表层渗透试验方法对纤维高性能混凝土的适用性

Applicability of Near-Surface Permeation Test Method to Fiber-Toughened High-Performance Concrete

本文进行了Germanns表层渗透试验和氯离子渗透试验,探讨了表层渗透实验对测试纤维高性能混凝土的适用性,以及纤维对混凝土渗透性的影响。试验结果表明:Germanns表层渗透试验能够反映水胶比、纤维种类和纤维掺量对混凝土渗透性的影响,适用于高性能混凝土渗透性的测试;其试验结果和氯离子渗透试验结果有较好的相关性。

This research was aimed to identify applicability of a specific near-surface permeation test method,i.e.the Germanns water permeation,to permeability of fiber-toughened high-performance concrete.The experimental results indicate that the Germanns water permeation test can reflect the influence of water/cement ratio,type and content of fiber on the concrete s permeability and suitable for testing permeability of fiber-toughened high-performance concrete.The data of Germanns water permeation test can be well correlated with those of the chloride ion penetration test.
