| 摘要 | The damage process and corrosion ion distribution in concrete, which was exposed to 60 and 170 drying-immersion cycles of sulfate solution, were systematically investigated. The effects of plain concrete, plain concrete mixed with 4 and 8 kg/m(3) modified PP fiber and high-performance concrete (HPC) mixed with 0.8 kg/m(3) fine PP fiber on the damage process were also studied. The experimental results showed that thenardite-induced surface scaling, as well as gypsum-and ettringite-induced cracks, were the main degradation forms of concrete under attack of sulfate solution and drying-immersion cycles. The relative dynamic modulus of elasticity of concrete initially increased, then reached stability and finally decreased to failure. The sulfate diffusion coefficients of plain and HPC were 10(-12) and 10(-13) m(2)/s, respectively. The concentration of sodium ion increased with depth, then maintained stability and finally decreased rapidly with concrete depth. The content of calcium ion on the concrete surface was 110%-150% of that in the interior of specimens. Although fiber worsened the surface scaling of concrete, better resistance capacity of sulfate ion penetration into concrete was observed in plain concrete with 4 kg/m(3) modified PP fiber and HPC. |
