Method and process for reinforcing RC (Reinforced Concrete) beam of E-glass fiber fabric reinforced magnesium phosphate cement-based concrete thin-slab

The invention discloses a method and a process for reinforcing an RC (Reinforced Concrete) beam of an E-glass fiber fabric reinforced magnesium phosphate cement-based concrete thin-slab; the method is characterized in that a thin plate made from many layers of E-glass fiber fabric nets is paid in magnesium phosphate cement-based fine concrete and stuck on the bottom of the present reinforced concrete beam to reinforce the beam; and the reinforced magnesium phosphate cement-based fine concrete thin-slab is poured layer by layer with a U-shaped mold, manufactured in a top-pressing manner and stuck with E-glass fiber fabrics. The magnesium phosphate cement has the features of being good in bonding performance with fiber fabrics and no corrosion to the E-glass fiber fabrics; the magnesium phosphate cement-based fine concrete cooperates with the low-price E-glass fiber fabrics, so that the reinforced concrete is reinforced and strengthened; therefore, the engineering cost is reduced greatly under the condition that the load-bearing capacity of the structural part is improved effectively.
