Abstract

This article is to present the shrinkage characteristic of soft Bangkok clay stabilize with cement and fly ash by using image processing technique. The law materials consist of soft Bangkok clay, Portland cement type 1, and fly ash from Mae Moh Power Plant. The mix ratio of soft clay blended with cement is shown in term of the cement/clay-water ratio which are 0.3 and 0.4. From each mix ratio, fly ash is replaced in the amount of 0, 15, 30, 45, and 60%. For shrinkage analysis, the image processing method of 2D is used together with the PCAS and ImageJ software. The programs can analyze the number of cracks segment, crack length, crack width, and crack area as well as crack intensity factor. Finally, this study will suggest the optimum mix ratio of soft Bangkok clay admixed with cement and fly ash for applying soil improvement practices.
