Abstract

This paper explores the influence of RS( I ) corrosion inhibitor on the performance of sprayed concrete, and makes a comparative study on the solid effect of a tunnel in Guangdong Province. The results show that when adding 20kg/m³, RS ( I ) not only does not affect the setting time of sprayed concrete, but also reduces the chloride ion diffusion coefficient of concrete, and can improve the strength and corrosion resistance of sprayed concrete. In engineering application, the anti -corrosion sprayed concrete mixed with 20 kg/m³ RS ( I ) shows good mechanical and durable properties, which shows that compared with ordinary sprayed concrete, the 28d strength is increased by 44.5%,28d chloride ion diffusion coefficient is reduced by 13.7%,and the effective diffusion coefficient is "low".
