Recycling fresh concrete waste: A review

摘要

Disposal of fresh concrete waste is a worldwide problem. In recent years, many studies have claimed that fresh concrete waste from a reclaiming system can be efficiently recycled into concrete. This paper gives a comprehensive review of the characteristics and applicability of fresh concrete waste in phase of slurry wastewater, fresh paste, and recycled solids. The effects of fresh concrete waste in the three phases on workability, strength, and durability such as permeability, water absorption, shrinkage, and acid resistance of concrete have also been reviewed in this paper.
