Concrete mix ratio simply means the amount by volume of cement, fine aggregate (which can be sharp sand) and coarse aggregate (which can be granite, gravel, etc). For example, a concrete mix ratio of 1:2:4 simple means 1 head-pan of cement you need to mix 2 head-pans of sand and 4 head-pans of granite.

M-20 = 1 : 1.5 : 3 = 5.5, (Cement : Sand : Aggregate) Some of Mix is – 5.5. Where, M = Mix. 20 = Characteristic Compressive strength. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation to find Cement, Sand and Aggregate quality in 1 cubic meter concrete.

Solution: In case of M10 concrete, the ratio of cement, sand and aggregate is 1 : 3 : 6. Dry volume of concrete = wet volume of concrete × 1.54. Hence, the dry volume of concrete is = 3 × 1.54 = 4.62 m 3. The required quantity of cement is = (Cement ratio ÷ Sum of all ratio) × Total volume of concrete = = 0.462m 3.

To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-.

We find out the volume of concrete in wet condition 1m3 (After the consolidation of Cement + sand + water). So in dry conditions, we have to add 30 to 35% sand bulkage and add 20% for wastage. Accounting bulkage of sand - 34%

Both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete.

Paving mix - 1:3½ cement:all-in ...

Answer (1 of 13): If you are using a design mix, you don't even need to calculate. It would be mentioned in the design report. See the image below. However, if you are using a nominal mix (I would advise against it if it's an important/critical structure), then you …

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. 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 ...

G = volume of gravel per cubic meter of concrete work (m 3 of gravel / m 3) c,s,g = cement-sand-gravel ratio (relative amounts of solids by volume in a mixture) C = 55 / (c+s+g)

Match and calculate sand, gravel, and cement quantities using the concrete proportion table: Volume * Cement Multiplier for a Class "A" in 40 kg bags = 0.90m3 * 9 = 8.1 bags. The volume of sand is equal to the quantity of sand. For a Class "A" mix, the sand multiplier is 0.90m3 *.5 = 0.45m3. Gravel Quantity equals Gravel Volume.

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 ) * …
