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 ... -
Evaluating the surface functional groups on banana leaf petioles and the resultant biochar for potential adsorbance
Ndung’u, Paul W.; Mwithiga, Gikuru; Onyari, Charles N.; Muriithi, Genson; Mukono, Simon T. (JMES, 2020)The presence of surface functional groups is key to the performance of an adsorbent material. The aim of this study was to evaluate the presence of functional groups on banana leaf petiole and on biochar made from ... -
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 ... -
