What is different between Artesian well and Flowing well?
Mostly the ratio of 1:1.5:3 is used for M20 grade of concrete So, Volume of dry concrete = 1.54 to 1.57 times volume of wet concrete Assume, 1cum of concrete work ratio sum = 1+1.5+3 = 5.5 shrinkage or safety factor = 1.57 Total volume of wet concrete required is = 1.57cum Volume of broken stone reqRead more
Mostly the ratio of 1:1.5:3 is used for M20 grade of concrete
So, Volume of dry concrete = 1.54 to 1.57 times volume of wet concrete
Assume, 1cum of concrete work ratio sum = 1+1.5+3 = 5.5
shrinkage or safety factor = 1.57
Total volume of wet concrete required is = 1.57cum
Volume of broken stone require = (3/5.5) * 1.57 = 0.856 m3
Volume of sand require = (1.5/5.5) * 1.57 = 0.471 m3
Volume of cement = (1/5.5) * 1.57 = 0.285 m3
=0.285*1440 =411 kg
For 1 m3 of M20 (1:1.5:3)
Broken stone = 0.856 m3
Sand = 0.472 m3
Cement = 8.22 bag
Therefore,
8 bag of cement is required for 1cum of concrete work in M20

Artesian well: When the well is excavated in the confined aquifer, and the water in the well reach over the water table but not on the surface of the earth. Such a well known as an artesian well.
Flowing Well: When a well is excavated in the confined aquifer, and the water is flowing over the well or on the surface of well. Such a well called as flowing well.
