Quickly calculate concrete slab and footing pours by entering the depth, width and length to find the number of cubic yards or bags of concrete needed for your project. Give these calculations to your ready-mix supplier or use them to estimate how many 40, 60 or 80 lb. bags of concrete to buy.
Calculation Of Materials For Different Mix Ratio: Quantity estimation of materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete.
Following is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5, M7.5, M10, M15 and M20. if you don't want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete.
The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio.
Grades of Concrete with Proportion (Mix Ratio) We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting.
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.
The DLBD (Dry Loose Bulk Densities) method is an accurate method to calculate cement, sand and aggregate for a given nominal mix concrete. This gives accurate results as it takes into account the Dry Loose Bulk Densities of materials like Sand and Aggregate which …
Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15 etc., M stands for Mix and the following number stands for characteristic compressive strength(fck) of the concrete in 28 days in direct compression test. If the ratio for M20 concrete is 1:1.5:3 then 1 part cement, 1.5 part sand and 3 part aggregate (crushed stone) in volume is batched for mixing.
A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.
These calculations help you estimate how many bags of concrete mix you need for a concrete slab or pad. Save Item. Send to a Friend Print. Calculating the Concrete Mix You Need. The tables below give you estimates for the number of 50- or 60-lb bags you need for concrete slabs of various sizes.

CONCRETE CALCULATOR - How Much Do I Need? You can use this concrete calculator to help you determine the number of bags of QUIKRETE® Concrete Mix, Mortar Mix, or Fast-Setting Concrete you will need for the following projects.
The water cement ratio = 0.45Now we willcalculate the volume of concretethat can be produced with one bag of cement (i.e. 50 kg cement) for the mass proportions of concrete materials.Thus, theabsolute volume of concretefor 50 kg ofcement =[image]Thus, for the proportion of mix considered, with on3 bag of cement of 50 kg, 0.1345 m3 of concrete can be produced.We have considered an entrained air ...
For example, if you are trying to pour a concrete pad that is 30 feet long but changes its width every 10 feet, you might wind up with the following set of measurements in order to break down the entire pour into a series of rectangles: 10 feet long by 20 feet wide 10 feet long by …
IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm 2 .
Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure & Example Home / Concrete Technology / Concrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure & Example Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures.
