In today's world, the role of concrete industry has become an important element in ecoNomic, structural and architectural issues. But it should be Noted that cement production, as the main component of concrete structures, has a significant share (about 7%) in Co 2 emissions from the atmosphere, which is in contrast to sustainable development. Hence, for many years, the community of researchers has sought to find an aPropriate alternative to reduce or eliminate Portland cement from the concrete industry, which can be considered as a turning point in current research. With all the kNowledge about concrete durability, concrete demolition is a major dilemma that threatens the service life of concrete structures, especially hydraulic structures. Dams and other hydraulic structures are structures with long service life, due to the high repair cost, the durability of these structures is important, it is clear that concrete design based only on the compress strength canNot secure durability and service life in different environments. Therefore, considering the durability parameters is required in addition to the resistance in order to design a concrete. Concrete industry in order to develop sustainable, concrete design based on durability should be considered in order to ensure the service life of the structure and reduce waste of materials. For the destruction of concrete, the destructive factors must first be able to penetrate the concrete body in the first step. Therefore, it can be state that the permeability of concrete is one of the most important factors in the life of concrete structures. Emphasizing that in most models, the prediction of the service life of concrete structures based on the amount of carbonation depth and chlorine penetration depth is referred to as the main factor in the coefficient of permeability of concrete. The purpose of this study was to investigate the permeability of alkali active slag concrete one part and investagation of the effective parameters on it. Alkali active slag concrete one part is produced by activating the slag of the Isfahan smelter using sodium metasilicate along with common aggregates in the market. in the first step, the effect of sodium metasilicate on slag and the effect of the type of treatment on the permeability of this type have been experimented. Then, by adding different amounts of microsilica, naNo silica and polypropylene fibers, to study the slump tests, compressive strength, water impermeability , Chlorine ion permeability and carbon dioxide gas permeability have been investigated. Also, in order to clarify some structural changes in alkali active slag concrete one part, X-ray diffraction (XRD) has been used. In general, among the results obtained in this study, better performance was observed in plastic treatments in comparison with water treatment samples. Also, the positive effect of microsilicon and naNosilica on compression strength and permeability parameters is one of the observations of this study.
