“…In experiments conducted on bentonite, sand, Colemanite and ulexite mixtures with different contents, it was determined that the liquid limit value and optimum water content increased simultaneously as the Colemanite ratio increased [12]. It was concluded that by adding an equal percentage of Colemanite to high plasticity clays, the strength, swelling pressure and hydraulic conductivity values decreased.…”

The aim of this study is to provide an alternative solution to ground improvement methods by using natural additive Boron, and recycled Ceramics in order to increase the strength of fine-grained sands and determine their physical and mechanical behaviors and implement sustainable and naturebased rehabilitation methods. In the study, clean angular sand samples were used as a base material. As an additive, boron derivative Colemanite and shells of recycled Ceramics were used. Those additive materials were added to the base material at rates of 5%, 10% and 15% based on the dry weights. Afterwards, 6 new mixed soil types were produced for the examinations. Atterberg limits, void ratio, specific gravity, unit volume weight, compaction and permeability tests were carried out on these samples. Regarding the comparison of the test results, Colemanite and sand mixtures reduce the permeability and void ratio significantly compared to Ceramic and Sand mixtures while increasing the compactness. It has been determined that the mechanical performance of Ceramic mixture sands has positive trend compared to the reference sand which has no additive. It is recommended to use both additives in 15% combination with sandy soil to set optimum results. This paper represents the findings from the laboratory research with particular emphasis on the use of mentioned alternative materials that provide more strengthened soils which result in economic benefits as well as reduced environmental impacts.

“…Boron, the 51st element commonly found in the earth, is never found free and it is known that there are approximately 230 types of boron minerals [17]. Boric acid (H3BO3), which has many production methods, is a boron intermediate used in many industries [18].…”

Energy and exergy analysis of systems are of great importance to enhance the energy and exergy efficiency of industrial production facilities. With the energy and exergy analyses performed, the energy dependency of the production facilities and their energy consumption can be reduced, the price of the product can decrease, and the profit margin can increase. Additionally, it is ensured that the energy produced based on fossil fuels is used in a controlled way. In the present study, the analysis of energy and exergy has been performed for the production reactor unit of the Boric Acid from Colemanite. The first law of thermodynamics and ChemCAD simulation program was used for energy analysis calculations, and the calculations of exergy analysis were carried out by using the second law of thermodynamics. The total energy loss of the reactor unit and the calculated energy loss per 100 kcal input steam were calculated as 110880 kcal/h and 3.724%, and the losses of total exergy in the reactor units and the losses of exergy calculated per 100 kcal input steam were calculated as 225058.86 kcal/h and 30.095%, respectively. Exergy efficiency for the reactor unit has been determined as 3.3 %. Some suggestions were given for the reactor units of boric acid production plants to minimize system losses.

“…Bu nedenle çalışmada üleksitin konsolidasyon (oda sıcaklığında) ve kayma dayanımı (oda sıcaklığında ve 80°C'de) davranışı üzerindeki etkileri araştırılmıştır. Yazarların daha önce yayınlanan çalışmalarından (Alpaydın ve Yukselen-Aksoy, 2018a; Alpaydın ve Yukselen-Aksoy, 2018b) farklı olarak bu çalışmada karışım oranları farklı şekilde hazırlanmıştır [14,15]. Ayrıca yazarların yaptıkları çalışmadan (Alpaydın ve Yukselen-Aksoy, 2018b) farklı olarak bu çalışmada 90°C yerine 80°C sıcaklık altında deneyler yapılmış, ve kesme hızı iki kat arttırılarak deneyler gerçekleştirilmiştir [15].…”
