Pcc or cement concrete 1 : 2 : 4 = 5m^3/day/person.

For 1 cum how many bag of cement?
if 1:2:4 ratio
1 cum =6 bags
that means
5 cum= 30 bags
Can do this work with mason perday? Anyone, please explain me.

1:2:4 rcc work = 3.25 m3,
Cement concrete = 5m3 per mason.
Here, asked about " cement concrete" so answer 5 m3 per mason.
Cement concrete = 5m3 per mason.

That is cement concrete so the answer is 5 m^3.
If they use reinforced cement concrete so the answer will be 3 m^3.
If they use reinforced cement concrete so the answer will be 3 m^3.

For 10 m3 of cement concrete work.
Masons needed are 2.
Hence there is one mason, then the quantity in m3 is 5m3.

100 M3 for 13 masons.
Per one mason =100/13=7.69m3 dry concrete,
Dry concrete= 1.52*wet concrete,
So wet = 7.69/1.52= 5 m3.

1:2:4 it means M15 grade it means work in foundation which 5m^3 per mason per day.

1 : 1.5 : 3 material and grade is different. But labour constant is same. So, the answer 5.

1 : 2 : 4 concrete, 1m3 need Labour constant.
Mixing concrete --------> 3.00 hour/m3.
Lifting and carrying concrete --------> 1.20 hour/m3.
c.compacting concrete --------> 0.80 hour/m3.
d.leveling surface of concrete --------> 0.10 hour/m3.
Total=(3+1.2+0.8+0.1) = 5.
