“…It has been observed that the use of ash extracts or pulverized mass from the waste materials can alter the mineralogy and improve the index and engineering properties of a wide range of problematic soils (Sharma and Sivapullaiah 2017;Farah and Nalbantoglu 2019;Liang et al 2020). Therefore, the use of readily available, low-cost waste materials offers significant economic potential for improving the engineering properties of expansive soils (Ramaji 2012;Maneli et al 2016;Phetchuay et al 2016;Yang et al 2018;Aamir et al 2019;Chen et al 2021;Abdelkader et al 2022;Yarbaşı et al 2023).…”

<p>The use of appropriate waste materials to stabilize problematic soils, such as expansive soils that are responsible for geotechnical damage, is a common practice in geotechnical engineering. This study presents the use of pulverized ash from the combustion of pine cone (PC) waste as a stabilizing agent to improve the engineering properties of expansive soils. A series of laboratory tests were carried out to examine the effect of different percentages of pine cone ash (PCA) content (3%, 5%, 7%, and 10%) on the Atterberg limits, swelling potential (Sp), linear shrinkage, compressibility, and unconfined compressive strength (qu) of naturally occurring swelling soils and the PC ash-treated soils. The results showed that PC ash contents of 5% and 7% contributed to a significant reduction in the swelling and shrinkage potential and an improvement in the coarsest texture, brittleness behavior, compaction properties, and compressive strength of the treated soils. Conversely, PC ash contents below 3% and above 7% showed minimal changes in the index and engineering properties of the PC ash-treated soils. In particular, the PC ash content of 5% resulted in optimal mitigation of the poor properties of the treated soils. The use of pine cone ash as a stabilizing agent represents a suitable and complementary subgrade soil material for expansive soils on which lightweight structures are built.</p>

The use of natural resources and waste products represents an effective way of addressing a pressing concern for the future of the global population. It is therefore crucial to evaluate wastes and natural materials as raw materials in many industries. The present study sought to investigate the radiation protection features and experimental characteristics of tincal waste added with obsidians from Eastern Turkey (Nemrut, Pasinler, Sarıkamış and Ikizdere regions). Fourier transform infrared spectrometry, X-ray diffraction, Scanning electron microscopy and Energy dispersive spectroscopy were used to have knowledge for morphological and structural properties of the samples. The X-ray diffraction analysis of the samples with higher obsidian content revealed an amorphous structure with a minor presence of crystalline phases. In contrast, the samples with a higher tincal waste content exhibited crystalline phases. Based on morphologic results, it can be said that obsidian samples exhibited relatively smooth and glassy surfaces, whereas tincal waste displayed a rough surface comprising randomly shaped small particles. In addition, radiation attenuating abilities of the tincal waste added with obsidians were determined by the calculation of tenth value layers, half value layers, mean free paths, mass attenuation coefficients, linear attenuation coefficients, fast neutron removal cross sections, effective atomic numbers and buildup factors using the newly produced Phy-X/PSD code. It is obtained that the samples show good radiation protection performances and the samples can be evaluated as better radiation shields for radiation applications especially in construction industry.
