Estudo das propriedades de concretos com substituição parcial de agregado natural por RCD
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia de Produção CivilUTFPR, 2015-12-03)
The civil construction sector is one of those responsible for waste generation and the extraction of natural resources. In order to contribute to sustainability, there is the importance of studies on the properties of ...
On the classification of mixed construction and demolition waste aggregate by porosity and its impact on the mechanical performance of concrete
(SPRINGER, 2010)
The properties of recycled aggregate produced from mixed (masonry and concrete) construction and demolition (C&D) waste are highly variable, and this restricts the use of such aggregate in structural concrete production. ...
Comparative carbon emission assessments of recycled and natural aggregate concrete: Environmental influence of cement content
(ElsevierNL, 2021)
This work examines the environmental and geochemical impact of recycled aggregate concrete production with properties representative for structural applications. The environmental influence of cement content, aggregate ...
Durable performance of recycled aggregate concrete in aggressive environments
(American Society of Civil Engineers, 2020-07)
Recycled aggregate concrete is an eco-friendly material that is increasingly being used in new constructions. Nowadays, this application is mainly limited by user?s lack of confidence, as coarse recycled aggregate (CRA) ...
Análise da viabilidade técnica de utilização de resíduos de concreto oriundos da pré-fabricação como agregado graúdo para a produção de novos concretos
(Universidade do Vale do Rio dos Sinos, 2011-03-25)
The concern about the environment and the lack of natural resources has led all segments of society to the search for more sustainable alternatives of growth. In this run for environmental welfare, the recycling of material ...
