本文研究了一种自制的混凝土用表面保护剂对混凝土耐久性的影响。将其涂覆于混凝土表面,不仅可在混凝土表面形成憎水性的薄膜,还可渗入混凝土内部,与混凝土内部胶凝材料反应,提升内部混凝土的致密性。使用后混凝土的回弹值及碳化深度、抗冻等级等耐久性能都得到了显著的提升。
This article studies the effect of a self-made concrete surface protectant on the durability of concrete. Applying it to the concrete surface can not only form a hydrophobic film on the concrete surface, but also penetrate into the concrete and react with the cementitious material inside the concrete to enhance the compactness of the internal concrete. After the use of concrete rebound value and carbonation depth, antifreeze grade and other durability have been significantly improved.
