Concrete Calculator - Estimate Cement, Sand, …
Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and 1600 kg/m 3 (bulk density of stone) respectively, when calculating in metric units.

Consider volume of concrete = 1m3 Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 Sand= (1.5/5.5) x 1.54 = 0.42 m3 ∴ 1.5 is a part of Sand, 5.5 is sum of ratio Density of Sand is 1450/m3
Concrete Calculators - cement, sand, gravel and …
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:all-in ballast or 1:2½:3½ cement:sharp sand:gravel. and ; Paving mix - 1:3½ cement:all-in ballast or 1:1½:2½ cement:sharp sand:gravel.
How to Calculate Quantities of Cement, Sand and …
So 1.54 Cum of dry materials (cement, sand and aggregate) is required to produce 1 Cum of concrete. Volume of Cement required = 1/(1+2+4) X 1.54 = 1/7 X 1.54 = 0.22 Cum. Volume of Sand required = 2/7 X 1.54 = 0.44 Cum or 15.53 cft. Volume of Aggregate required = 4/7 X 1.54 = 0.88 Cum or 31.05 cft. Note: 1 cubic meter = 35.29 cubic feet
How to Calculate Cement, Sand and Aggregate …
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
Metric calculator for concrete - cement, sand, …
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 mix and a paving mix, the different ratio of materials are: General mix - 1:5 cement:all-in ballast or 1:2½:3½ cement:sharp sand:gravel. and ; Paving mix - 1:3½ cement:all-in ballast or 1:1½:2½ cement:sharp sand:gravel ...
Calculate Quantities of Materials for Concrete …
The volume of concrete required for concrete structure can be calculated by summing up the volumes of each structural member or each parts of members. The volume of a rectangular cross sectional member can be calculated as length x width x height (or depth or thickness).
Importance of Gravel and Sand for Concrete | …
Concrete is made up of cement and water plus an aggregate composed of sand and gravel. The sand and gravel do more than act as filler, though. The size and amount of gravel added to a bag of concrete also determines the products volume, strength, and durability.

Determining Moisture in Aggregate ... - Concrete …
Sand can be expected to contribute about 2 to 6 percent free moisture by weight, and gravel or stone about 1 or 2 percent. Under average conditions that means that 104 pounds of sand would give you the equivalent of 100 pounds of sand in what is called a saturated surface dry (SSD) condition and 4 pounds (1/2 gallon) of free moisture.
