Concrete

We produce concrete in batching plants located close to construction sites, i.e. between 20 and 30 km away. Given its setting time, concrete must be delivered to the place where it is used within no more than two hours. We also operate mobile batching plants on our customers’ sites, in accordance with their needs.

Our ready-mixed concrete batching plants are equipped with:
· a storage area: silos containing cement, sand, and gravel, and storage tanks holding the various admixtures (such as plasticizers),
· a mixer for combining the required quantities of the different concrete ingredients
· mixer trucks—with rotating drums—into which the concrete is discharged for delivery to construction sites

The characteristics and performance of a given concrete are dependent upon exacting criteria:
· a very precise mix design, especially with respect to water content
· a rigorously respected production cycle that complies with precise standards, especially with respect to continuous and uniform mixing.

Our concrete batching plants are automated to meet all these requirements and to ensure the reliability of the process. 

We propose a comprehensive offering of ready-mixed concretes that will satisfy the specific requirements of every project: decorative concretes, self-leveling concretes, self-consolidating concretes, road concretes, architectural concretes, civil-engineering concretes. The manufacture of all these concretes takes account of environmental, quality, and safety considerations.

Due to our expertise and strict quality control, we are able to supply concretes with special technical characteristics to meet the requirements of every jobsite. The properties involved include:

· setting time

· pumpability

· placement

· climate conditions

· shrinkage 

· structural strength.

These different technical properties are obtained by:

· varying the proportions of cement and aggregate

· adding admixtures: set retarders or accelerators

· replacing some of the cement by products derived from other industries, such as fly ash or blast-furnace slag.

The concretes we produce are the result of work performed developed by our research and development laboratory. They correspond to 4 categories:

· regular concrete: determined by a type of cement and a 28-day compressive strength to achieve a strength range of 20 to 40 MPa

· high-performance concrete (HPC): custom-manufactured to special mix designs, particularly as regards cement content, for a strength range of 60 to 100 MPa

· fiber-reinforced concrete: designed for enhanced crack resistance, enabling construction of more slender structures. BCV (Béton Composite Vicat) concrete is an example

· special concretes: tailored solutions developed and fine-tuned in our laboratory to meet highly specific customer requirements 

Our laboratory enables us to offer concretes that are increasingly easy to place. We also offer new horizons for applications.

Our subsidiary SATM Grands Travaux operates stationary batching plants installed on major construction sites to produce ready-made concrete for use in infrastructure projects such as high-speed railroads, freeway bridges, nuclear power plants, canal locks, airports, dams, etc. in France and internationally. In addition to manufacturing concrete, SATM is a recognized partner for major projects, providing services such as supply of materials, transport, and pumping.
