Wire gabions, or cages, can be filled with crushed concrete and then stacked together to provide economical retaining walls These gabions can also be used to protect embankments or other structures In such cases even bigger sizes of the crushed and recycled concreteAlthough recycled crushed concrete is used in pavements, the use of recycled crushed brick in pavement subbases has been limited because of lack of standardized guidelines or performancebased specifications for recycled crushed brick Another material that can be usedA Review of The Use Of Recycled Materials in Rigid

Feasible use of recycled concrete aggregates and

Molenaar and van Niekerk found that the mechanical characteristics of an unbound base course made with recycled concrete and masonry rubble were mainly governed by the degree of compaction Furthermore, Hansen and Angelo [5] found that it was possible to enhance the engineering properties of clayey soils for earthwork purposes by mixing the soils with recycled concrete fineThe three main types of material derived from most CDW are crushed concrete, crushed masonry, and mixed demolition debris After crushing and undergoing beneficiation in certified recycling plants, the resulting aggregates may be assigned to one of the four following categories 211 Recycled Concrete Aggregates (RCA)Properties and composition of recycled aggregates

Properties of concrete with recycled aggregates

In the last ten years, studies have focused on the application of RA coming from the treatment of debris mixed from concrete wastes and masonry These recycled mixed aggregates (RMA) contain ceramic particles (crushed clay bricks), and also certain quantities ofFor unbound use, the materials of Type 1 are required to contain more than 94% by weight of crushed concrete and/or natural aggregates In the type 2 category, the materials must consist of more than 90% concrete, masonry and natural aggregates In both categories the content of recycled asphalt is limited to less than 5%Release of major elements from recycled concrete
