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。
通過試驗研究瞭粉煤灰摻量和養護條件對活性粉末混凝土力學性能的影響。分析結果錶明，混凝土的抗彎拉彊度隨著粉煤灰摻量的增加而略有增彊，而抗壓彊度在粉煤灰水泥比為0.3時達到最大值，蒸汽養護對混凝土的彊度有促進作用。

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.
