- W3093503058 abstract "Under the suitable condition, Bacteria, can precipitate calcium carbonate that can improve the strength and durability of cement mortar. The growth of the bacteria is facilitated by Nutrients Broth Growth Medium (NBGM) that contain the required bacteria growth nutrients. In this paper, the concentration of Bacillus Coagulans bacteria and the amount of NBGM on the strength and durability of cement mortar was assessed. The mix ratio of the cement mortar id three-part sand and one part ordinary Portland cement, with 0.5 water to cement ratio. The assessments were made at the age of 3, 7, 14 and 28 days after mixing of the bio-cement mortar and casting of the bio-cement mortar cubes. The NBGM used contained 3g of nutrient broth, 20g of urea, 10g of NH 4 Cl and 2.12g of NaHCO 3 , all per litre of distilled water. The adopted bacterial cells concentration are 1.5x10 8 cells/ml, 6.0x10 8 cells/ml and 1.2x10 9 cells/ml. For each bacterial concentration, NUB of 0%, 30%, 40% and 50% replacement of the mixing water was used. The results show that the 28 days compressive strength of the control specimen as well as for the three respective bacterial concentration is 24.08 N/mm 2 , 24.53 N/mm 2 , 24.14 N/mm 2 and 24.21N/mm 2 . It was established that the strength increase with an increased amount of nutrients broth growth media, with the highest compressive strength of 28.02 N/mm2 for the mortar with lowest bacteria concentration of 1.5x10 8 cells/ml. The water absorption was also found to be decreasing with an increasing amount of the NUB. This is a confirmation of increased durability. The improvement in strength and durability was also evident in the SEM results." @default.
