Answer Posted / sjtbehera
In the case M30 concrete we calculating by design mix.but
incase of norminal mix we can use 1:1:2.
calculating cement, sand and concrete.
toal ratio=1+1+2=4
cement = 15.4/4=3.85cum=11bags
sand=3.85*1=3.85 cum
chips=3.85*2=7.7 cum
Notes: why we divided 15.4
but it is difficult to acess exactly the amount of each
material recquired to produce 1cum.of wet concrete when
deposite in place.
to find out volumes of cement sand & coarse aggregate
divided a numerical no. 15.4 variable up to 15.7 according
to proportioning and water cement ratio by the summation of
the proporation of the ingrediants used and then multiply
the result thus obtained their respective srength of
proportion.
