本文对遭受硫酸腐蚀的混凝土标准立方体试块，利用回弹仪进行了抗压强度检测，给出了遭受硫酸腐蚀的强度等级分别为Ｃ２５，Ｃ３５，Ｃ５０混凝土的专用回弹测强曲线和回归方程。
In this paper, the concrete cube test blocks subjected to sulfuric acid corrosion were tested for their compressive strength by means of a rebound tester. The specific rebound strength curves and regression equations for the concrete grades C25, C35, C50 subjected to sulfuric acid corrosion were given. .
