A concurrent multiscale approach for modeling recycled aggregate concrete
(2021-01-18)
The use of recycled concrete aggregates in new concrete is an alternative that can provide economical and environmental benefits. However, the influence of the inert particles on the mechanical behavior of concrete needs ...
A critical review of the resulting effective water-to-cement ratio of fine recycled aggregate concrete
(Elsevier, 2021-12-27)
The initial moisture condition of recycled concrete aggregates has a great influence on the fresh and hardened state of concrete. Water compensation is generally proposed with the aim of avoiding changes in the effective ...
Recycled aggregate concrete: Localized failure assessment in thermodynamically consistent non-local plasticity framework
(Pergamon-Elsevier Science Ltd, 2017-01)
A gradient plasticity theory is extended to predict the mechanical failure behavior of concrete with recycled aggregates. A relevant feature of the novel constitutive formulation is its full consistency with the thermodynamic ...
Understanding the influence of properties of fine recycled aggregates on recycled concrete
(ICE Publishing, 2020-12-07)
Scarcity of fine natural aggregates suitable for concrete, the pollution caused by their mining and the great environmental impact produced by the final disposal of waste concrete, have all motivated several studies about ...
Influence of Waste Brick Powder in the Mechanical Properties of Recycled Aggregate Concrete
Brick and concrete are the main materials contributing to demolition and construction waste. Considering this precedent, the effects of using both residuals in medium strength concretes are analyzed. Waste brick powder is ...
Structural contribution of the fine particles present in the mastic of aggregates used to make recycled bases with foamed asphalt and asphalt emulsion
(Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
The use of foamed asphalt as a technique that incorporates recycled bases stabilized with RAP is known, because it achieves important structural contributions. However, the component of aggregates, belonging to the fine ...
Recycled Concretes Made with Waste Ready-Mix Concrete as Coarse Aggregate
(American Society of Civil Engineers, 2011-03)
Using waste materials for new products is a global trend undergoing rapid development. Recycling materials allows for a more efficient life cycle and contributes to environmental protection. In the construction field, this ...
Incorporation of recycled aggregates from construction and demolition waste in paver blocks
(IBRACON - Instituto Brasileiro do Concreto, 2020-08-24)
Estudo da influência do teor de finos dos agregados reciclados mistos nas propriedades das argamassas de revestimento
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2016-07-14)
The expansion of the construction is of great importance for the economic development of the
country, due to the prominent position the sector takes in economy, creating jobs, enabling
housing, income and infrastructure. ...
External sulphate attack on recycled concrete: Assessment of the influence of recycled aggregate
(Springer, 2020)
The performance of recycled aggregate concrete (RAC) under external sulfate attack (ESA) has not been fully clarified yet. The attached mortar on recycled aggregate particles increases the content of hydration products ...
