The purpose of this study is to investigate the influence on thermal characteristics and mechanical properties of concrete, in case of adding a large amount of fine powders of blast furnace slag, which is an industrial byproduct, according to the purpose of effective use and expansion of use respectively. In this study, using the test apparatus for simple evaluation of mechanical and thermal properties that can evaluate the main design values which are necessary for the thermal stress analysis, various mechanical properties of temperature-affected concrete were investigated and thermal stress analysis using these mechanical values were carried out to investigate the crack prevention effect of concrete added with blast furnace slag fine powder at 60％ or more.
