Abstract: ABSTRACT Method for Producing a Synergistic Algae-Bacteria-Based Self-Healing and Carbon-Sequestering Cementitious Composite The present invention relates to a bio-mediated method for preparing a self-healing and carbon-sequestering cementitious composite, herein referred to as ALBAcrete. The method comprises cultivating a viable photosynthetic microorganism, concentrating the biomass by separating it from a substantial portion of its culture medium, resuspending the concentrated biomass in fresh water to obtain a concentrated live microalgal suspension, preparing a viable biomineralizing bacterial culture, and co-incorporating both biological components as liquid suspensions into the cementitious composite during mixing. In a preferred embodiment, the photosynthetic microorganism is Arthrospira platensis, and the biomineralizing bacterium is Bacillus alkalophilus. The synergistic interaction between the concentrated live microalgal suspension and the bacterial culture promotes biologically induced calcium carbonate precipitation, resulting in autonomous crack healing, enhanced carbon dioxide sequestration, microstructural densification, improved mechanical strength, and better durability of the cementitious composites.
