The purposes of this study are: 1) to synthesize the composite silane-based water repellent by hibridization of perfluoroalkylsilane (PFAS) and organic alkoxysilane; 2) to evaluate durability of concrete coated by the water repellent. As a result of morphology observation after applying the water repellent to concrete, the spherical silane composite compounds penetrated deeply into the concrete caplillary pores to form a three-dimensional network structure. The composite silane-based penetrating water repellent improve the durability performance such as non-absorptive performance, permeability resistance, chloride ion penetration resistance, acid resistance, and scaling resistance at freezing. Also, the results of penetration depth, non-absorptive performance, and permeability resistance satisfy the quality standard of KS F 4930 and EXCS(2019).
