چکیده

Abstract. Elkhateeb WA, Elnahas MO, Daba GM. 2021. Review: Microbial induced mineralization of calcium carbonate for self-Healing concrete. Asian J Nat Prod Biochem 19: 1-9. Low-cost solutions achieving concrete self-healing are attracting researchers attention. Generally, mechanism has been so far accomplished by three approaches: autogenous healing, encapsulation polymeric material, and microbial carbonate. approach seems like an attractive potent, relatively cheap way to achieve self-healing. Hence, this review elucidates the mechanisms, compare roles fungal bacterial mediated

Modeling 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...

Availability of calcium from skim milk, calcium sulfate and calcium carbonate for bone mineralization in pigs.

Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 mo...

Strain-specific ureolytic microbial calcium carbonate precipitation.

During a study of ureolytic microbial calcium carbonate (CaCO(3)) precipitation by bacterial isolates collected from different environmental samples, morphological differences were observed in the large CaCO(3) crystal aggregates precipitated within bacterial colonies grown on agar. Based on these differences, 12 isolates were selected for further study. We hypothesized that the striking differ...

Bacterially induced mineralization of calcium carbonate: the role of exopolysaccharides and capsular polysaccharides.

Bacterially induced carbonate mineralization has been proposed as a new method for the restoration of limestones in historic buildings and monuments. We describe here the formation of calcite crystals by extracellular polymeric substances isolated from Bacillus firmus and Bacillus sphaericus. We isolated bacterial outer structures (glycocalix and parietal polymers), such as exopolysaccharides (...
