摘要
通过试验研究了粉煤灰掺量和养护条件对活性粉末混凝土力学性能的影响。分析结果表明,混凝土的抗弯拉强度随着粉煤灰掺量的增加而略有增强,而抗压强度在粉煤灰水泥比为0.3时达到最大值,蒸汽养护对混凝土的强度有促进作用。
Through the experiments, it analysed the influence of curing conditions and the dosage of fly ash on mechanical properties of reactive powder concrete.Analysis results showed that the flexural strength of concrete was slightly increased with the increase of dosage of pulverized fuel ash, and the compressive strength reached the maximum when the ratio of pulverized fuel ash and cement was 0.3, steam curing of has a certain role in promoting the concrete strength.
