abstract = {The construction field has contributed to environmental degradation, producing a high amount of construction and demolition waste (C&D waste) and consuming large volumes of natural resources. In this context, recycled concrete (RC) has been recognised as a means to preserve natural resources and reduce space for waste storage. During the last decades, many researchers have developed works studying different recycled concrete properties. This review focuses on structural RC made with coarse recycled aggregate from concrete waste. The main objective is to provide a state of the art report on RC's properties and an analysis on how to predict them taking into account relevant research works. Moreover, the study tries to collect and update RC findings, proposing equations to define RC's performance, in terms of mechanical strength, modulus of elasticity, stress-strain, creep and shrinkage. © 2018 CSIC.},

abstract = {This work studies the fresh behaviour of self-compacting recycled concrete (SCRC) with different replacement percentages of recycled concrete coarse aggregate (20, 50 and 100%). To control the high absorption of recycled aggregate, three different mixing methods are also used in each studied concrete: M1 (dry aggregate and extra water), M2 (pre-soaked aggregate) and M3 (aggregate with a 3% of natural moisture and extra water). The fresh-state properties are measured with empirical and rheological tests, both carried out at 15, 45 and 90 min from the water-cement contact. Results obtained lead to conclude that rheology is the best tool to control fresh state behaviour of SCRC mixes and that Bingham 5-lowest is the suitable model to describe their rheological behaviour. Additionally, it has been concluded that the best method to produce SCRC is to compensate the recycled aggregate absorption during mixing using an extra quantity of water. With this method, self-compacting behaviour can be maintained with all replacement percentages until 45 min, and even until 90 min when the replacement ratio does not exceed 50%. Moreover, the use of the recycled coarse aggregate with a previous moisture content involves a greater difficulty to control workability and rheology than its use in dry-state condition. © 2017 Elsevier Ltd},

abstract = {In this work the influence of the substitution of 100% of natural coarse aggregate with recycled coarse aggregate has been analysed in order to know the behaviour of the structural concrete in one particular aspect: that is, the behaviour of the recycled concretes under sustained load. To know the behaviour under sustained load, tests under very low loading rate were carried out, using concretes with 100% of recycled coarse aggregate. The results indicated that the ratio of strength under very low loading rate over strength under standard loading rate in compression and in tension is very similar in conventional and recycled concretes. © 2011 Elsevier Ltd.
