混凝土抗风蚀磨损表面强化处理材料的对比试验研究
Comparative Experimental Research on Concrete Surface Treatment Materials Resistance to Wind Erosion
摘要
Abstract
The second double-track section in Xinjiang of Lanzhou-Xinjiang Railway crosses the five most powerful wind areas of the nine wind areas in Xinjiang. For wind erosion to the railway concrete structure, by means of abrasion resistance and hydrophobicity tests, four kinds of concrete surface treatment materials were chosen to carried through research to improve the abrasion resistance of concrete surface. The results show that four kinds of surface treatment materials can all improve the abrasion resistance of concrete surface to wind erosion. Among which, permeable composite latex concrete surface treatment material has comprehensive advantages in abrasion resistance, hydrophobicity and price. It can penetrate through the surface of concrete by surface seepage method and react with concrete to form a dense hydrophobic net structure on the surface to achieve the effects of protection and resistance to wind erosion. It can improve the abrasion resistance of concrete surface more than doubled, and the surface drying time is reduced 99. 35%. It has better effect in anti-ultraviolet, anti-cracking and anti-freezing, etc.关键词
