“…In the case of a glass cullet, it can be recycled entirely to exploit alternatives to its final disposal. They could be used as additives in asphalt and concrete production [31,32]. As a technical alternative, the author's research works have glass cullet used in obtaining glass-ceramics, bearing in mind that these materials may have attractive properties for applications in several industrial sectors.…”

The paper presents research on multicomponent glasses obtained from natural and secondary raw materials, i.e., basalt, amphibolite, and cullet. The raw materials were used as potential sets to produce mineral fibres or glass-ceramic materials. FTIR spectroscopy and XRD studies were carried out to identify the composition of the phase type in the glass sets. The results were supported by SEM-EDS microstructural studies of the obtained materials. The ability of the melts to crystallize and their basic properties required in producing mineral fibres, i.e., the hardness and the acidity modulus, were also determined. In the glass samples after the crystallization process, the spectroscopic studies revealed an increase in the half-width of the band at 1200–800 cm−1 and splitting at the values of about 870 cm−1 and 970 cm−1. These changes probably indicate the formation of pyroxene-type crystalline phases. Moreover, based on the XRD results, it was confirmed that the obtained materials were fully amorphous. After annealing at 800 °C for 2 h, the materials show a small proportion of crystalline phases. For the materials annealed at higher temperatures, clear peaks from the crystalline phases were represented mainly by pyroxenes. The proportion of crystalline phases in the samples was also found to rise with increasing temperature, and the hardness values for the basalt glasses and glasses after crystallization rose from 753 to 946 HV0.05. Such an effect positively affects the properties of the obtained glass-ceramic materials based on the proposed sets. However, in the case of mineral fibres, crystallization at early 2 h at 800 °C can be a disadvantageous feature from the point of view of their application because crystalline phases can lead to fibre damage after a short period of operation; this will be confirmed in this study.

“…In the case of glass cullet, approximately 5000 tons per year are derived from consumption and production processes in the Boyacá region: This residue can be completely recycled in order to exploit alternatives to its final disposal. It is evident, in accordance with the amount of waste generated in Boyacá, that these residues could be used as additives in the production of asphalt and concrete [9,10]. As a technical alternative, research has focused on the use of such residues in obtaining glass-ceramics, bearing in mind that these materials may have attractive properties for applications in several industrial sectors.…”

Developments in the field of materials science are contributing to providing solutions for the recycling of industrial residues to develop new materials. Such approaches generate new products and provide optimal alternatives to the final disposal of different types of industrial wastes. This research focused on identifying and characterizing slag, fly ash, and glass cullet from the Boyacá region in Colombia as raw materials for producing glass-ceramics, with the innovative aspect of the use of these three residues without the addition of nucleating agents to produce the glass-ceramics. To characterize the starting materials, X-ray diffraction (XRD), X-ray fluorescence (XRF), and Scanning Electron Microscopy (SEM) techniques were used. The results were used to evaluate the best conditions to produce mixtures of the three waste components and to determine the specific compositions of glass-ceramics to achieve products with attractive technical properties for potential industrial applications. The proposed mixtures were based on three compositions: Mixture 1, 2, and 3. The materials were obtained through thermal treatment at 1200 °C in a tubular furnace in accordance with the results of a comprehensive characterization using thermal analysis. The microstructure, thermal stability, and structural characteristics of the samples were examined through SEM, differential thermal analysis (DTA), and XRD analyses, which showed that the main crystalline phases were diopside and anorthite, with a small amount of enstatite and gehlenite. The obtained glass-ceramics showed properties of technical significance for structural applications.

<p>El cemento es una de las materias primas en la producción del concreto hidráulico, pero su producción es considerada como uno de los procesos más contaminantes en nuestro planeta. El proyecto de investigación analiza el comportamiento mecánico, físico y químico de una mezcla de concreto hidráulico modificado con sílice obtenida por la incineración de cascarilla de arroz. La metodología utilizada fue un diseño experimental que se trabajó con cemento Holcim M1 Concretera, se utilizó como muestra patrón un diseño de mezcla de concreto hidráulico para una resistencia a la compresión de 350 Kg/cm2, y resistencia a la flexión de 42 Kg/cm2. La modificación se realizó mediante la sustitución del cemento por ceniza de cascarilla de arroz (sílice), en proporciones del 5%, 15% y 30%. Los resultados muestran la viabilidad para el porcentaje de sustitución de 5% en la resistencia a la compresión, la tracción indirecta y a la flexión, por lo tanto, hay una viabilidad técnica para aplicar este procedimiento.</p>
