Wastes as Aggregates, Binders or Additions in Mortars: Selecting Their Role Based on Characterization
(MDPI, 2018)
The production of waste has increased over the years and, lacking a recycle or recovery
solution, it is forwarded to landfill. The incorporation of wastes in cement-based materials is a solution
to reduce waste deposition. ...
Promotion of Circular Economy: Steelwork Dusts as Secondary Raw Material in Conventional Mortars
(MDPI, 2018)
Among the actions proposed by the European Union for the implementation of Circular Economy
is the use of waste as a secondary raw material (SRM). During the fusion of the scrap, a steel dust is generated,
named Electric ...
Catalogue of Pavements with Recycled Aggregates from Construction and Demolition Waste
(MDPI, 2018)
Construction and Demolition Waste come from debris generated during construction, renovation and demolition of buildings, roads, and bridges. Recycling and reuse are essential in terms of sustainability, mainly from an ...
A Novel Artificial Neural Network to Predict Compressive Strength of Recycled Aggregate Concrete
(MDPI, 2021)
Most regulations only allow the use of the coarse fraction of recycled concrete aggregate (RCA) for the manufacture of new concrete, although the heterogeneity of RCA makes it difficult to predict the compressive strength ...
Geopolymer concrete with treated recycled aggregates: Macro and microstructural behavior
(Elsevier, 2021)
Geopolymer concrete is a more environmentally friendly alternative than conventional concrete because its production does not need cement. Instead, waste materials such as fly ash, rice husk ash, slag, etc. are used. This ...
Effect of the Composition of Mixed Recycled Aggregates on Physical–Mechanical Properties
(MDPI, 2021)
Recycled aggregates (RA) from construction and demolition waste are an alternative to natural aggregates in the construction sector. They are usually classified according to their composition. The main constituent materials ...
Optimisation of mortar with Mg-Al-Hydrotalcite as sustainable management strategy lead waste
(MDPI, 2021)
This study analyses how a Mg-Al-Hydrotalcite with carbonate in the interlayer influences the hydration of mortar allowing the management of lead waste (solid or liquid) in a cement-based material. First, the compatibility ...
Preliminary Study of Recycled Aggregate Mortar for Electric Arc Furnace Dust Encapsulation
(MDPI, 2021)
This article shows the preliminary results of a study carried out to determine the technical feasibility of encapsulating a high percentage of EAFD in cement-based mortars manufactured with the fine fraction of recycled ...
The Performance of Concrete Made with Secondary Products—Recycled Coarse Aggregates, Recycled Cement Mortar, and Fly Ash–Slag Mix
(MDPI, 2022)
The properties of cement concrete using waste materials—namely, recycled cement mortar, fly ash–slag, and recycled concrete aggregate—are presented. A treatment process for waste materials is proposed. Two research experiments ...
Performance of Sustainable Mortars Made with Filler from Different Construction By-Products
(MDPI, 2022)
One way to contribute to sustainability in the construction sector is through the incorporation of construction by-products from their own activities. This work intends to extend the possibilities for enhancement of these ...
