The construction industry utilizes Portland cement which is known to be a substantial supporter of the CO2 emissions and ecological harm. Incorporation of industrial squanders like demolished old concrete, silica fumes (SF) and fly ash remains (FA) as valuable cementing materials (SCMs) could result in a significant decrease of the general CO2 …
High temperatures and external force can easily lead to a decline in the bond strength of reinforced concrete components. Microbial-induced calcium carbonate precipitation (MICP) technology has considerable potential for repairing concrete. Given this, this study utilized MICP technology to improve the bond strength of heat- and pull …
