摘　　要：为探索废渣粉对纤维砂浆耐久性及强度的影响,实验配制了20组不同水灰比、不同废渣粉掺量的纤维砂浆,对其进行孔隙率、吸水性及强度测试。结果表明,使用较大体积的废渣粉代替标准砂时会提高纤维砂浆的孔隙率,但吸水性及强度会得到改善;在孔隙率保持不变时,掺入废渣粉的体积越大,纤维砂浆的吸水性和强度结果越好;通过回归分析发现纤维砂浆的吸水性及强度均受孔隙率和废渣粉的共同影响。To explore the effect of adding waste stone powder on durability and strength of fiber mortar,20 mixes of fiber mortar with varying water/cement ratios and waste stone powder contents were prepared and tested for poriness,sorptivity and strength.The results showed that the use of a larger volume content of waste stone powder as standard sand replacement could increase the poriness,but the sorptivity and strength would be improved.When the poriness was a constant value,the larger the volume content of waste stone powder was,the better the sorpivity and strength of fibre mortar was.The regression analysis shows that the sorptivity and strength of fibre mortar are both affected by poriness and waste stone powder content.
