Encapsulation of Recycled Aggregates Using Mixed Construction and Demolition Wastes
Abstract Construction and demolition waste (RCD) represents an important contribution to socio-economic development with respect to the depletion of non-renewable resources, where aggregates are approximately 60–75% of the concrete mix and can be reused, therefore the present investigation Its purpose is to study the behavior of hydraulic concretes by encapsulating the intermediate fraction of recycled aggregates. For this purpose, the materials to be used were characterized, being governed, in the case of aggregates, by NC 251 “Aggregates for hydraulic concretes. Requirements.” The fraction of 5–9 mm was encapsulated with the objective that this thin layer covers the pores of the aggregate that cause a high absorption of water, affecting the properties of the concrete. For this we tested with LC3 cement and two proportions of these materials (60 and 40 kg/m3) deciding among them the best mixture for the encapsulation. From this concrete was made, demonstrating that said encapsulation, increases the compressive strength of it.
