N2 - Microbial agents are often used to enhance the performance of cementitious material. This study presents the utilization of microbes to the properties of fly ash (FA)-based alkali-activated material (AAM) paste, with ground granulated blast furnace slag (GGBFS) as partially FA substitution. Variations of GGBFS-to-FA weight ratio were between 0 and 50%. Raw material and specimens are characterized with X-ray fluorescence, X-ray diffraction, scanning electron microscope, compression test, porosity test, workability test, and setting time. Supplement of microbes to FA-based AAM enhances the strength in a limited amount up to 20% slag replacement due to its workability. AAM without GGBFS addition showed a 28-day compressive strength of 23.00 MPa. The 28-day compressive strength of 20% GGBFS substitution without and with microbes addition was 32.90 MPa and 33.50 MPa, respectively. Microbes application to 20% GGBFS substitution in AAM resulting total porosity (pf) of 19% which was lower than without microbes addition. Microbes increased the workability but fastened the setting time of fresh AAM. The X-ray diffraction (XRD) and scanning electron microscope (SEM) analysis showed the microbes image and precipitation dominated by calcite.
