摘要

据报道，剑麻是一种很有前途的水泥复合材料纤维。剑麻纤维增强混凝土（SFRC）和钢剑麻纤维加强混凝土（SSFRC）的耐久性尚未报道。对纤维水泥复合材料进行了吸水性、快速氯离子渗透性和酸侵蚀试验。使用总体积为0.50%、1.00%、1.25%和1.50%的钢、聚丙烯和剑麻纤维。在SFRC中，当剑麻含量为1.50%时，吸水率提高了76%，但当剑麻浓度为0.2%时，SSFRC的吸水率降低到30%。SFRC和SSFRC的渗透率分别提高了1.69%和2.09%。SFRC的体积损失最高，为6.52%。SSFRC说明了其对质量损失和抗压强度损失的抵抗力。总之，任何形式的未经处理的剑麻都不利于耐用的纤维混凝土结构。

Durability Study of Hybrid Fiber Reinforced Concrete

Sisal has been reported as one of the promising fibers for cement composite applications. The durability of sisal fiber reinforced concrete (SFRC) and steel sisal fiber reinforced concrete (SSFRC) have not been reported. Water absorption, rapid chloride permeability, and acid attack tests are conducted on fibrous cement composites. Steel, polypropylene, and sisal fibers with a total volume of 0.50%, 1.00%, 1.25%, and 1.50% were used. Sisal at a content of 1.50% in SFRC increases the water absorption by 76%, but it is reduced to 30% for SSFRC with 0.2% of sisal content. SFRC and SSFRC show the increased permeability of 1.69% and 2.09% respectively. SFRC experiences the highest volume loss of 6.52%. SSFRC illustrates the resistance to the mass loss and compressive strength loss. In conclusion, untreated sisal in any form is found to be not advantageous for durable fibrous concrete structures.
