摘要
为研究硫酸盐对早龄期玄武岩纤维混凝土的腐蚀性能的影响,对标准养护及两种不同浓度硫酸盐溶液腐蚀下的不同纤维体积掺量的混凝土试件进行了抗压强度的测定,并计算其抗压腐蚀系数K,结果表明:玄武岩纤维对早龄期混凝土的抗压强度提高不明显,且抑制了混凝土抗压强度的发展;在硫酸盐腐蚀液中早龄期混凝土的抗压强度随着玄武岩纤维掺量的增加呈下降趋势,但未随着腐蚀时间的延长而下降.
In order to study the effect of sulfate on corrosion behavior of basalt fiber reinforced concrete in early age,the compressive strength of concrete specimens with different fiber volume content under different corrosion conditions and standard curing was determined,and the compressive corrosion coefficient of K was calculated. The results show that the basalt fiber has no obvious improvement on compressive strength of the concrete,and restrain the development of the compressive strength of concrete. The compressive strength of early age concrete in sulfate solution is decreased with the increase of basalt fiber content,but does not decrease with the increase of corrosion time.
