Abstract

The invention provides an impact-resistant and anti-wear agent for hydraulic concrete, which mainly comprises a nano material, slag, latex powder, rubber powder, a water reducing agent, fibers, an exciting agent and a defoaming agent. The impact-resistant anti-wear agent is suitable for places such as water conservancy projects, roads and airport pavements requiring high impact-resistant and anti-wear concrete, has the functions of resisting crack, reducing water, reinforcing and reducing elasticity, and excellent mixing and constructing properties. The impact-resistant and anti-wear agent has the advantages of increasing concrete impact-resistant and anti-wear properties, prolonging maintenance period and reducing maintenance cost.

Description

technical field [0001] The invention relates to the technical field of anti-shock and wear-resisting agents for hydraulic concrete, which are mainly used in hydropower construction projects, and can also be used in projects such as roads and airport runways. Background technique [0002] The water flow contains a large amount of suspended matter and moving matter, which has a strong destructive ability driven by the high-speed water flow, and continuously collides and rubs against the concrete on the flow surface of the hydraulic structure, causing the concrete to appear scouring wear, Damage phenomena such as cavitation threaten the safety of hydropower stations, and they need to be regularly maintained and repaired, which not only affects power generation efficiency, but also requires huge maintenance and repair costs. [0003] At present, the solutions to improve the impact and wear resistance of concrete include silica fume series impact and wear resistance concrete, mod...
