Multicriteria analysis of the environmental and economic performance of circularity strategies for concrete waste recycling in Spain
(2022-05-01)
Article
Open AccessConstruction and demolition waste (CDW) is identified by multiple circular economy (CE) policies as a key sector for implementing circularity strategies due to the high volume of waste produced and the large consumption ... -
Non-destructive screening methodology based on handheld XRF for the classification of concrete: cement type-driven separation

Optimization and dust emissions analysis of the air jigging technology applied to the recycling of construction and demolition waste
(2020-07-15)
Article
Open AccessThis work aims to evaluate the use of the air jigging technique, a density-based separation technology commonly applied in mineral processing, to upgrade the quality of mixtures (density and geometric properties) that ... -
Properties of plain concrete produced employing recycled aggregates and sea water
(Springer, 2018-09)
Article
Open AccessThe generation of construction and demolition waste (C&DW) is a noteworthy environmental and economic concern. The development of new applications in which Recycled Mixed Aggregates (RMA) can be used will lead to a reduction ... -
Propiedades físicas y mecánicas de los agregados reciclados de concreto
(Instituto Mexicano del Cemento y el Concreto, 2002)
Article
Open AccessLas propiedades a largo plazo, como la contracción y fluencia, de los concretos reciclados(CR) presentan algunas variaciones con los concretos usuales. Dichas variaciones son interpretadas por las diferencias de densidad, ... -

Reactivity of binary construction and demolition waste mix as supplementary cementitious materials
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-11)
Article
Open AccessCalcareous and siliceous CDW wastes from concrete and glass wastes when mixed in binary mixtures has been analyzed in this study. Fine CDW fractions (<5 mm) of different sorts are selected: siliceous waste (HsT), calcareous ... -
Recovery of demolished house rocks from construction and demolition waste with water jigs
(2023-12-29)
Article
Open AccessThe European Union (EU) is responsible for generating quantities ranging from 310 to almost 700 million tons of construction and demolition waste (CDW) per year. Consisting of over 70% inert material (concrete, ceramics, ... -
Relationship between gas adsorption and the shrinkage and creep of recycled aggregate concrete
(2003)
Article
Open AccessIn this work, it is described an experimental analysis of specimens of recycled concrete (RC) with replacement of natural aggregate with recycled aggregate originating from concrete (RCA). An experimental analysis to obtain ... -
Repercussions on concrete permeability due to recycled concrete aggregate
(V.M. Malhotra, 2001)
Conference lecture
Open AccessThis paper presents an experimental analysis of recycled concrete (RC) in which the natural aggregates are replaced by recycled concrete aggregates (RCA). This experimental program covers the specifications of the aggregates ... -
Review of waste concrete recycling and application
(Universitat Politècnica de Catalunya / Zhejiang University, 2011)
Master thesis (pre-Bologna period)
Restricted access - author's decisionAlong this review, an introduction to the concrete world recycling will be done. Concrete is almost in every building or road that is around us. As the world changes, new buildings and runways are needed, therefore waste ... -
Self-sensing concrete made from recycled carbon fibres
(2019-10)
Article
Open AccessThe electrical and piezo-resistive responses of recycled carbon fibre (rCF)-reinforced concrete is analysed in this article. Two different PAN-based rCFs (monofilament rCF and fibrillated rCF sheets) incorporated into dry ... -
