Shijiazhuang cement pad

The role of the cement pad Shijiazhuang brief: 1, fire protection insulation layer of concrete having a certain effect, when a fire easily softened reinforcement of protection, the protection through the thin thickness, easy to crack under a high temperature environment, the Reinforced lower intensity due to overheating and thus damage to the overall structure. 2, the protective layer on the steel to withstand external forces have anchoring force, the use of concrete and steel anchoring force, the two closely together to participate in the work. Protective layer is too thin or missing, the anchoring force reduces its resistance thus reducing the structural effect of axial force and bending moment. 3. Maintain structural durability. Concrete protective layer is too thin, easy to penetrate wet gas and water, too thick is easy to produce cracks that may make steel corrosion and expansion, leaving the concrete damaged, affecting the use and structural safety. Thickness Bridge Materials Co., Ltd. specializes in production of reinforced protective layer pads, cement pad and other pads products based specialized companies. http://www.hbhouwei.com/
