Abstract
A current promising way towards sustainable construction is the concrete construction and demolition waste recycling. Indeed, the use of recycled concrete aggregates instead of natural aggregates promotes the natural resources conservation and reduces the environmental impact of concrete. This paper presents the results of an experimental investigation on the mechanical properties of concretes with recycled aggregates obtained from two different parent concretes, belonging to the structure of old Cagliari football stadium. The main target of this work is to verify the effectiveness of adopting concrete debris as recycled aggregates in the new structural concrete. The influence of parent concrete on the characteristics of coarse recycled aggregates and of new structural concrete with these aggregates are investigated. Modulus of elasticity, compressive strength, splitting tensile strength of recycled concretes have been assessed and discussed in order to highlight the role of parent concrete.File | Size | Format | |
