Waste Glass Powder Reusability in High-Performance Concrete: Leaching Behavior and Ecotoxicity

Abstract

This paper deals with the possibility of using different types of waste glass powder in high-performance concrete (HPC) mixtures as a fine fraction replacement. Subsequently, both fractions are used in this research in concrete as a substitute for fine sand and silica flour. To use waste glass in a basic building material such as concrete, it is necessary to verify the basic chemical properties of the selected waste materials. Apart from the basic chemical properties, its environmental impact also appears to be an essential property of waste materials in general. Therefore, the research is mainly focused on the leaching and ecotoxicity experiments on high-performance concrete. HPC mixtures are designed based on the results of the analyzed chemical properties and previous research performed by our research team. Ecotoxicity of these concretes is then verified using Czech standards to evaluate. The results showed a positive impact on the ecotoxic properties of waste glass when used in concrete. A new ecotoxicity classification of waste materials and concrete mixes containing waste materials is proposed as a result of this research and summarized in the conclusion of this paper.

Alkali-silica Reaction Elimination Potential of High-Performance Concrete Containing Glass Powder

“…Leachates of both GP and HPC were prepared according to [ 27 ]. The chemical and ecotoxicological characterization procedure of leachates is described in [ 2 ].…”

“…This research deals with the threat of the alkali-silica reaction (ASR) in high-performance concrete (HPC) containing glass powder (GP) and directly follows on from the previous pilot research by the authors about the ASR [ 1 ] and a detailed study of the properties of HPC containing GP [ 2 , 3 , 4 , 5 ]. The authors are actively dealing with recycled aggregates, secondary raw materials, and waste materials during this extensive research in order to acquire sufficient knowledge in all interdisciplinary contexts [ 6 , 7 ].…”

“…WM or SRM utilization in concrete increases the need for thorough chemical analysis and overall toxic safety, especially in relation to nature. Ecotoxicological analysis elucidates interactions in biological systems and shows whether alternative concrete mixtures with glass substitutes can reduce the potential toxic effects of glass itself, as both glass and concrete are associated with toxicity that is related to heavy metal leaching or higher pH [ 2 ]. These facts often lead to problems with corrosion, dermatitis, or other reactions such as ASR [ 14 ].…”

Influence of Waste Glass Powder Addition on the Microstructure and Mechanical Properties of Autoclaved Building Materials

“…Waste glass deposited in landfills has been an issue for decades, as its recycling is often problematic due to the fact of chemical contamination or the presence of different coloring ions [1,2]. Over the last couple of years, numerous papers have been dedicated to the use of waste glass powder as a pozzolanic additive in traditional mortars and concretes (e.g., [1][2][3][4][5][6][7][8][9][10]). However, only a few describe the utilization of glass powder in the production of autoclaved building materials [11][12][13].…”

High‐performance concrete with fine recycled concrete aggregate: Experimental assessment

“…However, this composition leads to the use of high-quality natural resources such as which causes a high environmental footprint and costs. One of the possible ways to reduce the environmental footprint and cost of the HPC is replacement the powder or sand with secondary raw materials such as fine recycled aggregate (fRA), [6][7][8][9] glass powder, [10][11][12][13] limestone Discussion on this paper must be submitted within two months of the print publication. The discussion will then be published in print, along with the authors' closure, if any, approximately nine months after the print publication.…”
