Strength And Durabilityassessment Of Bacteria Based Self- Healing Concrete
In recent years, there is increasing interest in the phenomenon of mechanical property recovery in concrete construction using self-healing concrete. The study was motivated by the need to find a solution for the problem of cracking approaching the concept of self-healing concrete. The study was carried out on a bacteria based self-healing concrete using Bacillus Subtilis bacteria. The present ...
متن کاملSelf-Setting Calcium Orthophosphate Formulations: Cements, Concretes, Pastes and Putties
In early 1980s, researchers discovered self-setting calcium orthophosphate cements, which are a bioactive and biodegradable grafting material in the form of a powder and a liquid. Both phases after mixing form a viscous paste that after being implanted sets and hardens within the body as either a non-stoichiometric calcium deficient hydroxyapatite (CDHA) or brushite, sometimes blended with un-r...
متن کاملSelf-Healing and Self-Care for Nurses.
The potential effects of self-care techniques to increase nurses' effectiveness and influence positive patient care outcomes have often been underestimated. Today, nurses experience increased stress as a result of more work hours and greater patient loads. Research studies demonstrate the value to an organization and to individuals of educating nurses about self-care. Studies also show that how...
متن کاملA Bacteria-Based Self-Healing Cementitious Composite for Application in Low-Temperature Marine Environments
The current paper presents a bacteria-based self-healing cementitious composite for application in low-temperature marine environments. The composite was tested for its crack-healing capacity through crack water permeability measurements, and strength development through compression testing. The composite displayed an excellent crack-healing capacity, reducing the permeability of cracks 0.4 mm ...
متن کاملThe Feasibility of Waterproof Microcapsule System for Bacteria-Based Self-Healing Cementitious Material
In this study, a waterproof material was used to fabricate microcapsule by interfacial curing reaction to encapsulate an alkaliphilic spore-forming bacterium. The technical feasibility of encapsulated spores and the influence of three kinds of curing agent on the calcium precipitation activity (CPA) of the bacterium were studied. Furthermore, micromorphology of microcapsules was observed by Sca...
