Influence of Textile Fiber in the Mechanical Characteristic of Hybrid Fiber Reinforced Concrete

ABSTRACT

The early growth of micro-cracks develops due to plastic and dry shrinkage weakens conventional concrete’s mechanical properties; which can be improved by introducing discrete and randomly oriented natural and synthetic textile fibers, like sisal, banana, and nylon in concrete matrix. Previously, researchers focused only on double hybrid fiber reinforced concrete, whereas triple hybrid fiber reinforced concrete requires a further behavioral study on fiber reinforced concrete’s mechanical characteristics. In this paper, we investigate the mechanical properties induced by the addition of discrete and randomly oriented textile fibers to the cementing matrix in a varying volume fraction of 0.5% v_f to 2% v_f along with 1% v_f triple hybrid. BF0.5% v_f, SF1.5% v_f, NF1% v_f & HFRC (SF0.5BF0.25NF0.25) % v_f gives optimum fiber dose in the composite. As a rule, the specimens gain impressive compressive strength. Most of them exhibit enhanced tensile properties compared to the control specimen. These developments signal the advent of an eco-friendly, economical, and highly sustainable alternative to conventional concrete.

摘要

塑性收缩和干缩导致微裂缝的早期扩展削弱了常规混凝土的力学性能; 可以通过在混凝土基体中引入离散和随机取向的天然和合成纺织纤维 (如剑麻, 香蕉和尼龙) 来改善. 以前, 研究人员只关注双混杂纤维增强混凝土, 而三混杂纤维增强混凝土; 需要对纤维增强混凝土的力学特性进行进一步的行为研究. 本文研究了在0.5% v_f 至2% v_f 的不同体积分数下, 向胶结基质中添加离散和随机取向的纺织纤维以及1% v_f 三元混杂纤维所引起的力学性能. BF0.5% v_f, SF1.5% v_f, NF1% v_f 和HFRC (SF0.5BF0.25NF0.25) % v_f 在复合材料中提供最佳纤维剂量. 通常, 试样获得了令人印象深刻的抗压强度. 与对照试样相比, 大多数试样表现出增强的拉伸性能. 这些发展标志着一种环保, 经济和高度可持续的传统混凝土替代品的出现. (此处插入图形摘要).
