| Abstract: | The source and quality of aggregates in recycled concrete are analyzed. Through adding suitable chemical additives, the problems of high shrinkage and large demands of water are resolved. Then recycled concrete and usual concrete are compared in regard of the properties. The results indicate that the properties of recycled concrete are better, its strength is stable, and the economic benefits are obvious. The feasibility of utilizing high strength recycled concrete is analyzed,and the application areas of recycled concrete are discussed. Recycled concrete can replace usual concrete and be widely used in practical projects. |
