SL材に発生するひび割れの観察および試験体の大きさの影響に関する検討 : SL材のひび割れからみたコンクリート床下地の表層部品質の評価方法(その1)

Abstract

The experiment to observe cracks in self-leveling material constructed on floor groundworks made from various kinds of concrete was carried. As a result, following basic findings were obtained. The observation of cracks should be continued until an increase in width of cracks stop, without constructing any finishing material. The degree of cracks may be indicated quantitatively by the product of length and width. Cracks and separation is not be influenced by specimen size, etc. Based on these findings, the method of predicting cracks by evaluating surface layer quality of floor groundwork will be established.
