摘   要：研究了苎麻纤维（RF）的长度（1、2、3、4 cm）和掺量（0、0.15%、0.30%）对橡胶混凝土力学性能、抗冲击性能、吸水率和抗氯离子渗透性能的影响，并进行了微观机理分析。结果表明：掺入适量合适长度的RF可以有效改善橡胶混凝土的综合性能；对于力学性能，RF的最佳掺量为0.15%，长度为2~3 cm；对于抗冲击性能，RF的最佳长度和掺量分别为3 cm和0.30%；对于吸水率，RF的最佳长度和掺量分别为1 cm和0.15%；对于抗氯离子渗透性能，RF的最佳长度和掺量分别为4 cm和0.30%；RF与混凝土基体间的黏结性较好，能有效发挥桥接裂缝和传递内力的作用。Abstract: The effects of the length (1, 2, 3, 4 cm) and content (0, 0.15%, 0.30%) of ramie fiber (RF) on the mechanical properties, impact resistance, water absorption rate, and chloride ion penetration resistance of rubber concrete were studied, and the microscopic mechanism analysis was conducted. The results indicate that adding an appropriate content of RF with suitable length can effectively improve the comprehensive performance of rubber concrete. For mechanical properties, it is recommended that the optimal content of RF be 0.15% and the length be 2~3 cm. For impact resistance, the optimal length and content of RF are 3 cm and 0.30%, respectively. For water absorption rate, the optimal length and content of RF are 1 cm and 0.15%, respectively. For chloride ion penetration resistance, the optimal length and content of RF are 4 cm and 0.30%, respectively. The adhesion between RF and concrete matrix is good, which can effectively bridge cracks and transfer internal forces.

摘   要：采用地聚物和再生骨料制备了透水混凝土，并用地聚物净浆对再生骨料进行了表面强化处理，设计了2组试验，分别研究了目标孔隙率及水胶比、表面强化再生骨料对地聚物再生骨料透水混凝土（GRAPC）性能的影响。结果表明：对于A组GRAPC（未表面强化的再生骨料）而言，当水胶比相同时，随着目标孔隙率的增加，GRAPC的坍落度增加，抗压强度、抗折强度降低，透水性能提高，有效孔隙率增加；当目标孔隙率相同时，随着水胶比的增加，GRAPC的坍落度增加，抗压强度、抗折强度先增后降，透水性能降低，有效孔隙率降低。对于B组GRAPC（表面强化再生骨料）而言，随着目标孔隙率的增加，各组GRAPC的坍落度增加，抗压强度、抗折强度降低，透水性能提高，有效孔隙率增加；附加用水组GRAPC（未表面强化的再生骨料）的坍落度明显高于骨料强化组，抗压强度、抗折强度、透水性能、有效孔隙率均低于骨料强化组。GRAPC的透水系数和有效孔隙率、抗压强度和抗折强度均呈正相关关系，透水系数和抗压强度呈负相关关系。Abstract: Pervious concrete was prepared using geopolymer and recycled aggregate, and the recycled aggregate was strengthened with geopolymer slurry. Two sets of experiments were designed to study the effects of target porosity and water binder ratio, surface strengthened recycled aggregate on the performance of geopolymer recycled aggregate pervious concrete (GRAPC). The results show that for group A GRAPC(recycled aggregate without surface strengthen), when the water binder ratio is the same, with the increase of the target porosity, the slump of GRAPC increases, the compressive strength and flexural strength decrease, the pervious performance increases, and the effective porosity increases. When the target porosity is the same, with the increase of the water binder ratio, the slump of GRAPC increases, the compressive strength and flexural strength first increase and then decrease, the pervious performance decreases, and the effective porosity decreases. For group B GRAPC(surface strengthened recycled aggregate), as the target porosity increases, the slump of each group GRAPC increases, the compressive strength and flexural strength decrease, the pervious performance improves, and the effective porosity increases. The slump of the additional water group GRAPC(recycled aggregate without surface strengthen) is significantly higher than that of the aggregate strengthening group, while the compressive strength, flexural strength, pervious performance, and effective porosity are all lower than those of the aggregate strengthening group. The permeability coefficient and effective porosity, the compressive strength and flexural strength of GRAPC are positively correlated, while the permeability coefficient and compressive strength are negatively correlated.
