摘　　要：以新型短切玄武岩纤维制备纤维水泥砂浆,借鉴水泥胶砂流动度的试验方法,研究玄武岩纤维的长度和掺量等参数对水泥砂浆流动性的影响。试验结果表明:纤维掺量越大,其比表面积(FSS)越大,纤维水泥砂浆的流动性越低;对于相同纤维掺量,虽然FSS相同,但18 mm(lf)纤维水泥砂浆比12 mm(lf)纤维水泥砂浆的流动性更大。根据实验结果,进一步探讨了现行纤维间距理论中存在的一些问题。The specimens of the fiber cement mortar with chopped basalt fiber as raw material are molded and the fluidity experiments are conducted by the means of the general cement mortar fluidity experiment. The experimental result shows that the fluidity of the basalt fiber cement mortar becomes less as the fiber content and the FSS increasing, the fluidity of the 18mm length fiber cement mortar is more than that of the 12mm length fiber cement mortar when they have the same fiber content. Then, some problems about the fiber spacing theory are discussed based on the experimental result.
