再生混凝土推广制约因素探析

Analysis on the Restrictive Factors of the Popularization of Recycled Concrete

在以查阅相关文献为主、相关调研为辅的基础上,得到28个影响再生混凝土推广的制约因素,并发放问卷获取相关数据。通过建立分析框架,以熵权法计算确定各制约因素的权重,再将各制约因素的权重与认同度平均值相结合计算制约因素完善度的面积大小,确定各指标的优先改进顺序,最后绘制扇形雷达图直观分析各制约因素对再生混凝土推广的影响顺序,明确改进优先级。研究发现:对资源化利用科研投入不足、建筑垃圾集中困难、建筑垃圾监督信息化程度低、资源化利用宣传教育不足、思想观念和认知不足需优先改进。

On the basis of referring to relevant literature and supplemented by relevant research,28 restrictive factors affecting the promotion of recycled concrete were obtained,and questionnaires were issued to obtain relevant data.By establishing an analysis framework,the entropy weight method is used to calculate and determine the weight of each constraint factor,and then the weight of each constraint factor is combined with the average value of the recognition degree to calculate the area size of the perfection degree of the constraint factor,and the priority improvement order of each indicator is determined.The fan-shaped radar chart intuitively analyzes the influence sequence of each restrictive factor on the promotion of recycled concrete,and defines the improvement priority.The research found that:insufficient investment in scientific research on resource utilization,difficulty in concentrating construction waste,low level of construction waste supervision informatization,insufficient publicity and education on resource utilization,and insufficient ideology and cognition should be prioritized for improvement.
