Using of steel fiber and ultra-fine mineral additives to manufacture the ultra high performance concrete

Abstract

Using of steel fiber and ultra-fine mineral additives with superplasticizer to manufacture the Ultra High Performance Concrete component with good workability, very high compressive strength, suitable for the especially important transports and constructions. When replacing the binder with (10÷30)% Silica fume and 25% Blast Furnace Granulated Slag, and the steel fiber with the content of 1,5%, combined using of reasonable superplasticizer, the concrete will be manufactured with compressive strength over 100MPa; the designed concrete to meet the technical requirements for constructions and transports in Vietnam.
