Problematic Soil

Expansive clays are one of the most widely found soil type across the globe known for their low strength behavior. A number of studies have been conducted in the past few decades to stabilize such soils using various additives. The traditional stabilizers such as cement and lime not only prove quite costly due to their high industrial demands but also result in exhaustion of the available natural resources. This study is based on admixture of a waste originating from leather industry known as limed leather waste which can be utilized as a potential stabilizer and strength enhancer for expansive clays at the construction sites as a replacement to conventional additives. The utilization of the waste besides treating the problematic soil will also solve the dumping issue of the waste itself and will reduce the environmental hazards. It is found from the study that the waste when used in the ash form is capable of improving the compaction and strength characteristics of the expansive soil substantially. A comprehensive increase in soil strength is also achieved through curing. The SEM results are used to explain the microstructural changes in the soil and agglomeration and generation of silicate gel compounds responsible for increase in strength of the soil-ash mixture.

Reinforcing Material

Coir fibers are extracted from the husks surrounding the coconut. Coir fibers can be effectively used as reinforcing material but it has less durability and hence coir fiber coated with kerosene is used as reinforcement in the present study. The objective of the present investigation is to study the strength behavior of expansive soil reinforced with 5mm long randomly distributed kerosene coated coir fibers in 0% (unreinforced), 0.5%, 1% and 1.5% by dry weight of soil. Water absorption (WA) tests were conducted on uncoated and kerosene coated coir fibers. The WA tests were also conducted on kerosene coated coir fibers mellowed for a period of 1 day, 2day and 3 day. Water Absorption Capacity (WAC) of kerosene coated coir fiber reduced as compared to that of uncoated coir. It is found that 1% of coated coir fiber is the Optimum Coir Content (OCC) from view point of Unconfined Compressive (UCC) strength. Splitting tensile strength of OCC reinforced soil is increased by 50% that of unreinforced soil.
