The properties of hardened Recycled Aggregate Concrete for use in structural work, particularly in prestressing where a minimum strength is required to sustain the precompression, have been investigated. A large number of mixes (more than thirty) suitable for a pre-cast use of RAC were tested to study the influence of different types of cement and water/cement ratio. Compressive strength, tensile strength, flexural strength and modulus of elasticity were measured at various test ages. It was found that it was possible to design recycled aggregate concrete capable of developing up to 50 MPa strength.
