Abstract

The demand for durable, resistant, and high-strength structural material has led to the use of fibers as reinforcing elements. This paper presents an investigation into the inclusion of chopped steel wool fibers (CSWFs) in cement to form a high-flexural strength cementitious composite matrix (CCM). CSWFs were used as the primary reinforcement in CCM at increments of 0.5 wt%, from 0.5-6 wt%, with ratios of cement to sand of 1:1.5 and water to cement of 0.45. The inclusion of CSWFs resulted in an excellent optimization of the physicomechanical properties of the CCM, such as its density (2.302 g/cm), compressive strength (61.452 MPa), and maximum flexural strength (10.64 MPa), all of which exceeded the performances of other reinforcement elements reported in the literature.

摘要

对耐用、耐腐蚀和高强度结构材料的需求促使人们使用纤维作为增强元素。本文对在水泥中加入短切钢丝棉纤维（CSWFs）以形成高抗弯强度水泥基复合材料基体（CCM）进行了研究。CSWFs被用作CCM中的主要增强材料，添加量从0.5 wt%到6 wt%，增量为0.5 wt%，水泥与沙子的比例为1:1.5，水与水泥的比例为0.45。CSWFs的加入使CCM的物理力学性能得到了极佳的优化，如密度（2.302 g/cm）、抗压强度（61.452 MPa）和最大抗弯强度（10.64 MPa），所有这些性能均超过了文献中报道的其他增强元素的性能。
