As mortar on floor-heating system is placed thin from 4 to 6cm, it displays too much cracks by dryness and shrinkage. This problem is not yet solved completely, though many researchers have made various efforts. Even the appropriate guidelines for construction and quality management are not established. This study aims at investigating the cause of cracks in materials, mix proportion, production and construction clear, and preparing the applicable measures against crack through laboratory experiments, mock-up tests and field tests.
