Use of marble dust and fly ash in stabilization of base material

Abstract

Marble dust and fly ash are waste materials and used in various area and industries as an additive material. However, there are still significant amounts of marble dust and fly ash left as waste. Therefore, the reuse of these wastes provides benefits to reduce construction costs and increase sustainability. In this study, a laboratory testing program was conducted on granular soil specimens amended with marble dust and fly ash. The specimens were prepared with granular soil and marble dust-fly ash at different mixing ratios. They were compacted with standard and modified Proctor energies. The specimens were subjected to unconfined compression, California bearing ratio, and freezing-thawing tests. The results of the study show that the strength of a specimen is dependent on the additive ratio, the curing period, compaction energy, and the number of freeze-thaw (F-T) cycles. Generally, unconfined compressive strength (q u ) and California bearing ratio (CBR) increased with additive materials, curing times, and high compaction energy. q u decreased and weight loss increased with increasing additives and increasing F-T cycles.

Usage of Fly Ash and Waste Slime Boron for Soil Stabilization

“…The reason for the increase in the optimum water content is an increase in the particle surface area of samples due to the addition of finer materials. Similar trends have been obtained from some experimental works [3,4,5,6,7].…”

“…For the sample preparation, the granular soil was mixed with waste slime boron and fly ash at three different ratios and the dry weights of the materials were used for the mixtures. The percentage of additives was obtained from literature [5,6,8]. All of the specimens were compacted with standard Proctor compaction energies and optimum water contents.…”

“…There are a lot of studies about fly ash used in the stabilization of soils. In the previous studies [2,3,4,5,6,7] it was indicated that the engineering properties of fly ash amended soils have been improved. Generally, fly ash was used together with different additive materials like cement, lime or industrial wastes like marble dust, cement kiln dust, etc.…”

The usability of industrial wastes on soil stabilization

“…There are a host of studies performed with FA for soil stabilization. In these works, FA was usually combined with different additive materials such as lime, cement, and industrial wastes (Arora et al, 2005;Cetin et al, 2010;Fauzi et al, 2011;Zorluer & Demirbas, 2013;Zorluer & Gucek, 2014, 2017a, 2017bVerma & Singh, 2017;Yoobanpot et al, 2017;James & Pandian, 2018).…”

“…More than 90% of MD has a grain size smaller than 0.2 mm. Marble dust has been examined as a soil stabilizer in many earlier studies (e.g., Fırat et al, 2012;Zorluer & Demirbas, 2013;Zorluer & Gucek, 2014;Gurbuz, 2015;Kesvehan et al, 2017;Verma & Singh, 2017).…”
