RISMicrobial Concrete: Way to Enhance the Durability of Building Structures
Publisher: American Society of Civil Engineers
Abstract: Natural processes, such as weathering, faults, land subsidence, earthquakes, and human activities, create fractures and fissures in concrete structures that can reduce the service life of the structures. A novel strategy ...
Nondestructive Monitoring of Bacterial Intrinsic Self-Healing in Cementitious Structures Using Ultrasonic Wave Propagation
Publisher: ASCE
Abstract: Microbial induced calcium carbonate precipitation (MICCP) has applications in improving the quality of cementitious constructions by enhancing its compressive strength, reducing porosity, and increasing durability against ...
Development of Biocementitious Grout Using a Silica Fume–Based Bacterial Agent for Remediation of Cracks in Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: The self-healing of cracks via biomineralization in bacteria-based concrete has shown remarkable results in recent decades. This novel technique uses the ability of bacteria to precipitate CaCO3 for sealing cracks, and is ...
Crack Bioremediation in Concrete by Photoautotrophic Cyanobacteria through Fly Ash–Based Cementitious Biogrout
Publisher: ASCE
Abstract: Microbially induced calcium carbonate precipitation (MICCP) is widely employed in various engineering applications, including repairing cracks in cementitious materials. Many of these studies were performed using heterotrophic ...
Utilization of Biomineralized Steel Slag in Cement Mortar to Improve Its Properties
Publisher: ASCE
Abstract: Steel slag, an industrial waste generated in the production of steel, has cementitious properties due to high contents of free CaO. In the present investigation, different bacteria were isolated from steel slag and tested ...
