Quantity of cement In Cubic metre = 1 x 1.54 / 5.5 = 0.28 m 3 . Quantity of cement in kg = 1 x 1.54/5.5 x 1440 = 403.2 kg. Therefore, Density of cement = 1440 kg/ m 3 . Number of cement bags required = 403.2/50 = 8.064 bags. ... 8.064 bags of cement required for 1 cu.m of M20 grade concrete. 630 kg of Sand required for 1 cu.m of M20 grade ...
Aug 12, 2013· So 0.8 cube meters / 0.0169902 = 47.08 or 48 bags weighting 36.3 kg / 6 = 8 bags cement, 580.8 kg sand & 870 kg gravel. Seeing you'll probably have wastage and you'll probably only be able to buy 1 or 1/2 tone loads, you might as well buy 9 bags and a tone of each of the sand and gravel.
Jun 04, 2013· Talil is going to make some concrete mix. He needs to mix cement, sand and gravel . in the ratio 1 : 3 : 5 by weight. Talil wants to make 180 kg of concrete mix. Talil needs 20 kg of cement, 60 kg of sand. and 100 kg of gravel. Talil has. 15 kg of cement, 85 kg of sand and. 100 kg of gravel.

Aug 03, 2018· Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY; Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened.The strength concrete is inversely proportional to the water/cement ratio.
18) Talil is going to make some concrete mix. He needs to mix cement, sand and gravel in the ratio 1 : 3 : 5 by weight. Talil wants to make 180 kg of concrete mix. Talil has 15 kg of cement, 85 kg of sand, 100 kg of gravel. Does Talil have enough cement, sand and gravel to make the concrete mix?

With a 1:3:6 mix for 100 cubic meter of concrete you would need 420 x 50kg bags of cement, 56 cubic meters of fine aggregate (sand and gravel passing through a 5mm sieve) and 79 cubic metres of coarse aggregate (gravel retained by a 5mm sieve).
Please note that the cement in bags can not weigh 50 kg, as it is written. Trust, but verify. How much cement you poured the better to check. Please note that the cost of sand and gravel is specified in the program for 1 ton. Vendors also announced a price per cubic meter of sand or gravel or gravel. Proportion of sand depends on its origin ...

Sep 17, 2013· Cement. 1 x 20 =20 kg. so not enough of cement. Sand. 3 x 20=60kg. so enough sand. Gravel. 5 x 20 =100kg. so enough gravel. Talli have enough sand and gravel to make the concrete mix but there is not enough of sand
Mar 18, 2017· Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. 1.Cement = 6 bags ...
So, the weight of concrete produced with 1 Bag of cement (50 Kgs) =50 kg + 115 kg + 209 kg + 27.5 kg = 401.5 kg ~ 400 kgs. Considering concrete density = 2400 kg/cum, One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4

Table for Quantity of Cement, Sand, Aggregate, Water required for Different grades of ...
Assume water/cement ratio of 0.45 BY WEIGHT for a slab mix, so the water volume will be about 1.4 parts by volume, or 1.4 water: 1 cement: 2 sand: 3 coarse aggregates, 7.4 parts total. For 0.15 m^3, you need about 0.15/7.4 or about 0.021 m^3 of cement. That will be about 66 KG of cement, or a little more than one 50-kg sack (a common size).
