摘要
基于泵送工艺生产PHC管桩对混凝土的技术要求,研究并探讨了矿物掺合料的种类、混凝土水胶比、含气量以及外加剂对混凝土的和易性和蒸养强度的影响,提出了满足PHC管桩泵送生产的混凝土关键原材料的选择及技术指标控制范围。
Based on the technical requests of PHC pile produced by pump concrete method,mineral admixture type, water binder ration, air content, and chemical admixture are studied and discussed. The method of choosing key materials and several main specifications are put forward to satisfy the producing process.
