• ### Concrete Calculator Estimate Cement, Sand, Gravel

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.

• ### How To Calculate Cement, Sand & Aggregates Quantity in

03.08.2018· We Know in one bag of cement = 1.226 CFT For Calculate in CFT (Cubic Feet) = 8 x 1.225 = 9.8 Cubic Feet CALCULATION FOR SAND QUANTITY; Consider volume of concrete = 1m 3 . Dry Volume of Concrete = 1 x 1.54 = 1.54 m 3 Sand= (1.5/5.5) x 1.54 = 0.42 m 3 ∴ 1.5 is a part of Sand, 5.5 is sum of ratio . Density of Sand is 1450/m 3

• ### Calculate Sand & Gravel per 50kg Cement Bag in Volume

Lets calculate weight of sand and gravel needed for M15 Grade concrete. Weight of Sand required per bag of cement = (330/3) x 1 = 110 kg. Weight of gravel required per bag of cement = (330/3) x 2 = 220 kg. Therefore to prepare M15 Grade concrete, use

• ### How To Calculate Cement, Sand And Coarse Aggregate For

Water Cement Ratio Calculation From the IS Code standard, Assuming the water-cement ratio for M20 is 0.55. Therefore required water quantity = Cement Volume X WC Ratio = 0.282 X 0.55 = 0.1551 m3 Unit weight of water = 1000 Litres / m3

• ### How to Calculate Cement Sand and Aggregate Quantity in

Quantity of Cement = Dry volume/sum of ratio × ratio of cement = 1.54 / 7 × 1 = 0.22 cum (where 1 is ratio of cement) Quantity of cement in kg = 1.54 / 7 × 1440 (Density of cement = 1440 kg/ m3) Quantity of cement in Bags = 316.8 / 50 = 6.336 (weight of one bag cement = 50 kg)

• ### Estimation of Cement, Sand, and Gravel in Construction

G = volume of gravel per cubic meter of concrete work ( m3 of gravel / m3 ) c,s,g = cement-sand-gravel ratio (relative amounts of solids by volume in a mixture) C = 55 / (c+s+g) S = 0.028*C*s. G = 0.028*C*g. The classes of concrete mixture depends on the cement-sand-gravel ratio (c:s:g).

• ### How to Calculate Cement, Sand and Coarse Aggregate

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

• ### How to Calculate Quantities of Cement, Sand and

The dry volume of concrete mixture is always greater than the wet volume. The ratio of dry volume to the wet volume of concrete is 1.54. 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

• ### Concrete Mix Ratios (Cement, Sand, Gravel)

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard. A general rule of thumb is, if the water is palatable then it is suitable for

• ### How to Calculate Quantities of Cement, Sand and

Incase you want to convert the requirement of Sand and Aggregate in Cum; 1 Cum = 35.31 Cft Eyeopener:Many popular blogs claim M20 nominal mix as 1:1.5:3 ,however we strongly differ by same.Through this blog,we are also trying to address the same myth which is being carried forward since last 4 decades.. The reason being: With constant research and development in the field of cement

• ### Calculation of the amount of cement, sand and gravel

Proportions and consumption of cement, sand and gravel for making concrete cube of a default given the resource, as recommended by manufacturers of cement. Likewise, the price of cement, sand, gravel can vary significantly in different regions. The composition of the finished concrete mixture depends on the size (fractions) crushed stone or gravel, cement brand, its

• ### Concrete Calculators cement, sand, gravel and all-in

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.

• ### Calculate Quantities of Materials for Concrete -Cement

Quantities of materials for concrete such as cement, sand and aggregates for production of required quantity of concrete of given mix proportions such as 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25) can be calculated by absolute volume method. This method is based on the principle that the volume of fully compacted concrete is equal to the absolute volume of all the materials of concrete
