OUR CONCRETE
Concrete is a composite material composed of fine and coarse aggregate bonded together cement that hardens (cures) over time. Concrete is said to be the second substance most used in the world after water, and is one of the most frequently used building materials.

OUR KEY FIGURES
In Réunion, the group produces and distributes cement, concrete, and structural elements for floors (joists, pre-slabs, beams) in pre-stressed concrete for the construction sector and other sectors related to construction. Just as CEMENTIS strengthens the bond between the five communities of the Indian Ocean, cement is an adhesive solution used in concrete. It is the main ingredient of concrete, composed of sand, aggregates, additives and water. Cement itself is a fine mineral powder obtained at the end of a very precise manufacturing process. Mixed with water, this powder forms a paste that sets and hardens, even underwater.
What is cement?
Cement is a crucial binding agent in construction. It sets, hardens, and forms a strong bond with other materials, making it essential for holding them together.
What are the main types of cement?
The primary types of cement include Portland cement, white cement, hydraulic cement, rapid-hardening cement, and sulphate-resistant cement. Each type has specific properties suited for different applications.
What is the difference between cement and concrete?
Cement is a key ingredient in concrete. Concrete is a composite material made from cement, aggregates (like sand and gravel), and water. While cement binds the ingredients together, concrete provides the structure and strength used in various construction projects.
How is cement used in construction?
Cement serves multiple purposes in construction. It is essential for making concrete, mortar, stucco, and grout, each with its specific use in building and repair.
What is the proper water-cement ratio?
The water-cement ratio is crucial for achieving the right consistency and strength. For most applications, the ideal ratio ranges from 0.4 to 0.6 by weight.
Can cement be used alone without aggregates?
Cement alone is not used for construction purposes; it needs to be mixed with aggregates and water to create concrete or mortar. This mixture provides the necessary strength and durability for building projects.
