Geopolymerization Method to enhance the compressive strength of Stabilized Silty Clay Utilizing Coconut Husk Ash, Rice Husk Ash and Sea water for Wall Construction

Abstract

Soil as one of the fundamental components in construction boasts versatile applications in various forms. Silty clay soil is commonly found in various natural environments including riverbanks, floodplains, and agricultural areas. On the other hand, Rice Husk and Coconut Husk are agricultural wastes which contribute to environmental pollution and landfill issues if not properly managed. The utilization of these materials is of significant interest as it has the potential to not only benefit the construction industry but also make meaningful contributions to the preservation of the natural environment. This paper studied the methods for Geopolymerization in enhancing the compressive strength of Stabilized Silty Clay Utilizing Coconut Husk Ash (CHA), Rice Husk Ash (RHA) and Sea water for Wall Construction. It determined the effects of CHA, RHA and Sea water on the strength of compressed earth blocks. There were three different treatments that were considered in this study and replicated three times for the determination of the compressive strength. The soil blocks were cured and tested in 7, 14 and 28th days using Universal Testing Machine (UTM). Results revealed that soil blocks stabilized with CHA, RHA and sea water is effective and can be used on component of partition on load bearing walls.
