۱٫ Introduction

Concrete is one of the most widely used construction materials, and it is a fundamental material in nearly all structures. Alternative aggregates are, however, very much needed because aggregate shortages abound due to the exhaustion of natural aggregates and strict environmental restrictions placed on the construction industry. In addition, with rapid industrial development as well as the improvement living standard, the amount of domestic and industrial waste is increasing. Treatment of such types of waste has become a serious issue, and a globally unified effort is needed to implement technologies for effective waste recycling and resource recirculation. Against this context, several types of industrial waste are currently being used in the manufacturing of eco-friendly materials, which can replace existing construction materials. Among the various types of industrial waste, glass is considered to be the most suitable substitute as an aggregate due to its physical characteristics and chemical composition [1–۳]. Furthermore, previous study has shown that recycled glass may be suitable for use in a wide range of applications, including concrete, bricks, and in highway engineering projects [4–۷]. In particular, since 2012, when analog TV broadcasting ended, and systems converted to digital TV broadcasting in South Korea, a large volume of cathode ray tube (CRT) TVs and monitors were discarded and replaced with LCD panels. The amount of electronic waste, including waste CRT glass from CRT TVs and monitors, increased from 910,000 ea. in 2012 to 970,000 ea., and is currently projected to increase to about 10 million ea. in 2020 [8,9]. Just as notable is that most of the old CRT TVs and monitors are not recycled despite the fact that parts, including the CRTs, can be. CRT glass products are classified into panels and funnels, wherein the panels may be reused as glass after washing, but the funnels, containing a large number of heavy metals such as iron and lead, are difficult to treat using conventional recycling technology. Heavyweight waste glass has therefore frequently been illegally dumped or buried in landfills, leading to serious environmental pollution [10]. As a result, it is important to find effective recycling methods for heavyweight waste glass that contains heavy metals. One possible option that has been studied includes applying waste glass as an alternative concrete aggregate [2,10–۲۱], however, studies specifically on the durability of concrete are lacking. Many of the existing studies involve mortar [11,14,21]. Most studies also used treated waste glass in the form of crushed glass in which heavy metals were removed [15–۱۹]. Such waste glass treatment process is very complicated. In South Korea, a study was conducted to investigate the applicability of heavyweight waste glass crushed solely by a jaw crusher [10,21]. In this paper, heavyweight waste glass was simply crushed by jaw crushers, and not all of the heavy metal in the waste glass was removed, making it a very simple process.
