In our country, heating systems of domestic housing space are mainly applied with floor radiation heating system using hot water pipe. This system has undesirable defects such as crack of cement mortar floor caused by drying shrinkage and irregular temperature distribution. Recently, for solve this problem, blend type with cement mortar and expansive additives or polypropylene fiber use. However, these methods have little effect due to not established construction method such as condition of the actual spot and the lack of blend characteristic. Therefore, in this study, strengthening methods of cement mortar floor are investigated to prevent the cracks using expansive additives, polymer, super plasticizer and silica fume.
