| Abstract: | In
this paper, a methodology for prediction of long-term properties of recycled
aggregate concrete is presented, based on an extensive literature review of
international experimental campaigns on this type of environment-friendly concrete.
The methodology presented is based on the previous determination of the main
properties of the aggregates (density and water absorption), primary and
recycled, coarse and fine, and alternatively the 7-day compressive strength of
concrete made with those aggregates. The methodology is validated, based on a
graphical analysis of the most important properties of hardened concrete
(compressive strength, modulus of elasticity, splitting and flexural tensile
strength, shrinkage, creep, water absorption, and carbonation and chloride
penetration depth). It is concluded that the methodology can predict the
long-term performance of recycled aggregate concrete as compared with an
equivalent conventional concrete and that this prediction can be used to adapt
structural design to this material. |
