Stabilization of Highly Expansive Moreland Clay Using Class-C Fly Ash Geopolymer (CFAG)
Volume change behavior of the Moreland clay, which is full of montmorillonite mineral, is one of the major causes of building and pavement damage in northern Louisiana. Using class C fly ash geopolymer (CFAG) to stabilize expansive soil is not new and becoming more accepted in the industry nowadays. However, stabilizing the Moreland clay using CFAG has never been extensively studied or well documented. In this research, the Moreland clay stabilization with CFAG (5, 10, and 20%) was studied and then its performance was compared with a traditional soil stabilizer which is cement (10%). Consolidation tests were performed 7, 14, and 30 days after the samples were prepared. From the compression index (CC) and swelling index (CS) values it was concluded that even though cement is by far the best soil stabilizer the application of a higher percentage of CFAG, a satisfactory level of soil stabilization can be achieved.
