Abstract

Relations between defects in self-leveling material and surface quality of concrete slab were experimentally examined. A defect occurrence situation was changed greatly by condition of slab surface. Then, situations were classified into three kinds, "No defect", "Separation" and "Crack". Moreover, it became clear that defect occurrence situation can be predicted by amount of surface moisture and volume of micro voids. Then, when cracks may be occur, amount of cracks can be predicted by surface strength. Those measurements can be easily done in actual construction sites. Therefore, this defect prediction method greatly contributes to performance gain of floors.
