چکیده
Silica fume can be used in place of cement to make reinforced concrete more resistant to corrosion. Cracks and corrosion can also be treated using Bacillus subtilis bacteria added to the mix. Using non-destructive testing, this study intends to ascertain the effects of silica fume addition to concrete bacteria on the mechanical and corrosion characteristics of the material. The beams and cylinders used in the tests were 50 x 10 x 10 cm3 and 30 x 15 cm3, respectively. In place of cement, the specimens had 8%, 10%, and 12% silica fume, and 10 ml (105 cfu/ml) of Bacillus subtilis bacteria were added. The direct current power supply is used in the accelerated corrosion process for 48, 96, and 168 hours. Regarding compressive strength, the typical concrete specimen tested at 37.59 MPa was the strongest. Silica fume concrete outperforms regular concrete in the flexural strength test. Compared to regular concrete, superior results were obtained from non-destructive tests conducted on silica fume concrete utilizing impact echo and resistivity instruments. The longer the concrete is exposed to corrosion, the lower the impact echo and resistivity values that are subsequently measured. By accelerating the corrosion process of silica fume concrete by 48, 96, and 168 hours, respectively, the impact echo and resistivity values for corrosion resistance reached their maximums of 12%, 10%, and 8%.

تازه های تحقیق
  • Replacing 8%, 10%, and 12% of cement with silica fume improves the corrosion resistance of concrete.
  • Adding Bacillus subtilisbacteria helps heal cracks and reduces corrosion in the concrete mix.
  • Impact echo and resistivity tests were used as Non-Destructive Testing (NDT) methods to evaluate strength and corrosion resistance.
  • Silica fume concrete showed higher flexural strength, while regular concrete had the highest compressive strength of 37.59 MPa.
  • Silica fume concrete showed better corrosion resistance, with the best results at 12% silica fume after 48 hours of accelerated corrosion testing.
  • Corrosion exposure lowered impact echo and resistivity values, but silica fume concrete consistently outperformed regular concrete.
