Abstract

In this paper, an experimental investigation was carried out on mortar cubes to study the influence of Bacillus subtilis bacteria, nanosilica used as a carrier material and GGBFS (0 and 10%) as cement replacement on compressive strength by direct application and bacteria immobilization at 3, 7, and 28 days of moisture curing. The compressive strength results showed significant improvement in bacteria specimens than the control mortar specimens. Visual observations were made to witness the white powdery precipitate on the cracked areas; optical microscopic images were taken to analyze the rate of crack healing efficiency of cracked specimens and also studied the microstructural characterization of cracked compounds using scanning electron microscope (SEM).
