Thermal Properties of the Cement Extruding Panel with Waste concrete Powder

According to increase of the waste concrete occurrence, recycling has being important more and more. This study is to recycle the waste concrete powder, which is occurred in dry-process during recycling of construction waste. We have tried the waste concrete powder to apply as the replacement of the silica powder in cement extruding product. As a result, it is satisfied that the autoclave cured pannel of 50% replacement ratio of waste concrete powder staisty the level of the flexural strength of 14MPa stipulated by "KS F 4735 Extruding concrete panel" was the same thermal properties as base specimen.
