Concrete Calculator

Concrete can be purchased in multiple forms, including in 60 or 80-pound bags, or delivered in large amounts by specialized concrete mixer trucks. Proper mixing is essential for the production of strong, uniform concrete. It involves mixing water, aggregate, cement, and any desired additives. Production of concrete is time-sensitive, and the ...

How Much Ballast Do I Need To Mix Concrete? | TJC Transport

The right amounts of ballast or sand-aggregate can also be expressed in simple ratios. So for the concrete mix mentioned above, your cement: sand: aggregate ratio should be 1:2:4 or ballast to cement ratio of 6 to 1. For a low-grade concrete with 10MPa strength, the perfect ratio should be 1:3:6. For 30MPa concrete use 1:0.75:1.5.

How much ballast do I need for a cubic Metre of concrete ...

In this regard, "how much ballast do I need for 1m3 concrete?", generally, you need 58 bags of 25kg (total 1458kg) ballast or 1.7 jumbo or bulk bag of 1 loose tonne ballast for 1m3 of concrete by using standard mix of 1:5 (1 cement:5 ballast).

How many bags of cement required for 1m3 of Cement?

So, Usually, 4% of moisture content is present in cement. Dry Density of Cement = 1440kg/m 3. Each bag of cement consists of = 50kg. No. of bags in 1m 3 = 1440/50. = 29bags (approx)

Concrete Mix Ratio Using Ballast - How Much Ballast Do You ...

Concrete Mix Ratio Using Ballast. For typical domestic use, 1 cubic metre of concrete at 3500 psi (25 MPa) can be readily created by mixing seven 50 kg bags of cement with 0.7 cubic metres of sand and 0.7 cubic metres of stone aggregate. Concrete of this strength is ideal for patio slabs, footpaths and steps. By increasing the cement:aggregate ...

How many 25kg bags of ballast in a cubic metre - Civil Sir

How much ballast and cement do I need Cement quantity = 1/6 × 1m3 = 0.166m3, we know weight of cement = volume × density, so weight of cement in kg = 0.166m3 × 1500kg/m3 = 249kg, if weight of cement bag is 25kg, then number of bags of 25kg cement as 249/25 = 10 bags, therefore you need 10 bags of 25kg cement for 1m3 concrete by using ...

Concrete Calculator - Estimate Cement, Sand, Gravel ...

Concrete mix estimation. Our mix-on-site concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and ...

Metric calculator for concrete - cement, sand, gravel etc

Both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete. Calculator are provided for a general mix and a paving mix, the different ratio of materials are: General mix - 1:5 cement:all-in ballast or 1:2½:3½ cement:sharp sand:gravel. Paving mix - 1:3½ cement:all-in ...

Concrete Calculators - cement, sand, gravel and all-in ...

How many bags of cement per ton of ballast - Civil Sir

We have mix ratio for ballast is 1:6 by volume, it means 6 parts of 1 ton ballast yields 0.6m3 volume, so 1 part of cement volume is 0.6/6 = 0.1m3, therefore required volume of cement is about 0.1m3, which yield about 150kg of cement equal as 6 bags of 25kg cement. 1 ton ballast how much cement?

How many tonnes of ballast to 1 cubic meter of concrete ...

hi. you will require 2.5 tons of ballast to concrete your area of 5metres x 3 meters at 100mm thick so that will be 3 one ton bags. regards darren. T08:50:02+01:00. Answered 16th May 2011.

How much ballast and cement do I need for 1.6m cubed of ...

28096. For 1m3 of footing you need 2 tonne of aggregate and 10 - 12 bags cement, so for 1.6m3 you need 3.2 tonnes and about 18 bags of cement. Personally I would consider getting a concrete company to deliver 1.6m3. By the time you have all the materials and paid for the labour, it will be cheaper! T09:50:04+00:00. Answered 5th Dec 2013.

5 inches = 0.42 feet. 8 inches = 0.67 feet. 11 inches = 0.92 feet. 3 inches = 0.25 feet. 6 inches = 0.5 feet. 9 inches = 0.75 feet. This same principle applies when dealing in metric. If you enter your first two measurements, (for example, 5 metres x 3 metres) and your depth is 6 inches or 150mm, you would enter this as 5m x 4m x 0.150 = 2.3 ...
