Question
HOW TO CALCULATE CEMENT REQUIRED FOR M20,M5 GRADE
 Question Submitted By :: Civil-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
for M20 grade ratio is (1:1.5:3)
we consider for 10m3
add 50% for shrinkage & wastage
then it is 10+5=15m3
cement= 15/1+1.5+3 *1
= 2.72m3
for no. of cement bags = 2.72/0.0347
= 78.38 no.
= 79bags for(10m3)
so that for 1 m3 it is around 8 bags..........

Answer
# 2
for M5 it is 2.5 to 2.6bags/Cum
the proportion is based on volume ie (1:5:10)

for M20 cement required is 8.01 bags/Cum approximate (as it
Design Mix it differ)

Answer
# 3
For M20 concrete, The ratio of the mix is 1:1.5:3 (Nominal mix)
The total parts is 1+1.5+3 =5.5
Part of the cement is = 1/5.5
The total volume raw material for 1m3 of mixed concrete practically =1.57m3
Unit weight of cement =1440kg
Weight of cement per bag = 50kg

Now the calculation is =1/5.5X1.57X1440
= 411kg
In terms bags per m3 of conctrete is 411/50 = 8.22bags
 
Is This Answer Correct ?    19 Yes 6 No

Answer
# 4
ANY RCC 1 M3 CONCRETE REQUIRED 20 MM METAL- 0.9M3

M20 MIX- 1: 1.5 : 3

3 PART OF METAL - 0.9 M3

1.5 PART OF SAND - 0.45 M3

1 PART OF CEMENT - 0.45 / 1.5

- 0.3 M3
1 M3 CEMENT - 1440 KG
0.3 M3 CEMENT - 1440*0.3

-432 KG = 8.64 BAGS

Answer
# 5
While designing the mix, we shall take various paramenters
such as; workability, exposure, quality control etc., into
cognizance. If we consider the workability as 0.8, exposure
is moderate, QC as good, FA is in Zone-III, then quantum of
Cement required for 1cum of M20 concrete is; 53Gr OPC-465
kg, CA-1184.82 kg,FA-495.77 kg and water 186 lt.
 
Is This Answer Correct ?    0 Yes 7 No

Answer
# 6
for M20 grade of concrete
Ratio 1:1.5:3
(i.e) cement : coarse aggregate : Fine Aggregate.
( jally ) ( sand )
1cubic metre cement = 1440KG
In the concrete 0.45% of the sand ratio is utilised for
cement.so for M20
= 0.45/3 X 1440
=0.15 X 1440
= 216Kg/cubicmetre
= 4.32Bags of cement/cubicmetre of concrete
 
Is This Answer Correct ?    3 Yes 15 No
