Preparation of High-Performance Brick from Construction and Demolition Waste

Abstract:

Recycled aggregate prepared from construction and demolition waste (C&DW) through sorting, crushing and screening process was mixed with an eco-cement (mainly from high calcium fly ash, granulated blast-furnace slag and clinker), antifreeze additives and water, forming high-performance load bearing brick. The product prepared conforms to GB/T21144-2007 (Concrete Solid Brick, China National Standards) with excellent freeze-thaw resistance and high strength. The effects of water-solid ratio and cementing material content on the performance of the product were investigated.
