1.2 metric tons equals 1 cubic meter of Fly ash (one of the residues of coal combustion).
For 1 meter cube of brick work, you would need approximately 13 bags of cement.
Input : 1. Thickness of plastering 12mm (0.012m). 2. Cement sand ratio 1:6Suppose we require to plaster 100sqmThen 100x0.012=1.2m3 of mortar is requiredFor 1:6 ratio,Cement requirement will be= 1.2 x 1/7 (one part of cement in mortar) = 0.1714m3 cement,Since cement goes in the voids of sand we nead 20% extra material = 1.20 x 0.1714 = 0.2056 cum.Now add 20% extra to cover uneven surface of brick work = 1.2 x 0.2056 = 0.2468 cu. m of cement.Now for 50 kg of cement = 0.0345cum, therefore = 0.2468 / 0.0345 = 7 bag of cement.Sandrequirement will be= 1.2 x 6/7 (sixth part of sand in mortar) = 1.0285 m3 sandNow add 20% extra to cover uneven surface of brick work = 1.2 x1.0285= 1.2343 cu. m of sand.Convert sand in MT multiply is by 1.602 (specific gravity) 1.2343 x 1.602 = 1.9773 MT
For M20 grade concrete, the mix proportion is 1:1.5:3 (cement:sand:coarse aggregates). If we consider a volume of 1 cubic meter, approximately 320 kg of cement would be needed.
How many cubic meters in 1 cement bag of 50kgs
7 cement bags per 1 cubic meter of concrete......
one cubic meter of concrete equals 30 bags(approximately) The exact answer is 28.8 bags of 50kg cement bags. Typical Portland Cement has a density of 94 lbs/cubic foot, which translates to 1505 kg / cubic meter. So, divide 1505 kg by the weight of a "bag" of cement in kg. --------------------------------------------------------------------------------------------- Seems to be perhaps a little confusion here between concrete and cement. Cement is the powder we mix with aggregate to make concrete. Cement varies in density as much as 100%, i.e. it can double in density. From the above URL one 94lb bag is taken to be 1 cu ft for building purposes. 1 cu metre = 35.3146667 cu ft and therefore 1 cu meter of CEMENT is that many 94lb (42kg) bags. Hence the answer for how many Cement bags in 1 cu m = 35.3 94lb bags. It would make more sense if the query was directed towards finding how many bags of cement are required for 1 cu meter of CONCRETE. This depends, of course, on the chosen concrete mix. They vary widely. A most common mix is 1:2:3 - 1 part cement, 2 parts sand, three parts aggregate all by volume. In concrete making the dry ingredients shrink during the process as they compact together. It is found necessary to commence with 1.6 cu m of dry material to finish with 1 cu meter of concrete. 1.6 cu m = 56.5034 cu ft of which the cement portion should be 1/6 for a 1:2:3 mix. 56.5034/6 = 9.4172 cu ft and therefore 9.4172 1 cu ft, 94lb or 42kg bags are required or round about 20 of the usual household DIY worker's 20kg bags here in Australia. Hence the answer for how many bags of cement to make 1 cu m of (1:2:3) concrete is 20 20kg bags. These answers are not precise because of the nature of cement. Refer again to the Portland Cement Association website and their remarks on density.
7 bags cement
1.4 = D / D (water) 1.4 = D / 1 tonne/cu meter 1.4 tonne/cu meter = D 1.4 tonne/cu meter * 1 cu meter/ 264.17 gal = D D = 369.8 tonne / gal So, 0.0027 gal in tonne
15 milligrams
Depends how big the bag is
1 cu. metre = 1000 litres
1 ft3 = 0.02832 m3
~ 1 cu. ft.
It would depend on how big the bag of cement is. 1 foot bags will be more in the cubic meter than 2 feet.
0.3 cubic meter cement mortar consumes.
