A review on Comparative study of using Silica Fume and Areca Fiber on Soil Stabilization

Abstract

Abstract The rapid expansion of urban areas and the rise in construction activities have led to a shortage of land with suitable soil conditions. This has forced people to utilize weak soils available locally for construction purposes, employing various stabilization techniques. Urban expansion and construction demand the utilization of local weak soils for building, necessitating the application of soil stabilization techniques. These methods enhance soil strength by altering its properties. This study evaluates silica fume and areca fiber as stabilizers. Silica fume is a pozzolanic and supplementary cementitious material that enhances material properties such as strength, durability, and resistance to chemical attacks and abrasion. Few studies have examined areca fiber as soil reinforcement. Areca fiber (20-30 mm in length) upto 0.6% of dry weight of soil significantly improves engineering properties of soil. Varied weight ratios of silica fume and areca fiber are used based on soil type for optimal conditions. Silica fume stabilizes, and areca fiber reinforces problematic soil, as demonstrated through compaction, UCS, and CBR tests. Utilizing such waste materials is a cost-effective and more sustainable approach in the field of engineering. This research investigates the compaction and strength properties of various problematic soils stabilized with silica fume and areca fiber, providing a comprehensive review of the findings.
