However, its relatively low strength and poor durability have limited its broader application in engineering. This study systematically investigates the effects of different mix proportions and types of retarders on the mechanical properties, microstructure, and durability of PGSM, aiming to optimize the mix design for improved strength and durability.The results show that under the optimal formulation, the mortar achieves flexural and compressive strengths of 7.5 MPa and 13.7 MPa at 24 h, respectively, and reaches 11.6 MPa and 33.3 MPa after 28 days of drying—exceeding the G25-grade requirements specified in JC/T 1023–2021: Gypsum-Based Self-Leveling Mortar. Increased PG content promotes the formation of C–S–H gel and Ettringite (AFt), thereby significantly enhancing the strength. In contrast, quartz sand and calcium carbonate serve only as fillers; excessive amounts reduce strength. The addition of cement does not improve performance linearly. Excessive cement may produce early C–S–H gel that envelops hemihydrate gypsum particles, hindering their hydration and leading to reduced workability and strength. Durability tests indicate that while the G25-grade mortar shows some strength degradation under outdoor exposure, it still meets the frost resistance requirements of the Chinese standard for <em>Test Methods of Basic Properties of Building Mortar</em> (JGJ/T 70–2009). Furthermore, SimaPro-based life cycle assessment suggests a relatively low environmental burden of PSLM. However, further evaluation of potential health impacts during the resource utilization process is needed. This research provides a theoretical foundation for the performance optimization and practical engineering application of PGSM.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"47 ","pages":"Article 102185"},"PeriodicalIF":5.8,"publicationDate":"2025-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144919781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its mix design is complex due to multiple interrelated factors such as binder content, binder proportion, alkaline activator to binder ratio (AAS/B), sodium silicate to sodium hydroxide ratio (SS/SH), and NaOH molarity, often requiring numerous trial mixes. This complexity makes the process time-consuming and a barrier to its widespread adoption. This study presents a systematic approach to optimise high-strength (M60 grade) GPC using slag and dolomite as binders under ambient curing conditions. The Taguchi method was used to evaluate five mix parameters at four levels each, reducing the number of experimental trials from 1024 (factorial design) to just 16. The results showed that binder proportion, AAS/B ratio, and NaOH molarity significantly affect both compressive strength and workability. AAS/B ratio was most influential on workability, while binder proportion critically influenced strength. The optimised mix—430 kg/m<sup>3</sup> binder, 80:20 GGBS:dolomite, AAS/B = 0.45, SS/SH = 2, and 10 M NaOH—achieved a 28-day compressive strength of 71.10 N/mm<sup>2</sup>. A regression model is developed using standardised data to predict compressive strength for high strength slag-dolomite based geopolymer concrete, which yielded a high predictive accuracy (R<sup>2</sup> = 0.94, RMSE = 2.01 N/mm<sup>2</sup>, MAE = 1.577 N/mm<sup>2</sup>). The novelty of this work lies in combining GGBS and dolomite in ambient-cured GPC, guided by a robust statistical framework.
