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 ...
Análise estatística da resistência à compressão e módulo de elasticidade de concretos com agregados de resíduos
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Civil - ECiv, 2021-04-23)
Civil construction is an important indicator of a country's economic and social development, but it is also an activity that generates environmental impacts and its residues have been a major problem for society. Part of ...
Influence of the moisture content on the dynamic modulus of elasticity of concrete made with recycled aggregate
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2019)
Constitutive Formulations for Concrete with Recycled Aggregates
(Springer, 2017)
In this Chapter, a thermodynamically consistent gradient model is proposedfor natural aggregate concrete and then, modified to take into account theaddition of different contents of recycled aggregates and its influence ...
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 ...
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 ...
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 ...
