摘要：通过正交试验研究了水胶比、砂胶比、粉煤灰掺量和剑麻纤维掺量对水泥基路面材料抗压性能和弯拉性能的影响。结果表明，高延性剑麻纤维水泥基路面材料的最佳配合比为：水胶比0.30、砂胶比0.4、粉煤灰掺量30%、剑麻纤维掺量0.5%，此时，试件的弯拉强度满足JTG D40—2011《公路水泥混凝土路面设计规范》的要求，且抗压强度较高，为66.62 MPa。 Abstract: The effects of water-binder ratio, sand-binder ratio, fly ash content and sisal fiber content on the compressive properties and flexural tensile properties of cement-based pavement materials were studied by orthogonal experiments. The results show that the optimal mix proportion of high ductility sisal fiber cement-based pavement material is: water-binder ratio of 0.30, sand binder ratio of 0.4, fly ash content of 30% and sisal fiber content of 0.5%, and the flexural tensile strength of the specimen meets the requirements of JTG D40—2011 Specifications for Design of Highway Cement Concrete Pavement, and the compressive strength is relatively high, which is 66.62 MPa.

摘要：为了改善水泥基材料的抗裂性能，满足建筑在加固、修复过程中对修补材料高韧性的需求，将耐碱玻璃纤维网、玻璃纤维方格布、玻璃纤维毡3种二维纤维分别掺入到聚合物水泥砂浆中，研究了不同二维纤维增强材料对聚合物水泥砂浆拉伸性能的影响，通过应力-应变曲线和拉伸破坏形态揭示了二维纤维增强材料对聚合物水泥砂浆的作用机理，通过对掺二维纤维增强材料聚合物水泥砂浆进行浸水和碱溶液处理，评价了其耐水、耐碱性能。结果表明：3种二维纤维增强材料均能提高聚合物水泥砂浆的拉伸强度与断裂伸长率，其中，玻璃纤维方格布对提升聚合物水泥砂浆的拉伸强度最有利；浸水和碱溶液处理均会影响掺二维纤维增强材料聚合物水泥砂浆的拉伸性能，其中，碱溶液处理更不利。 Abstract: In order to improve the crack resistance of cement-based materials and meet the requirements for high toughness of repair materials in the process of building reinforcement and repair, three two-dimensional fibers of alkali resistant glass fiber mesh, glass fiber checkered cloth, glass fiber felt were added into polymer cement mortar. The effect of different two-dimensional fiber reinforced materials on the tensile properties of polymer cement mortar was studied. The action mechanism of two-dimensional fiber reinforced materials on polymer cement mortar was revealed by stress-strain curve and tensile failure mode. The water resistance and alkali resistance of polymer cement mortar mixed with two-dimensional fiber reinforced materials were evaluated by soaking in water and alkali solution. The results show that the three kinds of two-dimensional fiber reinforced materials can increase the tensile strength and elongation at break of the polymer cement mortar, among which the glass fiber checkered cloth is most beneficial to the improvement of the tensile strength of polymer cement mortar. Both water immersion and alkali solution treatment will affect the tensile properties of polymer cement mortar mixed with two-dimensional fiber reinforced materials, among which alkali solution treatment is more unfavorable.

摘要：采用碱溶液浸泡和煮沸对椰壳纤维进行预处理，研究了处理时长对椰壳纤维吸水率、表面形貌、拉伸强度、弹性模量和表面静摩擦力的影响，并将预处理椰壳纤维掺入到水泥基材料中，研究了预处理椰壳纤维对水泥基材料拉伸性能和弯曲性能的影响。结果表明：与未处理椰壳纤维相比，煮沸处理2 h或碱处理5 h后，椰壳纤维的吸水率分别降低了40.25%、48.56%，拉伸强度分别降低了3.26%、5.54%，弹性模量分别降低了8.71%、3.32%，表面静摩擦力分别提高了209.41%、262.35%；采用浓度为15%的有机硅烷溶液浸泡预处理椰壳纤维后，再将预处理椰壳纤维分别按质量比m碱处理∶m煮沸处理=3∶1、m碱处理∶m煮沸处理=1∶1混掺时，水泥基材料的拉伸强度、弯曲强度较空白组分别提高了76.08%、68.04%。 Abstract: The coir fiber was pretreated by soaking and boiling in alkali solution, and the effects of treatment time on water absorption, surface morphology, tensile strength, elastic modulus and surface static friction of coir fiber were studied. The pretreated coir fiber was incorporated into cement-based material, and the effect of the pretreated coir fiber on the tensile and bending properties of cement-based material was studied. The results show that compared with the untreated coir fiber, after boiling for 2 h or alkali treatment for 5 h, the water absorption of coir fiber decreases by 40.25% and 48.56%, the tensile strength decreases by 3.26% and 5.54%, the elastic modulus decreases by 8.71% and 3.32%, and the surface static friction increases by 209.41% and 262.35% respectively. After the pretreated coir fiber is soaked in organosilane solution with the concentration of 15%, and then the pretreated coir fiber is blended according to the mass ratio of malkali treatmen∶mboiling treatment=3∶1 and malkali treatmen∶mboiling treatment=1∶1, the tensile strength and flexural strength of the cement-based material is increased by 76.08% and 68.04% respectively compared with the blank group.
