Oct 24, 2017· the nominal mix is given 1:2:4(Cement:FA:CA) Loss of cement is considered as 2% Output of mix is considered as 67% To achieve 1 cum output, we need 1/0.67 = 1.49 say 1.50 cum dry mix. Now add the wastage of 2%, i.e (1.50 + 0.02) = 1.52 cum. Volume.

So care should be taken while calculating the amount of Cement, Sand and Aggregate required for 1 Cubic meter of Concrete. Method-1: DLBD method to determine material requirement for 1 Cum concrete. The DLBD (Dry Loose Bulk Densities) method is an accurate method to calculate cement, sand and aggregate for a given nominal mix concrete.

Dec 21, 2016· How To Calculate Cement Bags In 1 Cubic Meter? Let us consider the nominal mix is 1:2:4 Wastage of cement during handling is considered as 2%.

How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.

We have considered an entrained air of 2%. Thus the actual volume of concrete for 1 cubic meter of compacted concrete construction will be = 1 -0.02 = 0.98 m 3. Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as

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.

It might be 4” deep which is a normal depth for a concrete slab. So now the equation looks like this: 2’ x 2’x 4”. The problem is you have to get everything into the same units; you can’t multiple feet by inches. This is where folks get hung up but it’s actually quite easy. Just multiple 2 x 2 x 4 ÷ 12. The answer is 1.3 cubic

1 part cement, 2 part sand and 3 parts aggregate. Cement should have a grey look, if not add more cement. Mix the dry cement and sand, add water, mix, then add aggregate, and more water as needed. Water should not be freely running on top. Adjust the mix by adding more water, cement or sand as needed. Concrete must be used within 1-2 hours of

To make 1 cubic metre of concrete you will need: 9,2 bags cement + 0,60 cubic metres sand + 0,60 cubic metres stone. 1.2 small batches: use containers such as buckets, drums or tins. Use the same size of container for measuring all the materials in a batch. Use only common cement complying with SANS 50197 cement concrete sand stone 1 bag 13/

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.









Our concrete calculator allows you to accurately work out the amount of concrete you'll need for your project. Simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) You can build up a concrete calculation for complicated areas by adding additional shapes of each type.

Oct 01, 2009· How It Works: Concrete. To make 1 cubic yard of concrete, you'd need seven 94-pound bags of cement, about 1/2 cubic yard of sand and just over 3/4 cubic

If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8

One of the more common mixes is a 3/2/1 mix this combines 3 parts aggregate (crushed stone), 2 parts sand and 1 part portland cement. with this mixture to make 1 cubic meter of concrete you will

Assume water/cement ratio of 0.45 BY WEIGHT for a slab mix, so the water volume will be about 1.4 parts by volume, or 1.4 water: 1 cement: 2 sand: 3 coarse aggregates, 7.4 parts total. For 0.15 m^3, you need about 0.15/7.4 or about 0.021 m^3 of cement. That will be about 66 KG of cement, or a little more than one 50-kg sack (a common size).

for 15MPa, as per Indian code, its mix ratio is 1:2:4, and for this mix, it is shown in the above table that, cement required is 310kg of cement or 6.2 number of bags of cement, 0.434 cubic meter of sand (FA) and 0.868 cubic meter of coarse aggregate or stone.

This series of concrete calculators has been developed to help you plan your project. You can calculate how much concrete, cement, sand, mortar or render you will need. For each calculation you will have to know the dimensions of your object. The calculator will perform the sums for you where relevant it will add a small percentage for the wastage that inevitably happens when mixing & using

Post Hole Concrete Calculator. If you have a lot of posts to set, it may pay you to mix the concrete yourself. Or, if you need a cubic yard or more, order mixed and delivered. Concrete contractors can provide estimates for delivering and installing cement for your post project.

how to calculate 1:2:4 ratio concrete cement, sand, metal and water please give me brief calculation. ALLInterview. how to calculate 1:2:4 ratio concrete cement, sand, metal cement so total cement by weight we need for 100 cubic feet concrete = 17.6x50 = 880kgs sand: 2/7x154 = 44 cubic

For making concrete in a large volume, as will be needed for a pump pad, a cement trough is a very useful tool. The trough is approximately 1.2 m wide by 2 m long (4 ft. x 6 ft.) and 30 cm (12 inches) deep.

The total concrete needed for the 3' by 3' porch will be .28 cubic yards. (.11 + .17 cubic yards = .28 cubic yards) Repeat this for added layers of steps. Calculating the amount of base fill. Granite Construction has an excellent base fill calculator on their site. Use this to figure how much material you need for the subgrade.
