钢纤维轻骨料粉煤灰混凝土抗冲击性能试验研究
|
摘要
为了研发具有绿色性质的高性能钢纤维轻骨料粉煤灰混凝土,试验研究了钢纤维体积率、粉煤灰替代率及水灰比3种因素对钢纤维轻骨料粉煤灰混凝土抗冲击性能的影响规律。结果表明,3种因素中,钢纤维体积率和水灰比对混凝土的抗冲击性能影响较大,粉煤灰替代率对混凝土的抗冲击性能影响相对较小。试验结论可为钢纤维轻骨料粉煤灰混凝土在工程中的应用提供参考。
To develop a high-performance steel-fiber-reinforced lightweight-aggregate fly-ash concrete with green characteristics,the influence of steel fiber volume rate,fly ash substitution rate and water cement ratio on the impact resistance of concrete is studied. The results show that among the three factors, the steel fiber volume rate and water cement ratio have a great influence on the impact resistance of concrete, the fly ash substitution rate has a relatively small impact on the impact resistance of concrete. The study results can provide the basic reference for the application of the steel-fiber-reinforced lightweight-aggregate fly-ash concrete in the engineering.
