Abstract

Recently, the land area for many people has been limited because of industrialization and modernization in Korea. The large-scale constructions like the reclamation development projects have been progressed to resolve this problem mentioned above. Therefore, as many of the usefulconstruction materials as possible are needed to perform the large-scale construction projects. Many studies for the utilization of pond ash which has a similar characteristic of sand have been conducted and there has been often occurred many structural problems on roadbed in winter. Therefore, the characteristics of the freezing and thawing for Controlled Low-Strength Material (CLSM) using pond ash were analyzed and evaluated by unconfined compressive strength test in this study. As a result of this study, it was confirmed that new CLSM using pond ash with cement (8.2% by weight)was able to stand for the freezing and thawing behavior.
