Study on the Properties of Ultra High Performance Fiber Reinforced Concrete

Abstract:

The properties of self compacting ultra high performance fiber reinforced concrete (UHPFRC) are investigated by eliminating the coarse aggregates; optimizing the granular mixture; using a pozzolanic admixture combining with superplasticizers to decrease the water to cement ratio; setting steam heat curing to improve the microstructure; and incorporating steel fiber (about 2% by volume). The properties of UHPFRC specimens, cured by steam curing at 90oC, are investigated. This paper presents some results of studying on the strength, durability and microstructure of UHPFRC with compressive strength above 140MPa.
