Bioremediation of mortar made from Ordinary Portland Cement degraded by Thiobacillus thioparus using Bacillus flexus
Ngari, Reginah Wangui; Thiong'o, Joseph K.; Wachira, Jackson M.; Muriithi, Genson; Mutitu, Daniel K. (Heliyon, 2021-06)Cement is widely used as a construction material in the construction industry. However, there are challenges affecting its durability efficacy. Cement mortar/concrete is subject to degradation by aggressive ions such ... -
Influence of Lysinibacillus sphaericus on compressive strength and water sorptivity in microbial cement mortar
Mutitu, Daniel Karanja; Wachira, Jackson M.; Mwirichia, Romano K.; Thiong'o, Joseph Karanja; Munyao, Onesmus Mulwa; Muriithi, Genson (Elsevier, 2019-11)Cement structures are subject to degradation either by aggressive media or development of micro/macro cracks which create external substance ingress pathways. Microbiocementation can be employed as a self-intelligent solution ... -
