.44cum

2 is the mixing of propotion

soolution of metal = 0.22*4=0.88cum

4 is the mixing of propotion

say i cum of cement conceret 1:2:4 ratio

cement = 6.33 bags

sand = 0.46 cums

metal = 0.88 cums

this is one type of solution

unit weight of cement is 1440kg/cum
sand 1660 to 1800kg/cum
Unit weight of metal is 1630kg to 2000kg/cum

so cenment = 1.54/7=0.22
0.22*1440=316.8 kgs/cum
sand = 0.22*1750=385kgs/cum

metal = 0.22*2000=440kgs/cum

Answer
# 6

Sample = 1 M3 of M15 i.e 1:2:4

Aggregate = 20mm

Final Mixture and Loose Aggregate Ratio is 1.57(in practies)

SO CALCULATION FOR 1:2:4

1+2+4=7

CEMENT = (1.57/7)X1=0.2242 M3X1440=322.8Kg= 6.45 Bags
RIVER SAND= (1.57/7)X2=0.4485 M3X35.314 = 15.83 Cft
AGGREGATE = (1.57/7)X4=0.8971 M3X35.314 = 31.68 Cft

Answer
# 10

ratio is 1:2:4 sum is equle 7
1 bag cement is equle to 1.25
total quantity resum is 200 cft
for cement bags ;200 divide bt ratio which is 7 answer is 28.57
than
28.58 multiply by 1 wich is first figure of ratio
than divided by 1.25 which is volume of 1 cement bag
the answer is calkled cement bags
example
cement bags ;200/7=28.57*1/1.25=22.85 bags
for sand 200/7=28.57*2=57.14 cft
for crash 200/7=28.57*4=114.25 cft
