本文介绍了乳胶改性对含有硅灰的碳纤维增强砂浆之性能特征的影响。在国外的研究中使用了两种苯乙烯-丁二烯乳胶。据观测,乳胶改性提高了胶结料与碳纤维的粘结力。乳胶改性的纤维水泥复合物同未改性者相比较,其吸水率和干缩率均降低了,而弯曲延性则提高了。乳胶改性的碳纤维增强砂浆具有较高的抗冻性,而且在耐酸性方面有明显提高。 This article describes the effect of latex modification on the performance characteristics of carbon fiber reinforced mortars containing silica fume. Two styrene-butadiene latexes were used in a foreign study. It has been observed that latex modification increases the bond between the binder and the carbon fiber. Latex modified fiber cement composites with unmodified compared to its water absorption and shrinkage decreased, while the bending ductility increased. Latex modified carbon fiber reinforced mortar with high frost resistance, but also significantly improved in acid resistance.
