C. ethanolica is largely discovered as a waste microbe in the beer industry. The tendency of the microbe to cultivate easily and induce bio-crystals with the capability to encapsulate heavy metals; has made it mesmerizing to be explored in a sustainable manner for concrete surface coating technology. Under the influence of the optimal initial pH, calcium oxide concentration, and fungal cell concentration in the liquid growth media; the treated concrete cubes were experimented to have an average 28-day compressive strength of 32.20 MPa. Such strength value is 6.27% higher when compared to that of the untreated concrete cubes at the same curing time. Overall, the findings revealed that the fungal bio-crystals have a promising prospect to be applied as a concrete surface coating. � 2020 Final 2023-05-29T08:07:16Z 2023-05-29T08:07:16Z 2020 Article 10.1016/j.conbuildmat.2020.119482 2-s2.0-85123626459 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85123626459&doi=10.1016%2fj.conbuildmat.2020.119482&partnerID=40&md5=f92b0e646bef917c950ac22b4c398c48 https://irepository.uniten.edu.my/handle/123456789/25196 257 119482 Elsevier Ltd Scopus |
