stabilization is necessary. Clay soil is expansive soil and tends to expand on absorbing water and shrinks as water is drawn away. The current research article focuses on examining the strength behaviour of clayey soil utilizing industrial waste products like calcium-carbide-residue (CCR) and fly ash (FA). By maintaining an optimal ratio of CCR and FA in soil, soil properties can be enhanced. Therefore, the individual and combined effects of different proportions of CCR and FA are evaluated to compare the improvement of soil properties. Several tests such as the Atterberg limit test, Unconfined compressive strength (UCS) test and Compaction test are performed to determine the effectiveness of CCR and FA.
2. REVIEW OF LITERATURE Ayodele F. et al. (2022) have tried to find out the influence of binary blends of Rice Husk Ash (RHA) and Calcium Carbide Residue (CCR) on lateritic soil engineering properties. A noticeable improvement in soil consistency was noted. At different dosages of optimum CCR: RHA, the California Bearing Ratio improved for soil strength up to 6%. Overall, the stabilized soil strength as measured by UCS improved as additives were added. These additives improve the soil's ability to resist erosion. As the additive content of the soil increased, its plasticity decreased.
Key Words: Soil stabilization, Calcium-carbide-residue, Fly ash, engineering properties.
Latifi N. et al. (2018) have focused their study to examine CCR practicability to stabilize clay. Natural pozzolanic materials in clay can react with CCR following pozzolanic reactions. Tests indicated that a significant improvement in compressibility and strength has been observed utilizing CCR. The highest strength improvements in UCS tests were obtained with CCR dosages of 9% and 12% for bentonite and kaolin, respectively. After 28 and 90 days of curing, the UCS of the 9% added CCR tested bentonite increased by 4.7 and 6.8 times those of untreated soil respectively. Upon curing CCR-stabilized kaolin for 28 and 90 days, the UCS improved by 3.8 and 5.8 times, respectively.
1. INTRODUCTION The stabilization of soil is the process of improving the physical properties and strength of the soil so that it can be used over the long run. A soil's engineering properties like moisture content, shear strength, or other engineering properties are sometimes controlled chemically to provide the structural basis for roads, building pads, or parking lots. This research is based on the stabilization of soil by using calcium-carbide-residue (CCR) and fly ash (FA). CCR is considered a by-product of the acetylene-based gas industry. Since it has no recovery value, it is usually dumped on open land or in a landfill in India. CCR contains lime that increases the pH of the soil, causing the alumina and silica naturally present in clayey soils to dissolve. The chemical reaction of alumina and silica with the calcium in the soil produces calcium-silicate-hydrates (CSH) and calcium-aluminate-hydrates (CAH). The interactions between CSH and CAH are similar to those found when working with cement. They improve the bearing capacity of soils by forming long-term, permanent bonds. In this study, we are investigating how industrial waste products can improve the strength of clayey soils, which is critical for improving the sustainability and resilience of soils. In particular, over years, improvement techniques have
