The Use of Bacillus pseudofirmus ATCC 700159 to Improve the Mechanical Properties of Concrete
Keywords:
concrete, Bacillus pseudofirmus ATCC 700159, Pre-cracksAbstract
This research aimed to study the use of Bacillus pseudofirmus ATCC 700159 in the concrete specimen. The experiment on varying bacteria ratio of 10-40 wt% into the specimens was conducted to improve the compressive strength properties of concrete and investigate new compound after bacteria being added into concrete specimens. The results obviously indicated that bacteria ratios had no negative effect on compressive strength of the concrete specimen. When creating the internal pre-crack of specimen by 40% of maximum compressive strength, it was found that the bacteria could produce a new compound and thus, increased in compressive strength. This result was confirmed by XRD, FTIR and SEM analysis which showed the most CaCO3 amount in the BC-40 specimen.
