“…Many works have proposed fine-ground glass instead of Portland cement [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ] or geopolymer cement [ 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 ]. However, in the literature, there is a lack of knowledge concerning the influence of fine-ground glass on the properties of alumina cement.…”

This paper discusses studies regarding the impact of fine-ground glass additives on the hydration and properties of alumina cement pastes and mortars. Fine-ground glass was added to pastes and mortars instead of high-alumina cement and calcium aluminate cement in quantities of 5% and 10%. The findings are inconclusive as to the impact of glass on the properties of tested alumina cement types. The effect produced via the addition of glass instead of cement depends on the type of alumina cement used. Adding fine-ground glass to high-alumina cement enhances the paste’s density while improving paste and mortar strength. Using the same additive for calcium aluminate cement reduces its density and strength. The addition of glass to high-alumina cement adversely affects its strength at higher temperatures.

“…Incorporating glass particles as aggregates causes the alkali-silica reaction (ASR) to occur (Cota et al 2015;Du and Tan 2013;Xie et al 2003;Rajabipour et al 2010;Lee et al 2011;Idir et al 2010a;Yamada and Ishiyama 2005), while fine glass powder is helps to mitigate ASR (Bažant et al 2000;Shi et al 2005;Kim et al 2014Kim et al , 2015You et al 2016;Zheng 2016;You et al 2019;Kalakada et al 2020) and increases resistance to chloride penetration (Kalakada et al 2020;Chen et al 2006;Shayan and Xu 2006;Tan and Du 2013;Guo et al 2015;Kou and Poon 2009;Lee et al 2018;Zidol et al 2017;Wang et al 2009;Jain et al 2020). Most of the recent research is focused on the use of glass powder as a partial substitute for cement binder for various purposes (Jain et al 2020;Kalakada et al 2020;Duan et al 2020;Mohammadyan-Yasouj and Ghaderi 2020;Shoaei et al 2020;Rodier et al 2020;Kadik et al 2020;Adesina and Das 2020;Bostanci 2020). Although the use of glass in a powdered form is beneficial from the mechanical point of view, powdering the glass consumes a significant amount of energy, which increases the cost.…”

A Novel Method of Crushing Glass Aggregates to Reduce the Alkali-Silica Reaction

This study proposed a novel method of crushing glass aggregates to reduce the alkali-silica reaction (ASR). Glass aggregates were crushed while immersed in different calcium bearing solutions. ASR measurement and compressive strength tests of mortars incorporating the glass aggregate were performed to investigate the feasibility of the crushing method. The results indicate that the crushing method was effective in both ASR mitigation and compressive strength improvement. Calcium nitrite solution was found to be more effective than calcium chloride solution for mitigating ASR damage. The ASR expansion after 14 days, measured in accordance with ASTM C1260, was 0.228% when the glass aggregates were conventionally crushed in air, which is potentially unsafe. This value decreased to 0.082% when the aggregates were crushed in calcium nitrite solution, a value which is considered innocuous. The compressive strength of the mortar was enhanced by approximately 12% compared to that of a mortar with conventionally crushed glass aggregate by incorporating glass aggregates crushed in calcium nitrite solution.

“…ese environmental problems have become more prominent with societal development, and more attention has been paid to alkali-activated slag and alkali-activated slag concrete (AASC) as new green gel materials [3,4]. e alkali-activated slag gel material consumes less energy and emits less carbon dioxide than cement in terms of production [5][6][7][8]. Furthermore, the alkali-activated slag gel material provides a feasible approach toward recycling industrial solid waste because slag is an industrial by-product, and the annual output has increased with continuous industrial development [9,10].…”

A freeze-thaw resistance is an important indicator of the durability of alkali-activated slag concrete, which causes structural failure when the performance is low, especially in severely cold areas. In this study, solid sodium aluminate and sodium silicate were used as composite alkaline activators, while slag was used as the raw material to prepare alkali-activated slag concrete, whose freeze-thaw resistance, as well as that of ordinary cement concrete, was experimentally studied by varying the freeze-thaw cycles. The effects of the mass, compressive strength, and dynamic elastic modulus of the sample were investigated by considering the influence of different water-to-slag ratios and slag contents, while the damage variables and model were also analyzed. The results showed that alkali-activated slag concrete had an excellent freeze-thaw resistance, which was significantly affected by the water-to-slag ratio and compressive strength; specifically, the higher the water-to-slag ratio, the lower the freeze-thaw resistance, and the higher the compressive strength, the better the freeze-thaw resistance. The freeze-thaw durability, microstructure, and damage mechanism were studied via microscopic analysis. When analyzed via the microstructure test, crack pores and microcracks with narrow spaces and large surface areas were generated under freeze-thaw damage conditions, but the dense hydration structure and high-bonding-strength hydration products led to a better freeze-thaw resistance. The damage model was established using compressive strength and relative dynamic elastic modulus as damage variables, and the attenuation exponential and accumulative damage power function model had a high accuracy, which could better reflect the freeze-thaw damage law and damage degree and predict the lifetime of alkali-activated slag concrete.
