Specifications of concrete with recycled aggregates

Published in François de Larrard, Horacio Colina, Concrete Recycling, 2019

Eurocode 2 (EN 1992) describes the principles and the requirements for safety and durability of concrete structures using the limit state concept. It only deals with requirements for mechanical strength and fire resistance. Properties of concrete are given in section 3 of Eurocode 2 part 1-1. This section includes compressive and tensile strength (fck and fctm), elastic modulus (Ecm), shrinkage (εcs), and creep (Φ (t,t0)). It is well established that these three latter properties as well as fctm in a less extent may be modified, for the same compressive strength, when RA replaced NA in concrete (see Chapters 10 and 11). It should then be necessary to provide the Eurocode 2 with modified models to account for the influence of RA on these properties.

Life-cycle concepts and methods are necessary for a rational approach to seismic design of structural systems considering the detrimental effects of ageing and deterioration of materials and components under uncertainty (Biondini & Frangopol, 2016). For reinforced concrete (RC) structures exposed to corrosion, the check of durability requirements is usually limited to the control of the quality of materials and to the compliance of technical prescriptions such as the minimum cover depth (CEB, 1992; CEN-EN, 1992-1, 2004; fib, 2006).
