Abstract

AbstractAn important aspect of sustainable construction is the recycling or reuse of the construction and demolition (C&D) waste to maintain a friendly green environment. The wide range of building materials and its compositions inhibit the efficient waste management and complete recycling after demolishing. To contribute in this field and promote the use of local waste as 100% alternative coarse aggregate in construction industry, an experimental program was carried out using samples of main Iraqi building C&D waste. The types of aggregate used represent the three main constituents within recycled aggregates: unbound stone, crushed concrete, and crushed brick. Tests for mechanical properties of different types of recycled aggregate included crushing value and abrasion resistance. Using multilinear correlation analysis, the influences of these aggregate characteristics and other parameters on the properties of recycled aggregate concrete were evaluated. The results showed that the performance of the concr...
