Experimental Study on Wind Erosion of Concrete Building Surface in Wind-Sand Environment

Abstract

In this paper, the effects of different wind-sand attack angle, wind speed, action time, concrete strength, sand particle size, and sand content on the surface wind erosion of concrete structures are experimentally studied. Wind erosion rate and strength loss rate are defined as the indexes to measure the degree of wind erosion of concrete. According to the similarity theory, the actual situation is deduced based on the wind erosion test, and the wind erosion time corresponding to the wind speed, the action time of wind sand, and the simulation test in the case of sand content is obtained. it makes the experimental study of wind erosion on concrete buildings to have more practical significance.
