Abstract

Abstract The study aims to explore the causes of early cracks in prefabricated bridges and propose repair measures. The stude designs a test first. Analysis of the mix proportion and uneven shrinkage of concrete shows that, in concrete, the ratio of air content to water-binder is a quadratic parabola, the fly ash and water binder ratio have a linear relationship, and slurry collection ratio and the water-binder ratio is inversely proportional. The test results suggest that the cracks of bridges are caused by the decrease of relative humidity in concrete. Afterward, some corresponding repair measures are put forward to safeguard the prefabricated bridges.
