| 摘 要： | 研究了钢纤维和有机合成纤维对高性能轻骨料混凝土的增强增韧效果。结果表明,掺入钢纤维具有较好的增强增韧效果、弯曲韧度系数最高可提高14倍,但表观密度相应增大;掺入有机合成纤维可以在不增加轻骨料混凝土表观密度、保证其高强度的基础上,有效地改善轻骨料混凝土的韧性。

| Abstract: | This paper studies effects of steel fibers and synthetic fibers on mechanical properties of high performance lightweight aggregate concrete(LWAC). Results show the introduction of steel fibers can reinforce both strength and toughness of LWAC,and its flexural toughness index can be improved 14 times at the most,but its apparent density will be increased correspondingly.By introducing synthetic fibers,the toughness of LWAC can be improved effectively,and both its low apparent density and high strength will be maintained. |
