自密实混凝土工作性测试方法及其评价标准研究进展

PROGRESS IN RESEARCH ON TEST METHODS OF WORKABILITY OF SELF-COMPACTING CONCRETE AND EVALUATION STANDARDS

自密实混凝土是高性能混凝土发展方向,国内外对自密实混凝土的测试方法开展研究,并制定相应的标准,测试方法种类和评价标准种类繁多,尚未取得统一。本文对国内外工作性测试方法与评价标准进行总结与分析,指出自密实混凝土工作性测试与评价方法的发展方向。

The self-compacting concrete is the developing trend of high-performance concrete.whose test methods have been studied both at home and abroad and the corresponding standards were worked out.The test methods and evaluation standards vary in their sorts.The test methods of workability and evaluation standards were summarized and analyzed;the developing direction of testing & evaluating methods of workability of self-compacting concrete was pointed out.
