Study on Analysis and Preventive Measures for Damage of Durability of Reinforced Concrete Bridges
Abstact: Based on the damage of five corrosive bridges concrete in Shanghai, it suggested that the strength and durability of C30 concrete have decreased seriously. These years, a lot of bridges, overhead roads and tram roads have been built, so the study on anticorrosion technology of reinforced concrete bridge will assuredly become a pressing issue. The main measure in this article is to design the durability of concrete aiming at the reasons why durability decreases at the different environmental conditions. The results of the research suggested that the over-replacement with active mixture technology could assuredly make Cl- penetrative resistance, freezing and thawing resistance and carbonizing resistance improve. It was best when coefficient of over-replacement was 1.3, and slag was best followed by steel slag, and then fly ash. Furthermore, the over-replacement with active mixture technology could stay concrete forepart shrinkage rate, thereby improving the durability of concrete.
