高速公路预应力梁压浆料双掺技术研究

Research on double permeability of pressure slurry of prestressed beams on expressways

依托漳永高速公路A8标中的桥梁工程,基于最小水胶比理论,从经济和实用性两方面考虑,在进行大量配合比设计、现场试验、理论分析和实际应用的基础上,对高速公路预应力梁压浆料双掺技术开展了研究工作,最终得出了一些有意义的结论。

Based on the bridge project in A 8 Bidding of Zhangzhou-Yong, an Expressway, the paper researches the double permeability of pres-sure slurry of prestressed beams on expressways based on a number of proportional ratio designs, site tests, theoretic analysis and factual applica-tion from the money-saving and practice with the minimal water-binder ratio, and achieves some valuable conclusions.
