Saint-Gobain Recherche and industrial mortars

Saint-Gobain Recherche's multidisciplinary teams, in partnership with SG Weber, are involved in developing innovative solutions for ready-mixed mortars.


SG Weber markets industrial mortar solutions which are essential materials in the construction field. Regularly used and simple in appearance, they are in actual fact complex, technical products.
Using raw materials such as sand, cements and additives, a very wide range of industrial mortars are produced for various applications: tile adhesives, exterior wall coatings, screeds (levelling of floors), decorative floors, exterior insulation solutions, concrete repairs...

Quality and durability are ensured not only through control of the basic raw materials but also by the formulation of these materials with additives that confer on them unique properties.

In order to optimise their characteristics, the Saint-Gobain Recherche teams work on:

• controlling the chemistry and reactivity of the cement binder: the rheological and mechanical properties and durability conferred by the cement binder in the presence of water are dependent on highly complex hydration reactions. Controlling these reactions involves in-depth micro-structural (in particular SEM), chemical and mineralogical analyses.
• the flow behaviour (rheology) of the mortar paste
• the mechanical behaviour of the hardened material
• providing new functions such as waterproofing or resistance to colonisation by algae or fungi to increase the durability of the mortars and making them free of dust and lighter to improve their application.
