摘 要:采用聚羧酸高效减水剂技术,对双免工艺(免蒸养、免蒸压)PHC管桩混凝土的配合比、工艺制度以及经济成本作了研究。结果表明,采用双免工艺生产PHC管桩在技术指标、生产工艺、经济成本等方面均是可行的。同时提出了适合珠三角地区的PHC管桩双免工艺生产方案,符合低碳、环保、经济的发展要求。
Abstract: Using high efficiency polycarboxylate superplasticizer, mix proportion, process system and economic cost of PHC pile concrete produced by non-steamed and non-autoclaved technology are studied.The results show that the technical indicators, the production process and economic cost and so on are feasible to produce PHC pile using the non-steamed and non-autoclaved technology. In addition, the production scheme of non-steamed and non-autoclaved PHC piles in the pearl river delta area is put forward, which conforms to the requirements of the low carbon, environmental protection and economic development.
