    Water Scarcity and the Construction Industry: Implementation of Alternative Sources of Drinking Water for Civil Works
    (2023-12-19) Bonell, Valentina; Canova, Eliana Evelyn
    Abstract— This article focuses on the importance of using potable water, a limited and essential resource, in the production of concrete in the construction industry. It is also highlighted that the use of non-potable water in the production of concrete is inefficient. Additionally, it explores various innovative solutions to obtain drinking water that does not depend on conventional water sources. These solutions include desalination, transforming wastewater into drinking water, rainwater harvesting, and modifying concrete mixes to make them less sensitive to the type of water used. It is expected that this work can generate a significant impact on readers and encourage the adoption and promotion or alternative ways of generating safe water for civil works.

    Low-Carbon 3D Printed Concrete: A General Review of the Technology and Method
    (2023-11-28) Soutus, Joaquin
    Abstract— During the last decades, there has been an increase in interest in news about technologies and application methods to turn concrete into a less polluting material. 3-D Printed Concrete technology is an innovation in this direction. The main purpose of this paper is to address the pollution issue in construction in general and in the concrete industry in particular. To achieve this aim, this paper is divided into three sections. The first section, the construction industry and concrete contamination is explained. The second section introduces 3D Printed Concrete technologies as a possible solution to the contamination issue, describing its composition, properties and elaboration process. Finally, the last section delves into the main economic, technological and environmental benefits of this technology. It is expected that this work can motivate the incorporation of new building technologies in the construction industry to address the contamination issue and contribute to environmental improvement.
