Construct a concrete slab

Building professionals know this well, the construction of a concrete slab involves certain knowledge . Among other things, knowledge of the calculation to be done to convert a perimeter into cubic meters. This calculation allows you to find out what quantity or volume of concrete to prepare.

First of all, we will explain how to make concrete with the view of pouring a concrete slab yourself . Whether it is to make a terrace in front of your house, to prepare a support, a basin or to arrange a garage, knowing how to prepare your concrete is essential.

Make your own concrete

DIY (Do It Yourself) and DIY enthusiasts like to do their own concrete and constructions. Building a part of your home yourself is a real satisfaction. But for this it is important to refer to a reliable calculation .

You don’t have any concrete experience? Don’t panic, we explain everything to you. Concrete is made from several building materials . To make your concrete yourself, here’s what you need:

  • Sand;
  • Water
  • ; Cement;
  • Gravel;
  • Possible adjuvants;

If you want to make your concrete yourself, you must be able to strictly respect the volume of each material required. It is quite common on construction sites that many measurements are made in square meters . Now, for the calculation of the volume of concrete necessary for pouring a concrete slab, this is a volume you will need.

For your work, how to convert the perimeter of your concrete slab, expressed in square meters, in volume, expressed in cubic meters?

Concrete: the conversion of square meters to cubic meters

To make its concrete absolutely perfectly, the right amount of sand is needed, but also gravel, water and cement. You have your measurements in square meters, that is, the perimeter of your slab and the formwork you are going to perform? We remind you that before any volume calculation, you must have the exact calculation in square meters :

Perimeter (Surface) concrete slab = length x width in meters

Volume concrete slab = (length x width) x thickness chosen for your slab (centimeters to be converted to meters)

The amount of concrete to be manufactured will directly depend on the nature of the concrete slab to be poured. If you pour a concrete slab indoors , the thickness of your concrete slab should be at least 12 centimeters. You will usually have to disburse 20 centimeters.

For an outdoor concrete slab , it is advisable to opt for a larger thickness. Disbursement can be up to 40 centimetres for a terrace, with a slab thickness of at least 15 centimetres.

Do not forget to convert centimeters thickness in meters . 15 centimeters are 0.15 m. For a terrace of 6 meters by 4 meters with 15 centimeters thick, so you will need:

6 x 4 = 24 m²

24 m² x 0.15 m = 3.6 cubic meters of concrete to be prepared.

It is advisable to always prepare a surplus of concrete rather than realizing that the volume is not enough. You have your calculation to make your own concrete slab alone.

Dosing for making concrete

In terms of the dosage and volume of each material (volume of sand, volume of gravel, volume of water and volume of cement), the following are the traditional distributions for foundations :

  • 5 x 1 volume of sand;
  • 7 x 1 volume of gravel;
  • 2 x 1 volume of cement;
  • 1 volume of water.

If you do not respect this volume and its distribution, you may have either too liquid concrete or too dry concrete, which jeopardises its properties and structure. Volumes can be done directly in the bucket , for convenience.

For all your work, you will only have to buy bags of cement, sand and gravel to make your concrete. Do not lose sight of the fact that the dosage of each volume of cement, sand, gravel and water will not be the same for concrete for foundations, posts, post anchors or lintels.

Properties of concrete

Today, concrete has properties that are widely recognized in the middle of building and construction. Concrete, with its sand and gravel base, is highly resistant, strong, resistant to pressure and various aggressions . It is used for the construction of the most imposing buildings as a simple slab for garden terrace.

Prior to being used above ground, the use of concrete was reserved for foundations in major work. Since then, many formulas have been developed to strengthen the properties of concrete.

Concrete is now known for its great adaptability on many construction sites. By armouring concrete, in particular, its structural properties are magnified. The resulting structure is time-resistant, reliable and durable. A concrete slab is highly resistant to heat , fire, water, vibration and weed or root intrusions.

Many surfaces today are made of concrete, including in the city, for decorative or for fruitful ustrine.
