高性能混凝土梁正截面受力性能试验研究

通过14根模型梁的三分点加载试验研究，分析了掺加高效减水剂、粉煤灰、磨细矿渣和聚丙烯纤维对高性能混凝土梁正截面受力性能的影响，并将试验结果与有关混凝土结构设计规范的计算值进行了对比，初步验证了混凝土结构设计规范（GB50010-2002）对高性能混凝土梁的正截面设计计算的适用性，为大掺量外掺料高性能混凝土在工程上的应用提供了依据。

Experimental Study on Flexural Behavior of High Performance Concrete Beams

This paper expounds an experimental study on the flexural behavior of high performance concrete beams with tests of fourteen specimens,and makes a detailed analysis and comparison of the flexural capacity of high performance concrete beams respectively mixed with superplasticizer,fly ash,fine slag,and polypropylene fiber.A comparison is also made between the test results and the theoretical values.The comparison preliminarily proves the applicability of the Design Code for Concrete Structures(GB50010-2002) to the design and calculation of the flexural capacity of high performance concrete beams,thus providing a basic test support for the application of high performance concrete with large quantity of mineral admixtures.
