Influência dos agregados reciclados nas propriedades reológicas e mecânicas do concreto autoadensável
(2018-01-01)
Recycling of mineral fraction of construction and demolition wastes (CDW), in form of aggregates, is seen as an alternative to reduce environmental impacts caused by construction. Recycled aggregates present higher water ...
Recycled Concrete: Mixture Variations to Improve its Durability
(Nova Science Publishers, 2017)
Recycled concrete presents a higher porosity than traditional concrete, making it more susceptible to external agents and favoring the development of different pathologies in reinforced concrete structures. In particular, ...
Comportamento de pilares mistos preenchidos com concreto de resíduos de concreto submetidos a compressão axial centrada: efeito do teor de substituição e da forma de aplicação da força
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2020-02-20)
Seeking to mitigate the environmental impact of civil construction, investigations focused on concrete waste use in the production of new concrete are pushing the Brazilian researches. However, despite significant advances ...
Performance estimation for concretes made with recycled aggregates of construction and demolition waste of some Brazilian cities
(ABM, ABC, ABPol, 2012)
The aim of this paper is to verify the influence of composition variability of recycled aggregates (RA) of construction and demolition wastes (CDW) on the performance of concretes. Performance was evaluated building ...
Influence of natural coarse aggregate type on the transport properties of recycled concrete
(American Society of Civil Engineers, 2014-06)
The use of recycled concrete represents a friendly environmental solution for minimizing the impact of construction and demolition wastes. In many countries, the incorporation of recycled coarse aggregates (RCA) is a common ...
Use of recycled fine aggregate in concretes with durable requirements
(Pergamon-Elsevier Science Ltd, 2011-11)
The use of construction waste materials as aggregates for concrete production is highly attractive compared to the use of non-renewable natural resources, promoting environmental protection and allowing the development of ...
