Soils are made stronger and more durable by mixing additive materials. In particular, the use of waste provides environmental and economic advantages for this case. Wastes form in large quantities, however, which creates storage problems. To objective of this study is to research the availability of industrial wastes for soil stabilization. An experimental study was conducted on granular soil specimens mixed with industrial wastes such as marble and granite dust, boron waste, and fly ash in different ratios. Each mixture used two waste materials together. Specifically, fly ash was used with three additional waste materials because of its pozzolanic characteristics. The tests performed included freezing-thawing, unconfined compression strength, and California bearing ratio. The results of the study show that the strength of a specimen is dependent on the additive ratio, curing period, and the number of freeze-thaw cycles. Generally, unconfined compressive strength and California bearing ratio increased with additive materials and curing times. After freezing and thawing, unconfined compressive strength (except granite dust) decreased, whereas weight loss increased due to increasing additives and increasing freeze-thaw cycles.
The use of waste materials as an additive in soil stabilization has been widespread. This is important in terms of recycling of waste materials and reducing environmental pollution. The objective of this study is to investigate the beneficial reuse of marble dust and fly ash in soil stabilization. Tests were performed on clay soil mixtures amended with marble dust and fly ash. Marble dust was used as an activator due to fly ash being inadequate for self-cementing. Unconfined compressive strength (qu), freeze-thaw, swelling, and California bearing ratio (CBR) tests were conducted to investigate the effect of marble dust and fly ash, curing time, and molding water content on geotechnical parameters. Addition of marble dust and fly ash increased unconfined compressive strength, CBR, and freeze-thaw strength, but these additives decreased swelling potential and grain loss after freeze-thaw. Increasing the curing time results in increased strength of mixtures and decreased grain loss. As a result, this study shows that the geotechnical properties of clay soil are improved with the addition of marble dust and fly ash. This is an economical and environmentally friendly solution.
In this study, the ratio of compaction was determined by sand cone and nuclear test methods performed in the same place. The normal distribution fitness of the compaction percentiles was tested by the Anderson-Darling test and normal distribution was normalized by subjecting the unsuitable Water Content values to Jonson transformation. Findings the results obtained with the nuclear method reveal that both methods are consistent with each other in terms of mean data, with lower and more variables in the Sand Cone method. It is recommended to test the consistency of the results obtained by the nuclear method. Also, because of the rapid results, statistical model has been investigated for adapting the results of nuclear method to the sand cone method. For this purpose, regression analysis and artificial neural network models were investigated; artificial neural networks were seen to provide successful predictions inside of the found models.
Bu çalışma, Afyonkarahisar il merkezinde 9 mahalleyi kapsayan Uydukent bölgesinin olası bir deprem etkisinde, yerleşim alanı içerisindeki alüvyal zeminlerin sıvılaşma potansiyelinin, arazi (SPT) verileri kullanılarak belirlenmesini içermektedir. Bu amaçla 70 noktada yapılan SPT verileri kullanılmıştır. Akşehir-Gediz Fay Sistemi, bölgeyi etkileyebileceği ve en büyük ivmeyi yaratabileceği varsayılarak araştırmaya esas alınmıştır. Güncellenen 2019 deprem haritası üzerinden 0,4g büyüklüğünde yatay deprem ivmesi oluşabileceği hesaplanmış, Mw=5.0, 6.0, 7.0 olan senaryo deprem büyüklüklerinde SPT verileri kullanılarak sıvılaşma analizleri yapılmıştır. Analiz sonuçlarına göre çalışma sahasını temsilen, bölge genelinde orta ve yüksek dereceli sıvılaşma riski olasılıkları belirlenmiş ve buna göre sıvılaşma risk haritası ortaya konulmuştur.
