Title:	Relationship between gas adsorption and the shrinkage and creep of recycled aggregate concrete
Author:	Gómez Soberón, José Manuel Vicente
Other authors:	Universitat Politècnica de Catalunya. Departament de Construccions Arquitectòniques II
Abstract:	In this work, it is described an experimental analysis of specimens of recycled concrete (RC) with replacement of natural aggregate with recycled aggregate originating from concrete (RCA). An experimental analysis to obtain the shrinkage and creep properties (basic and by drying) of RC was carried out. The replacement fraction of natural aggregate with RCA were 0%, 15%, 30%, 60% and 100% and the test conditions were 50% RH and 20 °C. The results of these trials were compared with mercury intrusion porosimetry tests (MIP) and gas adsorption (nitrogen), at 90 days. In the results, an increase in the shrinkage and creep properties of the RC with respect to conventional concrete was observed, while porosity values increased. However, the deformation evolution in the time is similar to conventional concrete.
