Wacker built a new cement and concrete technology capability center in Shanghai to help the sustainable development of silicone industry

China is the largest producer and consumer of cement and concrete in the world However, under the pressure of high energy consumption, market demand for environmental protection products and carbon dioxide emission reduction, the huge cement and concrete industry is facing many challenges, for example, the durability and corrosion resistance of cement and concrete products must be improved "Wacker's new R & D lab in Shanghai will help our customers to meet these challenges and seize market opportunities in a timely manner." Paul Lindblad, President of Wacker Greater China, said, "as a regional innovation platform focusing on cement and concrete, the new laboratory will cooperate with China's first-class universities, research institutions and related industries to develop innovative products and solutions, so as to help the sustainable development of China's building materials industry." With this new technology capability center, Wacker will further study how organosilicon chemistry can effectively protect cement and concrete from environmental impact and improve its durability For example, waterproof technology applied to cement and concrete has attracted much attention both in academia and in the industry At present, the most mature and widely used technology is silicone surface treatment technology The technology can prevent alkali aggregate reaction (ASR) on the concrete surface and prevent weathering, graffiti and corrosion However, this surface treatment technology also has limitations "One of the tasks of our laboratory is to develop new silicone products, improve the hydrophobicity and durability of cement and concrete, and solve other unsolved problems For example, organosilicon can make cement hydrophobic A product developed by the cement and concrete technology capability center of Wacker India has been successfully used to produce thousands of tons of hydrophobic cement " Dr Peter Jerschow, head of global product development team of building silicone business department, said, "as wacker's first technical capability center specializing in silicone admixture for cement and concrete, the new laboratory will make full use of our professional technical knowledge and resources around the world to provide support for China's growing cement and concrete industry." Because of its unique properties, organosilicon is widely used in building materials protection It can give the building materials excellent waterproofing, water vapor permeability, chemical resistance and ultraviolet radiation resistance, and also has many forms, such as solid powder, solvent free liquid and waterborne emulsion Its application fields include: Waterproof of inorganic insulating material, protective coating, moisture-proof, pH regulator of coating, and concrete waterproof agent.
