在混凝土和钢筋混凝土排水管制品中掺用粉煤灰

Bleding pfa into concrete and reinforced concrete pipe drain

本研究对悬辊法生产的混凝土和钢筋混凝土排水管制品的混凝土中掺用粉煤灰进行了试验和分析。结果表明:混凝土和钢筋混凝土排水管中掺用粉煤灰或复合其它外加剂,不仅可以降低水泥掺量、改善混凝土的和易性,而且对提高混凝土的耐久性,特别是提高混凝土的抗渗性效果显著。

The main research is on test and analysis about concrete and rainforced concrete drain pipes with fly ash produced by Rocla process,The results show that fly ash or other additives when they are used in concrete or vainforced concrete drain pipes not only can reduce cement content andimprove workability,but also have effect on dura- bility and impermeability of concrete.
