Self-healing mechanisms are new techniques used to improve structures durability. Two species of Bacteria (Bacillus subtilis and B. megaterium) were added to rich cement pastes. Cement based bacteria were tested under compression. The two mixes were compared with a control mix to study the bacterial effect on cement paste compressive strength. Ferrocement laminates were cast using the bacterial mixes and the control mix. Laminates were tested under flexural loading until failure. Tested laminates were kept moisturized. Laminates were reloaded after two months. Test results showed that bacterially based systems have the ability to heal and restore the material to its original state when damaged. Bacterially based system seems promising and sustainable.
