This study examines the use of rice husk ash (RHA) and incinerated sugarcane press mud (ISPM) as precursors in lime/pozzolan geopolymer system effect bacterium Lysinibacillus sp. WH on mechanical properties microstructures. The RHA-to-ISPM ratio was varied, pastes were cured at ambient temperature. results show that an increase ISPM content up to 5% improves strength reduces water absorption voids, while higher levels beyond degrade quality paste. An setting times due amount calcium pastes. Notably, addition bacteria resulting a reduction has been proved for first time this work. Moreover, can enhance all introduce self-healing abilities, with microcracks healing within < 20 days treatment, regardless mix proportions. Microstructural studies, using scanning electron microscope (SEM), Fourier Transform Infrared Microscopy (FT-IR), X-ray diffraction (XRD), Rietveld refinement analysis, reveal cristobalite, decrease quartz, thus enhancement Furthermore, work is provide evidence tend reduce efflorescence formation confirmed by gaylussite. These findings pave ways production more sustainable systems via upcycling wastes prolonging service life bacterial activity.
