## How do I work out how much concrete I need?

Next, you **need** to determine square footage – do this by multiplying the length by the width. Convert the thickness from inches to feet. Then, multiply the thickness (in feet) by the square footage to determine cubic feet. Next, you **need** to convert cubic feet into yards – do this by multiplying it by 0.37.

## How do you calculate m3 of concrete?

1 **cubic meter** (1m3) can be visualised by drawing a cube 1 meter wide x 1 meter tall x 1 meter depth. To **calculate** the **concrete volume** of a **concrete** slab you multiply the length, width and depth of the **concrete** slab to get an estimate of the amount of **concrete** you need in cubic metres **m3**.

## How much extra concrete should you order?

**Ordering** Ready Mix **Concrete**

Always allow for some wasted **concrete**, which will normally vary between 5 to 10 percent of additional **concrete**. For a rectangular placing area, multiply length times width times thickness, in feet, and divide it by 27. That amount will be the necessary cubic yards of **concrete** needed.

## What is the minimum concrete order?

**Concrete** can only be ordered in ¼ yard increments, with 1 yard being the **minimum order** quantity. Quantities less than 4.25 yards are subject to an additional small delivery charge.

## How many bags of cement do I need for 1 cubic meter?

Batching by volume – DIY

Materials | 0.2 m^{3} concrete |
1 m^{3} concrete |
---|---|---|

cement (no. 25 kg bags) |
2.5 | 12 |

all-in aggregate (volume in m^{3}) |
0.25 | 1.3 |

water (volume in litres) | 32 | 160 |

cement (no. 25 kg bags) |
3.5 | 14 |

## How far does a 25kg bag of concrete go?

As a rule of thumb 1 of our **25kg bags** will cover an area of 0.25m to a recommended depth of 50mm. We also offer 855kg bulk **bags**.

## What is the weight of 1m3 of concrete?

One cubic metre of concrete weighs 2.5 **Tonnes**. Typically, 1m3 of concrete is made up of **350Kg** of cement, **700Kg** of sand, **1,200Kg** of chippings and 150 Litres of water. The mix design process can either be conducted on the basis of charts or experimentally.

## How much is a m3 of concrete?

Ready-mixed **concrete** is sold by the **volume**, so it’s essential to know the area you’re filling. The **price** of **concrete** depends on **many** factors, including where you’re located and the type you’ve ordered. However, in general, you should be looking at a **cost** of between £65 and £85 per **cubic metre**.

## How much concrete do I need for a 10×10 slab?

For a **10 x 10 slab**, we’d suggest a mix with a capacity of about 4,000 pounds per square inch, or psi. This is basic for residential projects, and it can withstand traffic and support heavy loads.

## How much does 30 yards of concrete cost?

Use $90 per cubic **yard** as a ballpark figure for **concrete prices**, but **concrete** slab **cost** will vary by region. Also, expect a fee of about $60 per load for delivery from a **concrete** truck for **concrete cost**. There could be other fees for such things as Saturday **concrete** truck delivery and small loads.

## What is the best slump for concrete slab?

A **good slump** for most flatwork placed by hand: five inches. For **slabs** struck off with mechanical equipment: two to four inches.

## What do you say when ordering concrete?

**PLACING AND CONFIRMING YOUR CONCRETE ORDER**

- Give the time you want the
**concrete**. - Give the mix number and or type you are
**ordering**. - Give the total number of yards needed.
- Let them know the spacing you want on the trucks. For example, “I need the trucks 30 minutes apart.”

## Is it cheaper to mix your own concrete?

One of the least expensive ways to get **concrete** is to **mix your own**. You can buy bags of the **mix** from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker **concrete** once it cures, which could lead to cracks or crumbles within a couple of years.

## How much does 2 yards of concrete cost?

According to the NRMCA – Ready Mixed **Concrete** Industry Data Survey, the **average cost** of **concrete** in 2018 was $120 per cubic yard, or $240 for the **2** cubic **yards** needed for a typical 10-by-10-foot patio.

Bulk **Concrete Prices**.

---|---|

1* | $140-$200 |

2* |
$280-$400 |
