| Research Abstract |
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.
