Process and performance additives from Evonik support the dry mortar mix industry to improve energy and resource efficiency for new and existing structures, while also reducing climate-damaging emissions. As a key component of modern construction systems, our specialty drymix mortar products offer the latest high-performance, cost optimized and sustainable construction methods.
Reinforced concrete buildings are vulnerable to penetrating moisture. Together with the pollutants dissolved in it (e.g. chlorides from de-icing salts), moisture can attack the passivation layer of the steel and lead to corrosion pitting. In the long term, the stability of the structure is affected. With PROTECTOSIL®, Evonik has developed a silane-based product family especially for construction. It has water-repellent qualities and can form a passivation layer around the steel. As a powdered product, it can be added to dry mortar mixtures during the construction process. Thoroughly mixed, it is distributed homogeneously throughout the matrix of the building material. Its long-lasting corrosion protection makes PROTECTOSIL® a product that helps to significantly reduce cost-intensive and time-consuming maintenance measures in the future.
