The invention provides a limestone powder concrete surface strengthening agent and a preparation method and application thereof. The limestone powder concrete surface strengthening agent includes A component and B component, in terms of mass percentage, A component is composed of 10%-20% infiltration expansion component, 15-25% calcium nitrate, 1-3% infiltration auxiliary component Component B consists of 10-20% osmotic hardening component, 1-2% waterproof component and the balance of water. The concrete surface strengthening agent of the invention has the effects of improving the concrete resilience of the concrete, reducing the carbonization depth and weakening the carbonization speed, and has the advantages of simple preparation and use method, low cost and wide adaptability. |
