The use of natural hemp fabric for strengthening existing concrete columns was investigated in this work. The results presented in this paper were based on an experimental setup analysing the efficiency of natural hemp fibres for the confinement of existing concrete columns. The variables considered were the number of hemp fabric layers, the column length/diameter ratio and the presence of transverse reinforcement. Uniaxial compression tests were performed on 36 specimens. The axial stress–strain curves ductility, and failure modes were analysed. The test results indicate that the three variables considered had significant effects on the confined columns’ strength and post-peak behaviour.

麻织物包裹混凝土柱的性能研究

在这项工作中研究了使用天然大麻织物加强现有混凝土柱。本文中提出的结果基于一个实验装置，该实验装置分析了天然大麻纤维对现有混凝土柱的限制的效率。考虑的变量是大麻织物层数、柱长/直径比和横向钢筋的存在。对 36 个试样进行了单轴压缩试验。分析了轴向应力-应变曲线的延展性和失效模式。测试结果表明，所考虑的三个变量对受限色谱柱的强度和峰后行为有显着影响。
