AB Recycled Concrete Aggregate (RCA) has greater elasticity than natural aggregate, due to the presence ofadhered hydrated mortar in the coarse fraction, and mortar particles in the fine fraction. To evaluate thisaspect under temperature variations, four Self-Compacting Concretes (SCC) made with 100% coarse and/or fine RCA were subjected to cyclical temperature variations between 70  C and 20  C and between 15  C and 20  C. The addition of RCA, especially in the coarse fraction, increased the thermal deformability, although the difference tended to decrease with the number of cycles, especially in positive temperature variations. This study concludes that the traditional upper limit of the linear thermal expansioncoefficient for concrete (1.210 5  C 1) is also suitable when RCA is incorporated.
