Effect of Eggshell Powder in the Index and Engineering Properties of Soil
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 11, Issue 7
Abstract
Soil is one of the most important materials used in a variety of construction projects including earth canals and earth dams. The fact that soil may provide all the resistance characteristics necessary for a project illustrates the importance of various methods used to improve soil quality. Most of the failures of soil have been attributed to poor strength. Stabilization of soil by adding lime, cement, bitumen etc. are expensive and therefore require an economic replacement. In egg consumption, Tamilnadu stands second place in India. Hence a huge amount of eggshell wastes are produced every year. In the absence of an effective waste disposal, the utilization of eggshell for soil improvement will be a welcome development. In this paper, we studied the suitability of egg shell powder as a possible additive material to improve the strength of soils. Soil samples were collected and stabilized with eggshell powder in proportions of 0.5% to 5.5% at 0.5% interval by dry weight. The index and engineering properties were carried out to access the behaviour of soil with the addition of eggshell powder. The unconfined compressive strength test was carried out with and without delay in compaction. Addition of eggshell powder to soil sample lead to increase in unconfined compressive strength. The maximum unconfined compressive strength was attained at 3% eggshell powder stabilization. The unconfined compressive strength was increased in the delayed compaction than the without delayed compaction. The use of eggshell powder as an additive will therefore improve the strength of soils; however, using eggshell powder quantities in excess of 3% may not yield ample results.
