Cement

Listen

Cement is a complex material with many uses. For example, as a hydraulic binder it can act as a very sophisticated glue. Lafarge researchers are working to develop cements suited to diverse customer needs while reducing the impact of these products on the environment.

Sensium® technological cements

In 2006, Lafarge launched Sensium®, 100 % dust-free technological cement. Based on Group's Japanese research, Sensium® was developed at an international level before being adapted to the needs of local markets through knowledge transfers among Lafarge entities.

 

This innovation was perfected by Lafarge research and marketing teams. They performed a highly detailed survey of users to determine their expectations and establish a precise specifications sheet. The survey then guided the work of the R&D teams.

 

Result: Sensium® offers great ease of use. It hardens more quickly and increases the strength of the mortars and concretes in which it is used.

 

Customers report on the ease of use and technological qualities of Sensium®.

Cement

Formidable strength

After hardening, cement maintains its strength and stability, even underwater. Cement is usually used in a powder form. It is mixed with water and aggregates (sand and gravel) to make concrete.

Chape Liquide®, an efficient, economical mortar

Chape Liquide®

Mortar

Mortar is a mixture of cement, sand (an inert component which provides body) and water, which may be complemented with additives, supplements and colored pigments. Unlike concrete, mortar does not include aggregates. It may be prepared on site or delivered from a mixing plant. Mortars are used for bonding (to join cut or molded elements), for cladding (waterproofing and dressing of walls and coverings, finishing of floors), and for a number of other purposes including jointing, rendering, insulating, sealing and plugging.

Glossary

Chape Liquide® is a ready-mixed, self-leveling, self-spreading mortar which makes it easy to pour perfectly flat floors. It offers many advantages:

  • rapid pour and hardening,
  • acoustic and thermal insulation,
  • lightweight screeds,
  • resistance to weights of up to 150 kg/m²,
  • strength without steel reinforcement.

 

Chape Liquide® is an environmentally-friendly product. Its manufacture requires very little energy. The mortar is produced using local sand so there is no need to transport sand over long distances. It is produced in concrete plants which apply policies to conserve natural resources.
