为提升EP(环氧树脂)/橡胶混凝土的弯曲性能,以弹性改性剂含量和集料类型为试验因素,制备了不同类型的EP/橡胶混凝土,并采用统计分析法探讨了不同试验因素对EP/橡胶混凝土弯曲性能的影响。研究结果表明:集料类型与弹性改性剂含量相比,前者对EP/橡胶混凝土弯曲强度的影响显著,而后者的影响不明显;弹性改性剂含量和集料类型均对EP/橡胶混凝土弯曲变形量有显著影响,并且弯曲变形量与弹性改性剂含量的关系符合指数成长模型;当w(弹性改性剂)=30%(相对于EP/橡胶混凝土总质量而言)时,弹性/刚性集料体系的弯曲强度(为15.20 MPa)相对最高。
In order to improve the flexural properties of EP (epoxy resin) / rubber concrete, different types of EP / rubber concrete were prepared based on the content of elastic modifier and the type of aggregate, and the influence of different experimental factors Effect of flexural properties on EP / rubber concrete. The results show that the former has a significant effect on the flexural strength of EP / rubber concrete, while the latter has no obvious effect on the flexural strength of the EP / rubber concrete The amount of flexural deformation has a significant effect, and the relationship between the amount of flexural deformation and the amount of elastic modifier conforms to the exponential growth model; when w (elastic modifier) = 30% (relative to the total mass of EP / rubber concrete) The flexural strength of the rigid aggregate system (15.20 MPa) is relatively highest.
