ABSTRACTWith the rapid expansion of industrial and civil construction, demands for concrete its production has increased significantly, resulting in massive wastage. An effective strategy to recycle solid waste involves aggregation producing concrete. In this study, through two layers mortar concrete, changing rule influence mechanism waste-glass particles on mechanical properties permeability recycled aggregate pervious (RAPC) were analysed. The results indicated efficacy using instead natural river sand promoting hydration enhancing calcium silicate hydrate (C–S–H) content, thereby improving compactness pore structure Specifically, strength RAPC with an increase particle whereas exhibited a reverse trend. When replacement rate is 100%, compressive peaks at 24.19 MPa, which approximately 66.48% greater than that manufactured sand, coefficient 0.63 mm s−1, meets requirements set Faced limited availability mineral resources, substitution fine aggregates conducive sustainable development.KEYWORDS: Waste-glass particlerecycled (RAPC)strength performancepermeabilitymicrostructure AcknowledgmentsThis work was supported by North China University Water Resources Electric Power. authors also would like acknowledge support National Natural Science Foundation (52109154,51979169); Technology Research Project Henan Province (222102320439); Fund Innovative Education Program Graduate Students Power, (NCWUYC-2023020).Disclosure statementNo potential conflict interest reported author(s).
