La utilización de agregados reciclados provenientes de residuos de construcción y demolición (RCD) en nuevas obras civiles se considera el camino hacia la sostenibilidad. Esta investigación presenta la posibilidad del uso ...
Constitutive theory for Recycled Aggregate Concretes subjected to high temperature
(Elsevier, 2016-05)
The use of recycled aggregates in concrete to partially substitute the natural ones has strongly increased in the last decades. Due to both, environmental and economical reasons, a relevant and increasing proportion of the ...
Mechanical performance of eco-friendly concretes with volcanic powder and recycled concrete aggregates
At present, reducing the environmental impact of the construction industry is a major subject of study. In terms of the use of recycled concrete aggregates (RCA), most recently conducted studies have shown that the use of ...
High density flux of Co nanoparticles produced by a simple gas aggregation apparatus
(AMER INST PHYSICS, 2010)
Gas aggregation is a well known method used to produce clusters of different materials with good size control, reduced dispersion, and precise stoichiometry. The cost of these systems is relatively high and they are generally ...
Incorporação conjunta de resíduos de EVA e EPS em concreto leve sem função estrutural: avaliação da mistura dos resíduos e influência da pré-hidratação
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de AmbientalEngenharia AmbientalUTFPR, 2020-12-02)
Several environmental impacts are caused due to the extraction of natural resources, low levels of reuse of waste and the high rate of irregular disposal. In this sense, the highlights are Vinyl and Ethylene Acetate (EVA) ...
