摘要
通过碳纳米管水泥净浆复合材料力学试验,考察不同龄期和不同碳纳米管掺量对水泥基复合材料抗折、抗压强度的影响,以及不同龄期下不同碳纳米管掺量的水泥基复合材料试件的增韧特性。结果表明,掺入碳纳米管可以有效改善水泥基复合材料的脆性;当碳纳米管掺量为0.10%时,水泥基复合材料试件的抗折、抗压强度有较明显提高;当碳纳米管掺量为0.05%时,水泥基复合材料试件的韧性指数较大。
The effects of Carbon Nanotubes to cement-based composites are investigated. The flexural strength and the compressive strength of the CNTs cement-based composites under different content and different age are tested and the toughness indexes are analyzed. The results show that CNTs have a positive effect on the brittle failure of cement-based composites, the compressive strength and flexural strength of cement-based composites with 0.10% CNTs are significantly increased, and the toughness index of cement-based composites with 0.05% CNTs is relatively higher.
