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=316.82 kgs/cum
sand = 0.44*1750=770kgs/cum
metal = 0.88*2000=1760kgs/cum
