摘要
通过设置对比试验组,主要对比分析了不同长度及掺量下的剑麻纤维对普通水泥砂浆的流动度值、抗折强度及抗渗性能的影响,并深入研究了其作用机理。试验结果表明:剑麻纤维的长度与掺入量对普通水泥砂浆的物理性能有显著影响,掺量为4.5 kg/m3且长度为10mm的剑麻纤维能使水泥砂浆具有更好的流动度,28 d剑麻纤维水泥砂浆的抗折强度提高了29.5%,抗渗性能提高了45.9%,可满足实际工程的需要。
By setting the contrast test of the sisal fiber cement concrete and ordinary cement mortar with different length and content of sisal fibers, main analysis was made on the influence of fluidity, flexural strength and permea-bility resistance, and further study on its mechanism.The test showed that its length and content could make re-markable effect on the physical properties of ordinary cement mortar.When its dosage was 4.5 kg/m^3 and length was 10 mm, sisal fiber cement concrete has had a better fluidity than cement mortar, and 28d’ s flexural strength increased by 29.5%, permeability resistance increased by 45.9%, meeting the need of practical engineering.
