ESTIMATION OF BINDING POWER ON POROUS MATERIAL BY AE ENERGY PARAMETER&mdsh;A CASE OF STABILIZATION OF SOIL WITH CEMENT AND RICE HUSK ASH—

Abstract

Quantitative evaluation of binding power is important for porous material. In this study, the binding power in the compressive stress field was estimated by AE energy parameter in the case of stabilization of soil with cement and rice husk ash. As a result, the ratio of compressive strength in water for 28 days to compressive strength in water for 7days was more than 2.4 in stabilization of soil with by replacing more than 50% cement with rice husk ash. Total AE energy was positively correlated with binding power. AE energy seems to be an effective index parameter for evaluationing material quality.
