Recycling waste from natural stone processing plants to stabilise clayey soil

Abstract

For the countries with a developed stone industry the waste generated in the natural stone processing plants pose environmental and economic problems. The utilisation of stone waste in various areas is still under research. In addition, there are only a limited number of studies concerning the use of stone waste obtained from processing plants in the stabilisation of clayey soil. Furthermore, none of the studies in the literature investigated the effect of the characteristics of the stone on the stabilisation of the soil. This is the first study that compares the efficiency of the waste calcitic marble, dolomitic marble and granite powder as additives for the stabilisation of clayey soil. Artificial soil samples were prepared in the laboratory using bentonite and kaolinite. Natural stone waste powder was added to the soil samples at different percentages, and the index and compaction parameters of the stabilised soil were analysed. The results showed that the types of waste powder used in this study, like lime, could be used as stabilisers. As the percentage of additives increased, the plasticity index of the clayey soil decreased and the physical properties of the soil changed from clay to silt. In terms of compaction parameters, the use of all types of natural waste powder in the study resulted in a decrease in the optimum water content and an increase in the maximum dry unit weight. The lowest optimum water content and the highest maximum dry unit weight were obtained from the dolomitic marble powder.

Experimental Insights of Using Waste Marble Fines to Modify the Geotechnical Properties of a Lateritic Soil

“…The liquid limits and plasticity indices of the treated soil samples decreased with their WMF contents, in alignment with the results of Sivrikaya et al (2014) and Baser (2009) on expansive soils. Although Sivrikaya et al (2014) and Baser (2009) reported an increase in the plastic limits of the expansive soil with increasing marble dust, the plastic limits of the treated lateritic clay samples were not significantly affected by increasing their WMF contents.…”

“…Although the soil considered by Sivrikaya et al (2014) is not lateritic, the effect of adding marble dust to the expansive soil on its compaction characteristics is similar to that obtained for this study.…”

Granite Dust is the Possible Component of the Dry Construction Mixtures

“…For example, up to 25-30 % of screenings from crushing granite is produced during the manufacturing of coarse aggregate [1]. In addition, the granite dust (GD) with a grains size less than 0.16 mm is formed when screenings screening on narrow fractions in production process of graded sand as well as during working of dust collection systems of crushing and screening equipment.…”

Dye Removal From Textile Waste Water Through The Adsorption By Pumice Used In Stone Washing

“…[8,9]. These materials could also be used in the construction of housing, public buildings and roads and thus their consumption in this area is another solution for the waste adsorbents [8,10].…”
