A proposal has been put forward for a recycling scheme aimed at reusing the main components of construction waste,including concrete,glass,and steel.However,an effective method for recycling solid waste sand powder,which is the primary by-product in this process,is currently lacking.This paper provides a comprehensive review of the impact of physical and chemical properties of solid waste sand powder on both mechanical and durability aspects of recycled concrete.The results indicate:The hydration reaction activity of solid waste sand powder is mainly controlled by the characteristics and proportion design of micro-powder,and the water-binder ratio of concrete,the replacement ratio of sand powder,particle size and fineness of recycled fine powder significantly affect the mechanics and durability of recycled concrete.
