Abstract

The invention relates to a cement concrete deck lamina repairing agent, which comprises a component A and a component B. The component A is polymer emulsion which is either pure acrylic emulsion or styrene-acrylate emulsion. The component B is a powdered material rich in fiber, which is prepared with the following components by weight: 35 to 75 percent of an expansion agent; 0 to 20 percent of sodium sulphate; 0 to 6 percent of a water reducer; 0.5 to 6.0 percent of synthetic coarse fiber, 0 to 42 percent of pulverized fuel ash or powdered ore. After the component A and the component B are added to and mixed in concrete mixture pro rata, the repaired hardened concrete and the original concrete have high crack resistance, crush resistance, impact and grinding resistance and stripping resistance; the repaired concrete can be open to traffic after 24 hours. The cement concrete deck lamina repairing agent can be used for repairing laminae of cement concrete deck and road.

Description

【Technical field】 [0001] The invention relates to a patching material for a crack-resistant and peel-off-resistant thin layer of a cement concrete bridge deck. 【Background technique】 [0002] During the operation of the cement concrete bridge deck, the pavement laminates are prone to cracking and falling off. The damage of the bridge deck pavement is mainly caused by the following factors: [0003] 1. The rigidity of the bridge deck is insufficient, which causes large deformation under the action of heavy loads, coupled with the continuous impact and vibration of the vehicle, cracks appear on the bridge deck and pavement, and develop rapidly. [0004] 2. The bonding capacity between the pavement layer and the beam surface is insufficient. Under the load, the pavement layer and the main load-bearing member cannot work as a whole to bear the external load, which destroys the integrity of the concrete. Under the action of load, it is easy to cause peeling, cracking, peeling an...
