ESTIMATION OF AUTOGENOUS SHRINKAGE OF CONCRETE
Doboku Gakkai Ronbunshu, 1997 コンクリートの自己収縮ひずみの実測値に基づき, セメントおよび混和材の種類, 水結合材比, 有効材齢の関数とする自己収縮ひずみの予測式を提案した. 既往の実測データを用いて本提案式の精度を検証するとともに, RILEMの French chapter の提案する自己収縮ひずみ予測式との比較も行い, 本提案式の適用性について検討した.

Journal of Materials Research and Technology, 2023 The current price of silica fume has a more significant advantage than cement. Application in shotcrete can improve early strength and the durability of shotcrete, and has a good synergistic effect with accelerators to promote setting and hardening. This

Advanced Science, EarlyView.A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Connective tissue graft wall technique for mandibular Class II furcation defects: Two case reports
Clinical Advances in Periodontics, EarlyView.Abstract Background Furcation involvement (FI) represents one of the most challenging conditions in periodontal therapy due to limited accessibility and the progressive interradicular attachment loss that compromises long‐term tooth stability. Deep periodontal pockets in molars and premolars often present as combined defects, including horizontal FI ...

Effects of cooking oil on the shrinkage-reducing of high-strength concrete
Results in MaterialsAutogenous shrinkage is a serious problem for high-strength concrete, which may lead to early-age cracking. Shrinkage-reducing agents are typically used to mitigate the autogenous shrinkage of concrete.
