【摘要】 将制备的CaCO3改性PP纤维用于增强混凝土,并通过研究纤维增强后混凝土的抗冻融循环性能、抗渗透性能和抗冲刷性能,来研究增强混凝土的水工特性。结果表明,CaCO3改性PP纤维由于密度的提高和亲水性能的改善,导致对混凝土增强效果显著,增强混凝土的抗冻融循环性能、抗渗透性能和抗冲刷性能有显著提高,其中抗渗等级均超过W8,抗冲刷性能提高了33%～87%。
【Abstract】 In this paper,the concrete were reinforced by CaCO3 modified PP fiber.The freeze-thaw resistance, anti-permeability and anti-erosion performances of the concrete were studied.The results indicated that CaCO3 modified PP fiber played a significant role on reinforcement of concrete due to improvement of its density and hydrophilic property.Moreover,freeze-thaw resistance,anti-permeability and anti-erosion performances were greatly improved.Impermeability level of the modified concrete was beyond W8,and anti-erosion performance was improved by 33%-87%.
