| 摘 要： | 在水泥砂浆制品中掺加适量的表面改性芳纶纤维。可以显著提高水泥砂浆制品的抗折强度。与空白水泥砂浆试样相比，当掺加1．5kg／m^3表面改性芳纶纤维时，水泥砂浆试样28d抗折强度提高了30．28％。初步探讨了掺加表面改性芳纶纤维提高水泥砂浆性能的机理。

| Abstract: | Filling moderate amount of aramid fiber can enhance cement mortar＇s flexural strength. Compared with cement with no fiber content, when Kevlar fiber is added by 1.5 kg/m^3,the flexural strength of 28 days is increased by 30.28%. The reinforcement mechanism of filling modified aramid fiber on cement mortar＇s performance is explored. |
