Cement bag: how to choose it according to the use

You want to do some work and you need cement. This material is indeed very useful for a whole lot of achievements. But did you know that there are different types of cement to meet different types of uses?

Cement consists of 80% limestone and 20% clay heated to a temperature of around 1,500 ° C. The mixture obtained is then reduced to a fine powder. Then just use pure cement, concrete or mortar according to your needs. Before you get started, let’s take a look at the four shades of this multi-use product to help you choose the best formula for your project.

Gray cement, for masonry and structural work

Gray cement is the best known and most widely used form of cement. It is mainly used to make concrete with water and gravel, or even mortar.

Gray cement is used for masonry and structural work. It is in fact used to make a cement screed, for laying concrete blocks, stones or bricks as mortar, or even for your facade plaster. There are several variations depending on your needs, some being able to withstand more cold or humidity.

This cement is relatively easy to work, but it is not recommended to use it at a temperature below 5 ° C.

White cement, an aesthetic mortar

White cement has the same properties as the different variants of gray cement in terms of strength, strength and durability. Its white base is obtained thanks to a clever sorting work which aims to extract the ferrous components, which are gray in color, and to inject kaolin, a pure white clay which gives it its color. However, it is possible to tint this white cement to give it another color.

This type of white cement is used above all for its aesthetics. More expensive than traditional gray cement, it is used as a mortar for laying stone walls and tiling, but also for making door sills and patio doors or even exterior window sills.

Fast-setting cement, for specific jobs

As the name suggests, quick-setting cement is a separate product, the components of which allow it to harden very quickly. It is manufactured by a simple process which consists in firing a clayey limestone at a lower temperature than for other cements, of the order of 1000 to 1200 ° C.

This fast-setting cement is used for constructions which require almost immediate hardening, such as for the construction of fences, to fill holes, to renovate a facade, or to operate in an environment too humid to support traditional cement.

Refractory cement, for high heat production

This other type of cement is made from aluminum oxide. Like refractory concrete, refractory cement is able to withstand very high temperatures, that is to say above 1000 ° C thanks to this component.

It is a cement at a higher cost, mainly used for projects subject to high heat. This is the case for fireplaces and inserts, wood-fired ovens, pizza ovens, hard barbecues, etc.
