Answer / mehar

For example take m15 grade of concrete.. It's ratio 1:2:4
1+2+4 =7
So cement having 1 m3 wet volume.
But dry vol= wet volume x1. 54 m3(45-55 % of dry volume)
Wt of cement =(1x1.54x1440) /7 = 312kg
Convert to bags = 312/50 = 6.25 bags
So for 1m3 of concrete work of m15 grade comcrete nearly 6.5 bags of cement if required..

Answer / subash chandran t

let us consider the concrete to be M25
Mix ratio- 1:1:2
total volume= 1 m3
volume of cement = (1/(1+1+2))x volume of cube = (1/4)x1
volume of cement = 0.25 m3
density of cement=1440 kg/m3
quantity of cement= 0.25x1440 =360kg

Answer / khan.altaf786@gmail.com

Mass of one bag = 50kg

Density of cement = 1400 kg/m3 [1]

Volume of one bag of cement = 50 / 1400 = 0.035714 m3

No. of bags in 1m3 = 1 / 0.035714 = 28 bags

1)What is Suggested type of cement for concreting at water, for mass concreting and where the chaces of gettin attucked by salt? 2)How many types of camber? 3)why we always preffer short column in case of residential building? 4) Is there any advantages between the use of One way slab & two way slab? 5)What shoul be the % of steel for R. C. C. perpose based on volume & area ?
