在大多数情况下，纤维增强混凝土（FRC）仅包含一种类型的纤维。以适当的组合使用两种或多种类型的纤维有可能提高混凝土的机械性能，并产生性能协同作用。本文研究了弯曲和直接剪切下的这种纤维组合（通常称为杂交）。除了参考普通混凝土混合物外，还使用不同的纤维组合浇筑了几种单纤维增强混凝土混合物和双纤维增强混合复合材料混合物。研究了两种粗钢纤维和微纤维素纤维。进行了弯曲和直剪测试，并对结果进行了分析，以确定与各种纤维组合相关的协同作用（如果有的话）。该论文强调了负载配置对光纤协同的影响。 (C) 2013 Elsevier Ltd. 保留所有权利。
In most cases, fiber reinforced concrete (FRC) contains only one type of fiber. The use of two or more types of fibers in a suitable combination has the potential to improve the mechanical properties of concrete, and result in performance synergy. This combining of fibers, often called hybridization, is investigated in this paper under flexure and direct shear. Along with a reference plain concrete mix, several singlefiber reinforced concrete mixes and two-fiber reinforced hybrid composite mixes were cast using diverse fiber combinations. Two types of macro-steel fibers and a micro-cellulose fiber were examined. Flexural and direct shear tests were performed and the results were analyzed to identify synergy, if any, associated with various fiber combinations. The paper highlights the influence of load configuration on fiber synergy. (C) 2013 Elsevier Ltd. All rights reserved.
