成果介绍

本发明公开了一种预测混凝土硫酸盐侵蚀深度的方法，方法包括：根据混凝土结构的扩散系数、混凝土表面硫酸盐浓度、混凝土内部初始硫酸盐浓度、化学反应计量数、铝酸钙在所述混凝土结构中的含量，并结合时间参数及扩散系数衰变指数建立硫酸盐侵蚀深度多参数数学模型；根据第一时刻及第二时刻及其对应的侵蚀深度获取待预测时刻侵蚀深度数学模型，并根据所述待预测时刻侵蚀深度数学模型获取待预测时刻的侵蚀深度。通过本发明建立的硫酸盐侵蚀深度预测模型，在实际工程应用上无需获取环境中硫酸盐溶液的浓度、温度和侵蚀方式以及水泥中铝酸三钙含量等参数的具体值即可预测侵蚀深度，使得预测混凝土的硫酸盐侵蚀深度模型更具有工程实用性。
