  • What Is the Ratio of Portland Cement to Rock & Sand?

    21/09/2017· Concrete is a mix of coarse rock, fine sand and a water-activated substance that binds the rock and sand together. In the modern era, that binder is Portland cement. Ingredient Ratio. A good general purpose concrete mix combines one part Portland cement, 2.5 parts sand, three parts gravel and 0.5 parts clean water. For more strength and water resistance, reduce the sand to two parts. Mix dry

  • Concrete Calculator Estimate Cement, Sand, Gravel

    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.

  • How much cement sand & aggregate required for M20

    weight of sand & aggregate required for 50 kg cement bag for M20 grade of concrete. As we find 8 bags of cement,680 kgs sand & 1302 kgs aggregate for 1 cubic metre of m20 grade of concrete. Hance 8 bags cement = 680 kgs sand. For 1 bag of cement = 680/8= 85 kgs sand. Hance 8 bags of cement = 1302 kgs aggregate.

  • How much cement, sand & aggregate required for

    Ans. :- 0.385 m3 ( cubic meter) cement required for 1 cubic metre of M25 concrete. How much cement required for M25 concrete in Kgs. step 5:- calculate cement required for 1 cubic metre of M25 concrete in Kgs ( kilogram) is equal to = 1/4 × 1.54 m3 × 1440 Kg/m3 = 554 Kgs.

  • How much cement sand & aggregate required for M7.5

    How much cement sand & aggregate required for M7.5 concrete volume of sand & aggregate required for 50 kg cement bag for M7.5 grade of concrete. As we find 3.42 bags of cement,22 cft sand & 41.5 cft aggregate for 1 cubic metre of m7.5 grade of concrete. Hance 3.42 bags cement = 22 cft sand For 1 bag of cement = 22/3.42= 6.43 cft sand

  • How To Calculate Cement, Sand & Aggregates Quantity in

    03/08/2018· 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. For KG = 0.42 x 1450 = 609 kg As we know that 1m 3 = 35.31 CFT

  • Concrete Mix Ratios Cement, Sand, Aggregate and Water

    Cement 611 pounds; Sand 1450 pounds; Stone 1600 pounds; Water 33 to 35 gallons; So, you can see more cement and less sand is needed to get stronger concrete mix, which is ideal for driveways, pool decks, exterior patios, sidewalks and commercial garages. Irrespective of the batch size, it is imperative to keep the ingredients in the same ratio.
