This article presents the results of research on the possibility of replacing fly ash with recycled waste glass in lower-strength concrete mixes. The results of testing concrete mixes containing either waste-glass powder or fly ash are presented in the article. A standard C12/15 concrete mix was chosen for the tests based on its common use for producing concrete for footings to support road kerbs and gutters along national roads in the Polish province of West Pomerania. In the first step of the testing procedure, reference mixes were prepared with 22.5% and 45% fly ash in relation to the content of cement. In the next step, mixes were prepared based on the same specification, except that glass powder was added in place of fly ash. The samples were then tested to determine the influence of waste-glass powder on the main properties of the prepared concrete mixes and on the performance of the concrete when hardened. All the samples were tested for 7 and 28-day compressive strength, water absorption, and freeze-thaw resistance in water. Next, the performance parameters of the samples containing waste-glass powder were compared to the reference mixes containing an equal amount of fly ash. The test results and their analysis allow us to conclude that mixes containing glass powder are not only equal to mixes containing fly ash, but even outperform them by a wide margin in terms of durability.

Recycled Waste

As the concept of sustainable pavement gains prominence, a growing number of industrial wastes and recycled materials have been utilized in the pavement industry to preserve natural resources. This study investigates the potential use of waste glass powder-based geopolymer cement as a stabilizing agent in recycled waste glass aggregate (GA) bases. Two recycled materials, waste glass powder (GP) and class F fly ash (FF), were used as the raw materials in the preparation of geopolymer. Virgin aggregate (VA) was replaced by GA at varying replacement ratios as the pavement base materials, and the mechanical behaviors before and after geopolymer stabilization were evaluated. Without stabilization, the incorporation of over 10% GA caused significant detrimental effects on the California bearing ratios (CBR) of base materials, which should be carefully managed in pavement construction. However, all geopolymer stabilized samples showed decent strength properties, indicating the effectiveness of geopolymer stabilization. The use of GA reduced the drying shrinkage of base samples, although the mechanical properties were compromised. During the sample preparation, a higher curing temperature and relative humidity resulted in better mechanical behaviors, and the surface of GA could dissolve in alkaline solution and involve in the geopolymerization at 40°C. The microstructure and minerology of geopolymer stabilizer of base materials were characterized by scanning electron microscopy (SEM) and X-ray defraction (XRD) analyses. This study confirmed the promise of using waste glass-based pavement base materials as the greener substitutes and the potential synergy between waste glass recycling and the pavement industry.

The utilization of solid waste materials or industrial waste as partial substitution of cement is growing in construction industry all around world. Less cement consumption causes consequently reduction in CO2 emission into the atmosphere and reduction in energy consumption. This paper examines the possibility of using finely ground waste glass as a partial replacement for cement and as a sealing admixture. Glass powder used in the research was prepared from the glass waste obtained from a local recycling company. Glass cullet made of brown glass, which after rinsing to remove sugars and other impurities, was dried and ground to a fraction below 125 μm.This paper is the revised version of the paper that has been published in the Proceedings of the Creative Construction Conference 2018 (Horszczaruk and Brzozowski, 2018).
