Analysis of non-axenic biomasses for self-healing concrete

As an alternative to the usage of axenic bacteria achieve microbially induced calcium carbonate precipitation (MICP), this study evaluates two non-axenic biomasses as self-healing agents. A fungi-based consortium (Yeast) and heterotrophic nitrifiers (HTN) were harvested from incubation agricultural side streams. The characteristics identified through flow cytometry, total suspended solids volatile tests. incorporation into concrete was evaluated in terms compressive strength, healing ability. Self-healing ability analyzed microscope imaging on prismatic (60x60x220 mm) samples. Cracks with a three-point bending test where widths controlled LVDT sensor. curing period 56 days applied samples visual inspection conducted at start end optical microscope.
