The utilization of waste rubber as a viable option for manufacturing building materials holds great significance the sustainable development construction industry. This study explores addition two additives, fly ash (FA) and glass fiber (GF), to rubberized mortar in order improve its performance. impact different powder (RP) replacement rates modified additive dosages on performance mortar, including fluidity, mechanical properties, drying shrinkage, resistance, thermal insulation was investigated. Furthermore, analytic hierarchy process (AHP) adopted priorities by FA GF. results indicate that RP leads decrease shrinkage. However, it can enhance resistance properties. GF, have significant influence properties mortar. By means AHP method analysis, this concludes optimal comprehensive FA- GF-modified be achieved replacing 10% sand with using 0.4% presents configuration may lead GF being considered potential candidates developing environmentally friendly materials.

In marine structural engineering, the impact resistance of concrete holds high significance. The determination whether combined use expansion agent (EA) and glass fiber (GF) has a synergistic effect on seawater–sea-sand (SSC) plays role in its performance application. this study, dynamic Brazilian disc test at various strain rates was carried out with an SHPB device to investigate mixing 0% 6% EA 1% GF splitting tensile properties SSC. results show that rate GF-reinforced SSC during tests higher rates, indicating strong sensitivity. reinforcement consumed more energy under loading, thus maintaining morphological integrity concrete. However, strength obtained had significant overload which cannot be ignored. doped showed enhancement SSC’s properties.
