Investigation for shrinkage cracking controlling design scheme applying to reinforced concrete structures involving Blast Furnace Slag cement

这项研究的最终目标是促进高炉矿渣水泥的应用，其中钢筋混凝土地面结构和地下结构都是目标。为实现这一目标，本研究重点研究了矿渣微粉水泥混凝土的收缩裂缝控制设计方案。取得了三大成果：1)阐明并解析再现了矿渣水泥混凝土的约束收缩裂缝机理；2)提出了降低矿渣水泥混凝土约束裂缝风险的对策；3)提出并明确了控制收缩裂缝的设计方案。

The ultimate goal of this study is to promote Blast Furnace Slag cement application, where reinforced concrete upper ground structures are targeted as well as underground structures. Toward this goal, this study focused to establish shrinkage cracking controlling design scheme for R/C with BFS cement concrete. Consequently, three major achievements were resulted: 1) clarifying and analytically reproducing restraint shrinkage cracking mechanism of BFS cement concrete, 2) developing countermeasures for reducing restraint cracking risks of BFS cement concrete, 3) Proposing and clarifying shrinkage cracking controlling design scheme.
