Enter Round off answer to next even higher figures. 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, 21/4 part sand and 3 parts aggregate. Mix the dry cement and sand, add water, mix, then add aggregate, and more water as needed.
Quantity Calculator fluidadmin T10:51:04+00:00 If you are unsure how much aggregate you need, use our calculator below. Select your aggregate type, then enter your measurements below.
Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = cum. No. of bags required for 01 cum of concrete = 1/ = bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. = 6 bags = 300 kgs. Aggregate = 115/ = 689 kg
For estimating purposes, you can make about 1 cubic yard of concrete with 5 1/2 94pound bags of cement, 17 cubic feet of sand, and 18 cubic feet of gravel. (It takes about forty 80pound bags of prepackaged materials to make 1 cubic yard of concrete.)
The below image shows quantity of cement, fine aggregate, Coarse aggregate for 1m³ of concrete. I hope it''s clear..
Both concrete calculators make an allowance for the fact that ballast etc losses volume when mixed to make concrete. Two Concrete Calculator are provided for different concrete mixes: General mix 1:5 cement:allin ballast or 1:2½:3½ cement:sharp sand:gravel.
The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = x 50 = kg. Weight of fine aggregate (sand) = x = kg. Weight of coarse aggregate = 3 x = kg. Concrete Calculator: Calculate Quantities of Materials for Concrete
Cement to all in ballast. Help please ! How many 25Kg bags of cement do I need for 1 cubic metre of allinballast when mixing concrete at a ratio of 1:6. hi,what is the calculation of estimating concrete for footings and conrete slab in cubic metre and then into tonne bags of ballast and cement?
These Concrete Calculators provide the required quantities of cement and allin 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. Calculator are provided for a general ...

High strength concrete would be mixed using 1 part cement to 5 parts ballast – this affords the sort of watertight concrete used for building slabs or concrete panels. Mixing 1 part cement to 6 parts ballast creates concrete suitable for driveways, paths and patios, and increasing the ratio to 1:8 gives foundationstrength concrete.
OnSite Concrete calculator. 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. See below for help on concrete.
Dec 21, 2016· Therefore volume of 1 bag cement = 50/1440 = cum. ∴ No. of cement bags required in 1 cubic meter = / = bags. Note: You can use the same formula for calculating cement for other nominal mixes.
Calculate Volume of Square Slab Calculator Use. Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. Enter dimensions in US units (inches or feet) or metric units (centimeters or meters) of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure.
Both concrete calculators make an allowance for the fact that ballast etc losses volume when mixed to make concrete. Two Calculator are provided for different concrete mixes: General mix 1:5 cement:allin ballast or 1:2½:3½ cement:sharp sand:gravel.
Apr 23, 2018· Estimating concrete steps. Steps seem tricky to calculate but are not. If there are three steps leading up to a porch: Use the slab calculator to figure the concrete needed for the porch surface. Use the footing calculator to calculate the sides of the porch and the steps; Here is an example:
General mix 1:5 cement:allin ballast or 1:2½:3½ cement:sharp sand:gravel. and ; Paving mix 1:3½ cement:allin ballast or 1:1½:2½ cement:sharp sand:gravel. Comment: If you are wondering how 1:2½:3½ equals 1:5 ("shouldn''t it be 1:6" I hear someone say), the answer is that there is a lot of space between the individual pieces of gravel ...
Jan 30, 2009· Anybody know a site for working out how much ballast and cement to order for building a concrete base. Be good as well if you could change the mix ratios. I think i need 5:1. but would be handy for other projects too.
Aug 03, 2018· CALCULATION FOR CEMENT QUANTITY; Cement= (1/) x = m 3 ∴ 1 is a part of cement, is sum of ratio Density of Cement is 1440/m 3 = x 1440 = kg We know each bag of cement is 50 kg For Numbers of Bags = /50 = 8 Bags We Know in one bag of cement = CFT For Calculate in CFT (Cubic Feet) = 8 x = Cubic ...
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, m 3 of sand and m 3 of stone aggregate.
Our concrete calculator provides you an easy way to calculate concrete volume and estimated cost of concrete slabs, footers, walls, columns, steps, stairs, curbs and gutters in cubic feet, cubic yards, and cubic meters and inches. It makes your construction project planning and budgeting more accurate.
Apr 20, 2017· You''ll need a bit more than one 1 ton bags of ballast and around 6 bags of cement I reckon. A 1 ton bag is actually around 900Kg ish, so probably 4045 bags at 25kg each is my guess. 1:4 ratio is quite strong, 1:6 would be fine 12 shovels of ballast to 1/2 bag of cement.
Landscape Gravels tons (2,400 2,700 lb.) per cubic yard Washed Gravel tons (2,700 lb.) per cubic yard Washed Limestone tons (2,400 lb.) per cubic yard
When ordering concrete from a redimix supplier, the concrete comes in cubic yards. If you tell the Dispatcher your dimensions and thickness, he can figure the concrete for you as well. It''s important to accurately calculate the amount of cement, "oops", concrete for a project because it''s very expensive to buy from a redimix company.
