The strength development in relation to BA replacement is shown in Figure 5. At 7 D the simple replacement of the OPC with baggasse ash at 10-30 % (CBA10–CBA30) had the compressive strength values close to CBA0. At 14 and 28 D, The results CBA20 had the highest compressive strength of all the mixtures. Based on the strength characteristic results and economics, using 20% BA for partial replacement of OPC is suggested as the optimum content for soil stabilizer.
