dry volume of concrete : 154 quantity of cement required for 1 cum of concrete is = dry volume of concrete * per 1 cubic foot what is the concrete usage of . gravel calculator. the gravel calculator takes account of the by transforming the volume as follows: metric - tons: - 1 cubic feet = 0 total required gravel mass in lbs .

concrete mix estimation. 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.

how to calculate quantities of cement sand and aggregate for nominal concrete mix 1:2:4 ? mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability strength setting time and durability.

product quantity calculator our quantity calculator will help you calculate the amount of tonnes you require for your project. the results from this gravel calculator are only to be used as a rough guide as exact conversions depend on many factors.

a driveway should have a depth of 6-8″ of gravel. the formula to find volume is length × width × depth. to find the cubic yards of gravel needed multiply the width in yards by the length in yards by the depth in yards. calculate how many tons of gravel are needed for a driveway. gravel is sometimes sold by the ton instead of the cubic yard.

a cubic meter of typical gravel weighs 1680 kilograms 1.68 tonnes. a square meter of gravel with a depth of 5 cm weighs about 84 kg or 0.084 tonnes. the numbers are obtained using this gravel calculator.

how our calculator works. to determine the area of a site in cubic yards the converted measurements are multiplied together. our calculator uses the formula to convert and calculate: width/3 x length/3 x depth/36 = amount of gravel in cubic yards. since our calculator takes the effort out of finding out how much gravel you need

these concrete calculators provide the required quantities of cement and all-in ballast or cement sharp sand and gravel required to give a defined volume of finished concrete. both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete.

use this calculator to determine how much sand aggregate gravel and cement is required for mixing on site a given area of concrete 1:2:4 ratio . please enter the dimensions in the white fields below and click calculate to display the results.

these concrete calculators provide the required quantities of cement and all-in ballast or cement sharp sand and gravel required to give a defined volume of finished concrete. both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete.

if i'm going to pour concrete on 2 columns with size .3m x .3m x 3m height. how many cement sand and gravel do i need. simply compute the total volume = .3x.3x3 x 2columns = .54 cu.m. for class a mixture cv concrete volume x 7.85 = no. of cement = .54x7.85 = 4.2 or say 5 bags

concrete mix quantities calculation let us consider m20 concrete mix - 1:1.5:3 total volume = 1 1.5 3 = 5.5 consider wet volume = 1m^3 dry volume =1.54x1 =1.54 m^3 54% increases cement: quantity of cement in cubic metres = 1x1.54/5.5 = 0.28m^3

the formula is 36 x 9 x .25 = 81 cubic feet of gravel. to determine how many cubic yards are needed for the job divide 81 by 27 which is the number of cubic feet in a yard to arrive at 3 cubic yards for the project.

considering a concrete mix proportion by volume of 1:2:4. i.e. cement: fine aggregate sand : coarse aggregate is in the ratio of 1:2:4 by volume. cement required = 01 bag = 50 kg 36 liters or 0.036 cum. fine aggregate required = 2*0.036 0.07 cum = 0.072*1600 = 115 kg. coarse aggregate required = 4*0.036 0.14 cum =0.144*1450 = 209 kg

quantity of materials such as cement sand coarse aggregates and water required per cubic meter of concrete and mortar for different mix proportions varies with the mix design of the concrete and mortar respectively.

let our gravel needed calculator take the work out of helping you to determine the exact amount of gravel you need to purchase from the store. our calculator converts your measurements into yards and gives you the answer you need in cubic yards making your job of purchasing the gravel easier.

the quantities of materials for 1 m3 of concrete production can be calculated as follows: the weight of cement required = 7.29 x 50 = 364.5 kg. weight of fine aggregate sand = 1.5 x 364.5 = 546.75 kg. weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.
