Abstract Co-cultured bacterial spores from alkaliphilic and alkali-tolerant strains exhibit superior performance compared with those from single strains because of their higher resistance to pH and harsh environments, which promotes biofilm formation and CaCO3 precipitation. In this study, spray-dried co-cultured bacteria spores have been incorporated into cement mortar to explore their effects on its self-healing, mechanical properties, and durability. They showed high survival, decreased mortar sorptivity, and well-crystalline CaCO3 formation; on the other hand, the 28-day compressive strength of the mortar was severely reduced, and the water porosity raised.
