摘　　要：为探讨组合再生混凝土材料性能,制备了4种掺杂不同有机纤维的组合再生混凝土材料,分别测试其抗压强度、劈拉强度及抗折强度。结果表明,掺入有机纤维会降低材料的抗压强度,但会提高其劈拉强度及抗折强度。在此基础上制备了20种含有不同骨料的组合再生混凝土材料并计算其弹性模量。计算结果表明,不同骨料会对材料的弹性模量产生不同的影响(如硅灰的掺入会增强材料的弹性模量,钢纤维的掺入会降低材料的弹性模量)。In order to explore the performance of composite recycled concrete materials,the study prepares 4 kinds of composite recycled concrete materials doped with different organic fibers,and respectively tests their compressive,tensile and flexural strength.The results show that addition of organic fiber will reduce the compressive strength of the material,but increase the tensile and flexural strength.On this basis,20 kinds of composite recycled concrete materials containing different aggregates are prepared and their elastic modulus is calculated.The calculation results show that different aggregates have different effects on the elastic modulus of materials(for example,the addition of silica fume will enhance the elastic modulus of materials,and the addition of steel fiber will reduce the elastic modulus of materials).
