自密实混凝土及其性能试验研究

Test and Study of Self-compacted Concrete and Its Performance

缅甸瑞丽江一级水电站引水系统压力管道段管壁外衬砌混凝土,考虑使用自密实混凝土进行泵送或溜管浇筑,为此须对自密实混凝土的配合比选择、工作性能及力学性能进行试验研究与论证,以保障压力管道段管壁外衬砌自密实混凝土的顺利浇筑和质量优良。

To place external lining concrete of the penstock of the power tunnel system with self- compacted concrete delivered by pump or chute it is necessary to select a proper mix proportion of the self- compacted concrete and to carry out test, study and verification of its performance and mechanical property so that the self- compacted concrete could be placed in a successful way and its quality could be ensured.
