The Analysis about Economical Composition in Ultra High Strength Fiber Reinforced Concrete

In manufacturing Ultra high strength fiber reinforced concrete(UHSFRC), steel fiber, super-plasticizer and silica fume are important but they are imported materials therefore very expensive. consequently it is necessary to find substitutes of them or to develop producing techniques in order to manufacture UHSFRC economically. In this study, we investigated if it was possible to substitute blast-furnace slag instead of silica fume and steel fiber of home manufacture instead of one of overseas manufacture.
