Founded in 1999, private high-tech enterprises in Hebei Province. The original Shijiazhuang Special Cement Plant and Shijiazhuang Special Cement Institute of Engineering and Design as the main body, 60 employees, 11 senior engineers. Built a special cement laboratory, concrete laboratory and technology information room, with science and technology development and engineering and technical conditions. With FEA concrete expanders, low slump concrete pumping agent and concrete bridges rapid repair materials three national invention patents (expander zL01140534.1, pumping agent zL01140537.6, bridge material zL01140536.8), of which two For high-tech products, a new product for the country. Product trademark for the Sihua licensing. Mainly produces four kinds of products, with expansion performance of the products include: FEA concrete expanders and multi-functional composite expansion agent, high strength non-shrink grouting material and silent broken Jing; concrete admixtures include: respectively for special cement and Portland cement Low slump concrete pumping agent, quick setting agent, retarder, early strength agent, antifreeze; waterproof products include: for sealing with water plugging the spirit, for the treatment of large areas of wet and dry Fullex infiltration crystallization Type coating, FCC flexible composite waterproof coating; high strength materials include: concrete bridge rapid repair materials, anchoring agent, express hard cement-based materials. Customer first, quality first. The use of FEA concrete expanders, bridges quickly repair commodity concrete projects, can provide technical advice, quality assurance and on-site technical services.
