Answer / sjtbehera

all are 1:1:2

Answer / shanmugam

m7.5 = 1:5:10
m10 = 1:4:8
m15 = 1:3:6
m20 = 1:2:4
m25 = 1:1.5:3
m30 = 1:1:2

i think there is a ratio for m35= 1:1:1
and after that only the mix design starts........

In IS:456-2000 the workability of concrete is given in mm (slump)in cl.7.1. In IS:10262-1982, cl.3.3.4 & table-6 says +/- 3 percent adjustment is required in the quantity of water (calculated as per table-4 or 5), for each increase or decrease in the value of compacting factor (i.e. workability of concrete) by 0.1. How it is possible to calculate the exact quantity of water required for a particular grade of concrete? What is the relation between Slump & Compacting factor of concrete?
