Waste glass in civil engineering applications—A review

Abstract

Each year, hundreds of thousands of tons of industrial wastes are being stockpiled, landfilled, and disposed of in storages occupying large areas of land that would otherwise be available for productive use. Recycling of such wastes is now becoming of urgent global interest due to an increasing population, the rise in anthropogenic activities, and the need for more efficient resource and waste management systems.Among many wastes, the generation of glass is dramatically increasing, particularly in the municipal, industrial, and construction sectors. In civil engineering, in general, crushed waste glass has been mainly investigated as a substitute for sand and finegrained aggregate in concrete production. In geotechnical engineering, in particular, the application of glass wastes is mainly limited to road pavements or as an additive to different soils for subgrade improvement. While glass wastes are relatively inert and potentially offer several opportunities for recycling as a substitute for diminishing and increasingly expensive sand supplies, their potential use yet remains relatively under-researched. This paper systematically reviews the current status of knowledge on the use of glass wastes in various civil engineering applications and discusses the suitability assessment of waste glass for use as a sustainable alternative to traditional civil engineering materials.

Waste Glass in Cement and Geopolymer Concretes: A Review on Durability and Challenges

“…There are some review studies on WG incorporated concrete [ 28 , 29 , 30 ], but most of those are focused on the mechanical properties of cement-based concrete. In those published review papers, the effect of particle size and amount of glass on the physical and mechanical properties of WG concrete are described.…”

Diffusion and Containment Factors of Innovative Technology for Obtaining Building Materials From Phosphogypsum in the Industry

“…Отчасти, эту проблему решает переработка различных отходов в строительные материалы. Перерабатывают всё: ТБО, отходы промышленности, остатки вышедших из эксплуатации и, как следствие, разрушенных зданий и сооружений [20][21][22]. Этой теме посвящено множество научных статей и трудов [23][24][25].…”

The potential use of crushed waste glass as a sustainable alternative to natural and manufactured sand in geotechnical applications

“…One of the ways of reducing the consumption of natural sand is to utilise wastes as an alternative material (Emery, 1974). Recycling of wastes could reduce the demand for virgin natural resources and help to dispose of them effectively (Kazmi et al, 2019b). The volumes of wastes generated each year are alarmingly increasing due to a rise in the global population.…”

“…Chen et al (2020) explored the fire resistance performance of cementitious composites containing CWG. Several studies have shown that CWG may be partially used as supplementary cementitious material and alternative to fine-grained aggregates in concrete production (Kazmi et al, 2019b). These applications, among others, typically utilise only some of the CWG produced (generally less than 40%).…”

“…including its low ability to hold and absorb water, substantial changes in gradation curves pre and post-compaction, and relatively higher segregation potential. It was concluded that CWG with coarse particles reduces its potential for use in geotechnical engineering applications.However, the same study reported that CWG with fine and medium-sized particles offered superior geotechnical behaviour, comparable to traditional sand, and could potentially be used in a range of geotechnical applications.Currently, the use of CWG in traditional geotechnical applications is relatively underresearched(Kazmi et al, 2019b). Secondly, there are presently limited suppliers of CWG in Australia offering CWG for recycling applications.…”
