High-strength concrete cement pad factory bridge pad about some special properties: 1 Durability: high-strength concrete bridge pad has good durability strength concrete bridge pad easy to damage. Pad for high-strength concrete bridges have a certain anti- frozen requirements. works for impervious to require high-strength concrete bridge pad has good impermeability and corrosion resistance. impermeability, frost resistance, corrosion resistance of high-strength concrete bridge pad durability. 2 , Intensity: high-strength concrete bridge pad after hardening of the most important mechanical properties, is resistant to high-strength concrete bridge pad pressure, pull, bend, shear stress, etc. the ability cement ratio, cement variety and amount of aggregate species and dosage and mixing, molding, curing, have a direct impact on the strength of high-strength concrete bridge pad. 3, workability: high-strength concrete bridge pad mixture has the most important performance which represents mixture has the consistency of comprehensive, mobility , plasticity, water-resistant properties of segregation and bleeding easily wipe the surface of the other four, deformation: the high-strength concrete bridge pad under load or under the effects of temperature and humidity deformation, including elastic deformation, plastic deformation, shrinkage and temperature deformation. http://www.hbhouwei.com/
