Utilization of Industrial Wastes for Improving Geotechnical Properties of Collapsible Soil

Abstract

At the present time the disposal of industrial wastes has become a challenge for most countries. This research aims to study the effect of mixing the industrial textile sludge on geotechnical properties of collapsible soil. The experimental program studies the effect of textile wastes on Atterberg limits, collapse potential, compaction, CBR, and shear strength parameters. The percentages of textile wastes mixed with soil are 4, 8, 12, 16, 20, and 24 %. The results indicated that the collapse potential of untreated soil is significantly decreased from about 11% to 2.6% at 24% of textile sludge. Shear test results show an increase in cohesion and decrease in the internal friction angle. For Atterberg limits there was an increase in liquid limit. For Compaction results, it is noticed a decrease in maximum dry density and an increase in optimum moisture content. CBR values for all samples indicates the suitability of using soil and soil-sludge mixtures only in subgrade layer of pavement. It was found that the reuse of textile sludge with collapsible soils considers an economic method to improve the physical and mechanical properties of the soil, in addition, it could be considered as sustainable management of textile sludge which leads to a reduction in the consumption of natural resources and preserves the surrounding environment through decreasing the retention of these wastes to a minimum.

Spectroscopic study of collapsing soil microstructure to explore the physical properties afterward incorporating textile wastes

“…Collapse potential was significantly decreased by adding 24 percent textile sludge to collapsible soil, reaching a value of 76.36%, as revealed by the decline in volumetric strain at 200 KN/m2 in Fig. 3 (Abbas et al, 2021). for dry samples.…”

“…The goal of this study is to finish our prior work on Abbas et al (2021) from a different angle. The authors of the published study want to identify a long-lasting and low-cost addition to enhance the mechanical qualities of collapsing soil.…”

“…According to Abbas et al (2021), the soil used in this study comes from the Borg el-Arab region in northern Egypt, which is roughly 62 kilometres west of Alexandria. As indicated in Fig.…”

“…According to Abbas et al (2021), The textile sludge (T.S) was taken from a textile Plant in Tanta, Egypt. As illustrated by Fig.…”

“…According to Fig. 5, when textile sludge was added to soil at a rate of 24%, the liquid limit value of the collapsing soil increased from 30% to 41% (Abbas et al, 2021).…”
