Ready-mixed concrete (BPE) is concrete that may be used right on the job site, as the name implies. This indicates that it is made in a stationary concrete batching plant and so has extremely defined properties.
Concrete is made up of varying quantities of cement, water, and particles, depending on the type of concrete wanted. In addition to these three components, adjuvants can be added, which will be integrated during the mixing process and will reinforce certain features of the concrete.
The inclusion of admixtures will make it possible to alter several aspects of concrete, including mechanical strength, impact resistance, handling, and so on. As a result, depending on the climate of the structure and the sort of use that will be made of it, it is critical to carefully select the possible admixtures to be employed.
Did you know?
Rain is a significant effect in road construction. Waterlogging can occur if asphalt concrete is excessively permeable. In the winter, water might freeze in some areas, causing an increase in volume and, as a result, a little swelling of the roadway. After the water has melted, air bubbles form, which, depending on traffic density, might cause the highway to age prematurely. It is so conceivable, for example, to restrict concrete cracking and thereby water infiltration by adding an admixture.
Why use BPE?
We must begin with the technical component, because manufacturing concrete in a factory eliminates all of the issues that can arise during on-site manufacture (non-homogeneous concrete, arduous handling). Not to be neglected is the precision in dosing and mixing that may be achieved at the facility rather than on the job. With the knowledge that all quality tests have been met, the concrete obtained can meet all of the needed parameters. But that’s not all; industrial production rates also allow for increased efficiency while lowering the costs of material logistics management (immobilization, reception, storage).

A wide range of ready-mixed concrete options
Concrete that has slowed down
It’s a concrete that’s employed when there’s a considerable distance between the job site and the concrete plant, for example. Setting retarders are then utilised to slow down the concrete’s hardening so that it can always be managed on site. For the same reasons, it’s also used in the summer when there’s a lot of heat.
Concrete that self-consolidates
They are extremely fluid, which gives them a definite advantage as soon as formwork is made. Naturally homogeneous, they therefore do not need to be vibrated. They are often used for the manufacture of vertical elements (wall and posts) for a better coating of reinforcements or for slabs.

We are used to gray concrete, but in recent years, colored concrete has appeared. This coloring can be obtained in several ways, in particular by using coloring pigments, by choosing colored aggregates, or by using a colored resin at the surface. It can for example be used to delimit the different roadways and therefore improve visibility (pedestrian, cyclist or bus lane).
The tensile strength of concrete is relatively low. With this type of concrete, a system of synthetic or metallic fibers is used to improve this resistance and therefore limit cracking.
It is used to designate cement concretes. To name a few: resistance to rutting, resistance to hydrocarbons and ease of processing are advantages of this type of concrete. They can, for example, be used in service stations, but also in tunnels because of their light color, which in the long term allows savings in terms of lighting.
