Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubic') compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8.

Density of cement = 1440 kg/m3. Cement in 1 bag = 50 kg. 1m3 = 35.3147 cubic feet. Mix ratio is = 1:3 ( one part is cement and 3 part is sand) Total proportion = 1+3= 4. Part of cement = 1/4. Part of sand = 3/4. calculation :- we know that while we calculate dry volume of cement mortar cofactor 1.33 is multiply in wet volume of mortar ...

Quantity of Aggregate in cum = 1.54 / 7 × 4 (where 4 is the ratio of aggregate ) = 0.88 cum. Quantity of Aggregate in kg = 0.88 × 1500 (Density of Aggregate = 1450 to 1550 kg / cum ) = 1320 kg. Quantity of Aggregate in cubic feet = 1.54 / 7 × 4 × 35.314 = 31.07 cft . Alternative way. Quantity of Aggregate in cubic feet = Nos of cement bags × Volume of one bag cement in cft × Ratio of ...

Answer (1 of 3): RCC design has few nominal mixes and rest are design mixes.. Whatever be the case the proportions will be known. Eg:M15 - 1:2:4 For calculating the quantities you first take the sum of the proportion or dry mix…that's 1+2+4=7 Now proportion of cement =1/7 Sand=2/7 Aggregates...

That is, for 1m 3 of wet cement mortar, 1.6m 3 of materials are required. 2. Now we calculate the volume of materials used in cement mortar based on its proportions. Let's say, the proportion of cement and sand in mortar is 1:X, where X is the volume of sand required. Then, the volume of sand required for 1:X proportion of 1m 3 cement mortar ...

First, we calculate the volume of the slab, and then this volume is converted into a wet condition to dry condition and then find out how much material is required for the slab. Total volume of slab = L x W x H. = 20 x 20 x 0.583 = 233.2 cft. Convert wet volume to dry volume. Dry volume = wet volume x 1.54 (Wastage of sand Bulking all included)

So, Sand required = 0.072*1600 = 115 kgs. and Aggregate required = 0.144*1450 = 209 kgs. Considering water/cement (W/C) ratio of 0.55. We can also arrive at the Water required = 50*0.55 = 27.5 kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 27.5 kgs of water to produce M20 grade concrete.

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

Answer (1 of 5): Calculating Quantities of Materials for per cubic meter or cubic feet or cubic yards concrete Consider concrete with mix proportion of 1:1.5:3 where, 1 is part of cement, 1.5 is part of fine aggregates and 3 is part of coarse aggregates of maximum size of 20mm. The water cement ...

🕑 Reading time: 1 minuteQuantities 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 […]

The specific gravity of cement = 3.15 Grade of cement = 33, 43, 53 Where 33, 43, 53 compressive strength of cement in N/mm2. 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

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.

In this construction video tutorial, we will learn how to calculate the quantity of cement, sand and aggregate in RCC slab. Assume a slab having length = 5 m and breadth = 3 m and thickness = 10 cm. Compacted volume of slab = 3 x 5 x 10/100 = 3 x 5 x 0.1 = 1.5 m 3. Change the volume into loose volume which is = 1.54 x 1.5 = 2.31 m 3.

Reinforced cement concrete or RCC calculator can be used to calculate M15, M20 and M25 mix ratio of cement, sand and jelly. At materialtree.com, you can also shop for superior quality cement bags at best market price.
