BEHAVIOURS OF NATURAL AND SPOROSARCINA PASTEURII (BACILLUS PASTEURII) AS A LINER
Downloads
The enhancement of sandy soil as a liner and cover material for usage as waste containment facility was taken into consideration in this work using Bacillus pasteurii to activate the microbial-induced calcite precipitation (MICP) process. This study aimed at determining the physical properties of SPOROSARCINA PASTEURII (BACILLUS PASTEURII) as a liner. The study's sandy soil, which had a natural moisture content of 8.56%, came from Wudil Local Government Area in Kano State, Nigeria. Stepped Bacillus pasteurii suspension densities of 0 cells/ml, 1.5 x 108 cells/ml, 6 x 108 cells/ml, 12 x 108 cells/ml, 18 x 108 cells/ml, and 24 x 108 cells/ml were applied to the sandy soil. The Atterberg's limit test result, which showed that the soils were nonplastic, was used to determine the index properties of the soil. The soil was classified as A-3(0) and SP soil, respectively, according to the AASHTO and USCS classification systems. The specific gravity decreases with increase in Bacillus pasteurii suspension density
