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.

Also asked, how much ballast and cement do I need?

Mixing 1 part cement to 6 parts ballast creates concrete suitable for driveways, paths and patios, and increasing the ratio to 1:8 gives foundation-strength concrete. It is of course possible to add other materials to increase the strength of the concrete – these often include steel reinforcing bars (“rebar”).

Subsequently, question is, how much is a cubic meter of ballast?

Weights of materials.
Dry sand fine=1.28 tonnes per cubic metre
Topsoil (some moisture)=1.44 tonnes per cubic metre
Ballast=1.76 tonnes per cubic metre
gravel (MOT Type 1 scalpings)=1.92 tonnes per cubic metre

In this way, how many bags of cement do I need for 1 cubic meter?

Each bag of cement weighs 50 kg and so 6 to 7 bags is required for M25 Grade concrete. One cubic meter of concrete includes water as well.

How do you mix 1 cubic meter of concrete?

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.

## How many bags of cement does it take to make a tonne ballast?

You'll need a bit more than one 1 ton bags of ballast and around 6 bags of cement I reckon. A 1 ton bag is actually around 900Kg ish, so probably 40-45 bags at 25kg each is my guess. 1:4 ratio is quite strong, 1:6 would be fine – 12 shovels of ballast to 1/2 bag of cement.

## What is the strongest concrete mix ratio?

In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.

## Can I use ballast as a sub base?

Ballast, gravel and hardcore

MOT Type 1 (hardcore) is crushed carboniferous limestone, used to create a hardcore base under patios, paving, driveways and artificial grass. It can also be used as a filling product.

## What is the mix ratio for concrete?

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.

## How much does a 25kg bag of cement cover?

As a rule of thumb 1 of our 25kg bags will cover an area of 0.25m to a recommended depth of 50mm.

## How much cement should I use?

For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards.

## How much is a bag of cement?

A bag of cement, portland cement, 94 pound in the USA, less in Canada, used with sand, rock and water to make concrete runs right at \$10 around here. Prices vary of course.

## How much is concrete per m2?

\$60 to \$85 per square metre for plain concrete. \$65 to \$90 per square metre for a reinforced concrete pathway. \$75 to \$90 per square metre for coloured concrete. \$100 to \$150 per square metre for an exposed aggregate finish.

## How many kg is a cubic meter of cement?

1440 kg weight of 1 cubic meter of the cement .

1,529.20 kg

## How do you work out cubic Metres?

How to Calculate Cubic Meters
1. Measure the height of your object and record it on a piece of paper.
2. Measure the length of the object and record this number, as well.
3. Measure the width and write this number down.
4. Multiply the three measurements. The answer is given in cubic meters.

## How many tonnes are in a cubic Metre?

The cubic meters amount 0.42 m^3 converts into 1 t, one tonne(Metric). It is the EQUAL concrete mass value of 1 tonne (Metric) but in the cubic meters volume unit alternative.

## How many tons is a 50kg bag?

Cement is often purchased in tonnes and when converted, one tonne of cement is equal to 1000 killogrammes of the product. So basically, a tonne of cement will produce about 20 50kg bags of cement.

## How many cubic meter is 25kg bag?

## How many 25kg bags make a tonne?

Using 25kg sacks: 40 × 25kg sacks, each costing £0.30, for a total of £12.00. Using 1,000kg bulk bag: 1 × 1,000kg bulk bag, each costing £7.50.

## How many m3 are in a tonne of gravel?

How much is a tonne of gravel? A tonne of moderately damp gravel typically fills about 0.595 m3 (cubic meters).

## How much is 2 cubic meters of concrete?

2 cubic metres of concrete is about 4.5 to 5 ton.

1.6 tons

## How many cubic meters are in a bulk bag?

Also called “dumpy bags” or “bulk bags”, the most common size can hold about 0.7 cubic metres of logs which, being less dense than sand or gravel, will weigh considerably less than a ton.
