Abstract

Abstract

The corrosion resistance experiments of concrete with basalt fiber proportion of 0%, 0.1%, 0.2% and 0.3% were conducted, in which the conorete specimens were soaked in compound salt solutions of MgSO₄ mixed with Na₂SO₄ and NaCl, to explore the corrosion resistance of concrete specimens with different basalt fiber proportion. Based on the saline soil environment of the Southern Xinjiang area, the concrete of strength grade C35 commonly used in the existing structures in the area was adopted. The relative masses and relative of elastic moduli of specimens were selected as the main indexes for analysis and evaluation. The results showed that the fluctuation range of the relative masses and the relative elastic moduli of concrete specimens with the basalt fiber of 0.3% were lower than those of other specimens, which indicated that the resistance of concrete to erosion of compound salt solutions was improved. The analysis for microstructure of specimens showed that the main production composition in concrete immersed in compound salt solutions of MgSO₄ mixed with Na₂SO₄ and NaCl were ettringite and gypsum. The adding of basalt fibers reduced the generation of corrosion products, which was consistent with the change of its macroscopic indicators.
- saline soil,
- basalt fiber concrete,
