This calculator is intended for approximate guidance. Working with Concrete Tips Hand Mixing Only use clean water, sand and gravel. Aim for a mix of 1 part cement,
An 80pound bag of concrete makes cubic feet. A cubic foot of any material is enough to fill a box that is 1 foot wide, 1 foot tall and 1 foot long. In order to determine the volume of concrete required for a project, a worker must determine the surface area and thickness of the concrete.
Dec 14, 2018· Quikrete''s Concrete Mix yield''s about .15 cubic feet for every 20 pounds of mix, so a 40pound bag yields .30 cubic feet, 60 pounds of concrete mix yields .45 cubic feet and an 80pound bag .
Manufacturers rate the size of tiltingdrum concrete mixers by the volume of the mixer drum. A 6cubicfoot cement mixer holds 6 cubic feet of material if positioned upright and filled to the brim. The maximum working capacity of the mixer falls far short of that. Sixcubicfoot mixers can mix only 3.

This standard concrete mix (used for most premix applications) weighs about 133 pounds per cubic foot of concrete, so a cubic yard (which contains 27 cubic feet) will weigh in at about 3,600 pounds. With the given mix ratio, cured concrete is about 22 percent cement by weight.
An 80pound bag of concrete yields cubic feet of wet concrete when mixed with the proper amount of water. Concrete consists of portland cement, sand, stone, gravel and additives that make the substance cure when it dries. An 80pound bag needs about 6 pints of water to mix properly.
Most concrete suppliers will not sell fractions of a yard of concrete, though it is worth asking about. So, in this example, you would want to buy bags. Using the table below, you would need to buy at least eight 80 lb. bags and one 40 lb. bag (yielding a total of cubic feet) of concrete to allow enough for extra.
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).
Y = yield of concrete produced per 94pound bag of cement, in cubic feet; S = volume of concrete produced per batch in cubic f e e t ; N = number of bags of cement in the batch. Re l a t i v e yield, which is the ratio of actual volume of c o n c r ete obtained to the volume as designed for the batch, can be calculated with the following form u ...
Dec 05, 2017· For 100 cubic feet concrete dry material required 100+100*54%=154 cubic feet or 154/(**) [1m= feet] = cubic meter If this is M20 concrete (1::3) Cement required =/(1++3)×1= cubic meter. Density of PPC=1440Kg/cu...
Fa = Mass of fine aggregates. Ca = Mass of coarse aggregates. S c, S fa and S ca are the specific gravities of cement, fine aggregates and coarse aggregates respectively.. The air content has been ignored in this calculation. This method of calculation for quantities of materials for concrete takes into account the mix proportions from design mix or nominal mixes for structural strength and ...
In the step 3 of "How To Calculate Quantities Of Cement, Sand And Aggregate For Nominal Concrete Mix (1:2:4)" you have calculated that: 01 cum of concrete will require Cement required = 1/ = Bags ~ 6 Bags Sand required = 115/ = 688 Kgs or cft Aggregate required = 209/ = 1251 kgs or cft

Quantity of aggregate in cubic feet = 3 x / x = Water: For M20, 30 liters of water per 50kg cement . Total amount of water required = 30 x / 50 = litre. bags of cement required for 1 of M20 grade concrete. 630 kg of Sand required for 1 of M20 grade concrete.
A cubic yard is 27 cubic feet. A 90 lb bag = cubic feet of finished concrete. 27 divided by = 40 So the answer is 40 bags of 90 lb mix = 1 cubic yard. (I''d buy one more bag to cover any spillage while mixing or pouring it into the forms, or possibly uneven surface area greater than expected).
Learn how to calculate how much concrete is needed for projects around the home and how many bags of concrete mix to buy. Calculate the concrete volume in cubic feet and convert that volume into bags depending on the size bag available or the weight you are able to carry.
