**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?

**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?

**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?

**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?

**25kg bags**will

**cover**an area of 0.25m to a recommended depth of 50mm.

## How much cement should I use?

**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?

**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?

**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?

**kg**weight of 1

**cubic meter**of the

**cement**.

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

## How do you work out cubic Metres?

**How to Calculate Cubic Meters**

- Measure the height of your object and record it on a piece of paper.
- Measure the length of the object and record this number, as well.
- Measure the width and write this number down.
- Multiply the three measurements. The answer is given in cubic meters.

## How many tonnes are in a cubic Metre?

**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?

**20 50kg bags**of cement.

## How many cubic meter is 25kg bag?

Cubic Metres | 20 kg Bags 25 kg Bags 30 kg Bags 40 kg Bags | 1 m³ = approx: 108 x 20 kg Bags |
---|---|---|

Bags | 20 kg Bags 25 kg Bags 30 kg Bags 40 kg Bags | 10 x 20 kg Bags = approx: 0.09 m³ |

## How many 25kg bags make a tonne?

**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 m

^{3}(

**cubic meters**).

## How much is 2 cubic meters of concrete?

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

## How many tonnes are in a cubic Metre of crushed rock?

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

**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.
