Title: EXPERIMENTAL STUDY ON EXPANSIVE CLAYEY SAND MIXTURES
Author: H., Shammat,; M.A., Osman,
Abstract: Clayey Sand (SC) soils are found in different areas in Sudan. Although these soils are classified as clayey sand by the Unified Soil Classification System (USCS), still soils had high values of L.L & P.I and noticeable variations of volume change as their moisture content changes. This has serious effects on the integrity of engineering structures. Index tests were performed for eleven soil specimens to study the expansive behaviour of (SC) soils. Package SPSSWIN computer program was used for the regression analysis of laboratory tests data. The test results were analyzed and presented. This paper concluded that when increasing the sand fraction from 7% to 10% low volume change characteristics and high strength properties were noticed
