摘要
公路改扩建工程中会产生大量的废旧混凝土,对其进行破碎、筛分等处理后得到的再生集料与天然集料相比,物理性能差别不大,可应用于再生混凝土、路面基层、再生砖等领域。具有节约资源、保护环境等效果,同时还有较好的经济、社会和生态环境效益。
A large amount of waste concrete will be produced in highway reconstruction and expansion projects. Compared with natural aggregates,recycled aggregates obtained from crushing and screening of waste concrete have little difference in physical properties,which can be applied in the fields of recycled concrete,pavement base and recycled brick.It has the effects of saving resources and protecting the environment,as well as good economic,social and ecological environmental benefits,and has the value of popularization.
