WACKER is expanding its technical support for the construction industry with the opening of an additional laboratory in Moscow. The focus here is on water-repellent silicone additives for cement and concrete, which, when added to cementitious materials, provide improved protection against moisture, salts and unwanted chemical reactions. The development laboratory, which supports customers all over the world, is now officially open for business.


The Moscow laboratory is part of WACKER’s new Innovation Hub for Cement and Concrete. The facility aims to better protect cement and concrete materials from moisture, both while in storage and after application. Up to now, moisture protection has come in the form of water-repellent silicones applied to the surface after the concrete, mortar or plaster has set. WACKER has now developed silicone additives that can be incorporated into the cement or concrete during production, thereby protecting the construction materials from moisture damage more effectively.

The Moscow lab will be taking a leading role in developing these kinds of integral treatment additives for cement and concrete.  According toThomas Koini, who leads the Performance Silicones business unit, the new lab in Moscow will give WACKER a first ever opportunity for systematically studying and testing a wide range of raw materials used in cement and concrete. This puts the company in a position to optimise its building protection agents for use in its customers’ formulations and for compliance with international construction standards.  


A large number of test devices and laboratory instruments are available for the new service. The labs operated at the site by other expert teams can be drawn upon for studies as well.  The laboratory also hopes to collaborate with local universities and testing facilities. The first projects have already been commissioned. Studies conducted at the Lomonosov M.V. Moscow State University and previous investigations at the Gvozdev A.A. Research Institute of Concrete and Reinforced Concrete, for example, have shown that hydrophobic silicones significantly reduce moisture damage to concrete caused by salt penetration or by chemical processes such as the alkali-silica reaction.
