“…In cement systems, glass waste ground very finely acted as a pozzolanic material and for that reason it is possible to substitute some amount of Portland cement with ground glass waste. By comparing two types of cementitious materials, such as ground glass waste and silica fume, mortar or concrete containing ground glass waste exhibited a similar or slightly lower compressive strength [ 15 , 16 , 17 , 18 , 19 ].…”

“…The highest compressive strength was detected in mixtures with a combination of silica fumes and ground glass powder or expanded glass [ 18 , 19 ]. In some cases, the values of compressive strength reached the values of high-strength concrete [ 19 ]. Vaitkevičius et al [ 20 ] determined that ground glass waste is similar to a contender for silica fumes, which had the positive development of compressive strength.…”

In the construction industry, the selection of sustainable materials leads to a movement towards more sustainable construction. In this study, lightweight aggregate shotcrete based on expanded glass (EG) and expanded clay (EC) is investigated. The goal of the study is to determine the influence of EG and EC inclusion on the properties of shotcrete. Ordinary Portland cement (OPC) powder with supplementary cementitious materials, such as silica fume and ground glass waste, are used as binders. The mechanical, physical and morphological properties, as well as the mineral and oxygen compositions, are obtained through compressive and flexural strength tests, thermal conductivity measurements, scanning electron microscopy with energy dispersive X-ray spectrometry (SEM–EDX), X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis. In this study, the mechanical, physical and thermal properties and waste utilization as cement supplementary materials are balanced. The shotcrete samples show that a density of 790 kg/m3 had a good thermal performance (thermal conductivity coefficient of 0.174 W/(m·K)) with the sufficient compressive strength of 6.26 MPa.

“…For each type of LWAC, different physical properties were tested as reference data for their potential practical applications. These tested properties include: strength (Cui et al, 2012a;Ilya et al, 2018;Medine et al, 2018), density (Lau et al, 2018), elasticity (Hilal et al, 2016), shrinkage (Alexandre Bogas et al, 2015;Rumšys et al, 2017), creep (Libre et al, 2011), thermal conductivity (Nguyen et al, 2017), abrasion resistance (Real and Bogas, 2017), and adsorption (Krc, 2015;Muñoz-Ruiperez et al, 2018). Although LWAC has its superiority in high strength and low density, LWAC has more obvious brittleness compared with other ordinary concretes, which can be partially attributed to its high strength (Beygi et al, 2014;Karamloo et al, 2016).…”

Factors Affecting Brittleness Behavior of Coal-Gangue Ceramsite Lightweight Aggregate Concrete

et al. 2020

Coal gangue, which is the solid waste produced during the coal processing, causes serious environmental problems. Lightweight concrete by making use of the coal-gangue ceramsite as the aggregate has many advantages as the construction material. However, the high brittleness of lightweight aggregate concrete is one of the problems for its application in building infrastructure. In this paper, the variation regularity, influencing factors and reinforcing/toughening method were studied as the reference data for future practical applications of coal-gangue ceramsite lightweight aggregate concrete (CGCLWAC). The results show that the brittleness of CGCLWAC increases with age, but the rate of the increase of brittleness keeps decreasing, and the brittleness is basically stable when the age beyond 28 days. When the sand ratio is above 0.38, the brittleness of CGCLWAC increases with the sand ratio; when the water cement ratio is above 0.32, the brittleness increases with the decrease of the water-cement ratio. Experiments show that when the content of steel fibers is less than 1.5%, the brittleness decreases with the increase of steel fiber content; when the content of steel fibers exceeds a critical value, the toughening effect decreases. From the macro-destructive morphology of the specimens, it is concluded that the incorporation of steel fibers can significantly change the brittleness of CGCLWAC. This study can serve to provide reference data for making use of the solid waste of the coal gangue and optimizing the infrastructure application scheme of CGCLWAC.
