Concrete sustainable light and of high performance

Abstract

Theresearchis bornof the problematic environmental that is derived of the production, storage and generation in large quantities daily of waste industrial. This is proposed re-use of by-products plastics, wood and sludge of the paper industry for the manufacture of high performance (HP)-recycled concrete and lightweight concrete (ECOHUL). In addition nanomolecules of silica and active additions (fly ash) are used to increase the durability of the concretes. The main advantages of this new material are its low density, making it ideal for its function in areas seismic and a high impermeability. The use of aggregates light recycled varies substantially the density of them concretes and their resistance to compression (of form practically linear). However, and of form very positive, is has found that the dosages taken, with and without waste, is have behaved of form similar in them trials of durability-chlorides, carbonation and absorption capillary-highlighting the small carbonation, and low penetrations of chlorides (minor of 1 cm) in all them concretes studied. © Springer International Publishing AG 2017.
