Self-healing of early age cracks in cement-based materials by mineralization of carbonic anhydrase microorganism
This research investigated the self-healing potential of early age cracks in cement-based materials incorporating the bacteria which can produce carbonic anhydrase. Cement-based materials specimens were pre-cracked at the age of 7, 14, 28, 60 days to study the repair ability influenced by cracking time, the width of cracks were between 0.1 and 1.0 mm to study the healing rate influenced by widt...
متن کاملThe Role of Autogenous Bone Marrow in the Healing of Experimental Burn Wound Healing in Rabbits
Objective- To evaluate the role of autogenous bone marrow (BM), in the healing of experimentally induced burn wound in rats. Design- Experimental in-vivo study. Animals- 20 adult male white New Zealand rabbits. Procedures- Two burn wounds were created under general anesthesia using a 100 W electric soldering iron, heated to the point of redness (about 800° C) on each side of the back, 4...
متن کاملSelf-healing of Early Cracks in Cement-based Materials by Carbonic Anhydrase Microbiologically Precipitation Calcium Carbonate
ID No: 65 ABSTRACT This research studies the self-healing potential of early cracks in cement-based materials incorporating carbonic anhydrase (CA) bacteria. CA bacteria can accelerate the CO2 hydrated reaction then transfer CO2 to HCO3 which can react with soluble Ca(OH)2 on the surface of specimens. Calcium carbonate deposits because of the reaction of HCO3 with Ca.This research studies the s...
متن کاملModeling of Self-Healing Concrete: A Review
Self-healing concrete (SHC) has received a tremendous attention due to its advanced ability of automatic crack detection and crack repairing compared to the standard concrete. Two main approaches which considered as to-date self-healing mechanisms are autogenous and autonomous healing. In the past several years, the effort of the research has been focused on experimental works instead of numeri...
