Lithium slag (LS), an industrial waste byproduct generated during lithium salt production, is characterized by its harmful trace elements, significant stockpiles and low pozzolanic activity. By 2003, the annual discharge of in China surpassed 15 million tons, creating urgent need for established large-scale disposal technologies. One primary strategies effective utilization LS application as auxiliary cementitious material concrete. However, reactivity challenges associated with impede utilization. Enhancing activity pivotal substantial incorporation into This study begins analyzing physicochemical properties volcanic ash derived from various extraction techniques. It subsequently explores diverse activation techniques aimed at improving within Ultimately, this paper highlights significance synergistic strategies, particularly co-excitation multi-exciter composite excitation. These approaches are identified critical pathways enhancing LS. Through exploration, aims to unveil innovative that bolster resource efficiency LS, thereby facilitating concrete domain.

Current space exploration focuses on returning to the Moon expand capacity by improving technology. The long-term presence of humans and robots requires development durable habitats for missions. In recent decades, in situ resource utilization (ISRU) construction materials has been recognized as a viable option. However, addition nanomaterials, which exhibit high strength-to-weight ratio, not incorporated with ISRU framework This paper investigates impact carbon nanotubes (CNTs) lunar simulant-based geopolymers’ compressive strength water retention. evaluation retention indicates another potential recapturing capability. this study, CNTs can enhance mechanical properties geopolymer. Two simulants were used, representing Highland Mare regions Moon. Experimental variables included CNT concentration, four curing regimes (ambient curing, two oven-curing methods, microwave radiation), dispersion time aqueous solutions. Results showed that positively influence both gain during regimes, but extent appears be dependent simulant type regime. consistently outperformed from perspective, regardless presence. benefits more pronounced at ambient temperatures. Even under poor conditions—where availability may limited temperatures 80 °C—CNTs aid retaining within geopolymer matrix, leading improved compared counterparts. Under same conditions, higher concentration further confirmed their role geopolymerization, greater observed samples containing CNTs. Additionally, radiation was explored an alternative conventional oven drying, showing reducing duration. Finally, findings suggest combining could recovery reuse, contributing high-strength infrastructure reduced energy cost requirements.
