掺风电叶片固废料3D打印混凝土的打印性能与力学性能试验研究
Printing Performance and Mechanical Properties of 3D Printed Concrete Mixed with Wind Turbine Blade Solid Waste
摘要
Abstract
In order to study the effect of wind turbine blade solid waste(WTBW)on the performance of 3 D printed concrete,this study mixed two kinds of WTBW into 3D printed concrete at different replacement ratios,and then the printing performance and mechanical properties of 3D printed concrete were tested.By analyzing the pore structure,the effect of WTBW on the performance of 3D printed concrete was explained from the microscopic point of view.The results show that the printing performance of concrete is the best when the WTBW replacement rate of powder type is less than 10％(mass fraction)and the WTBW replacement rate of fibrous villous type is less than 5％(mass fraction).The mechanical properties of the 3D printed concrete mixed with WTBW are obviously anisotropy.Compared with the control group,the 28 d compressive strength of the 3D printed concrete mixed with 10％powder WTBW increases by 7.28％,while the flexural strength and splitting tensile strength are not significantly improved,the mechanical properties of 3D printed concrete mixed with 5％fibrous villous type WTBW decrease,and the addition of WTBW can improve the significant anisotropy of concrete.The analysis of pore structure shows that powder WTBW plays a role of filling compaction in concrete and can effectively reduce the concrete porosity,while fibrous villous type WTBW increases the concrete porosity.关键词
