摘要
本研究旨在评估硅烷基渗透密封剂(PS)、两种水泥基涂层(CC1 和CC2)以及聚合物涂层(PC)在混凝土表面的透水性和防水性能,并探讨水蒸气透过率与防水性能之间的关系.实验采用 100mm混凝土立方体作为测试对象,通过对比各密封剂和涂层产品在相同条件下的性能,测试它们对混凝土防水性能和水蒸气传输能力的影响.实验结果表明,水泥基涂层CC2 在降低水蒸气透过率方面表现最佳,同时展现出最高的防水性能.相比之下,水泥基涂层CC1 的水蒸气透过率最高,防水性能最低.渗透密封剂PS的透水性较高,防水性能较差.聚合物涂层PC在透水性和防水性能方面均表现优异.此外,研究还发现,涂层体系的水蒸气透射率与其防水性能之间存在显著的相关性,这一发现为预测和评价涂层的性能提供了重要参考.
Abstract
This study aims to evaluate the permeability and waterproof performance of silane-based penetrating sealant(PS),two cement-based coatings(CC1 and CC2),and a polymer coating(PC)on the surface of concrete,and to explore the relationship between water vapor transmission rate and waterproof performance.The experiment used 100 mm concrete cubes as test subjects,comparing the performance of various sealants and coatings under identical conditions to assess their impact on the waterproof performance and water vapor transmission capability of concrete.The results showed that the cement-based coating CC2 performed the best in reducing water vapor transmission rate,while also exhibiting the highest waterproof performance.In contrast,the cement-based coating CC1 had the highest water vapor transmission rate and the lowest waterproof performance.The penetrating sealant PS showed higher permeability and poorer waterproof performance.The polymer coating PC demonstrated excellent performance in both permeability and waterproof capability.Furthermore,the study found a significant correlation between the water vapor transmission rate and the waterproof performance of the coating systems,providing important insights for predicting and evaluating the performance of coatings.
