Abstract
As one kind of cement-based materials with high strength,high ductility,low porosity and good durability,ultra high performance concrete (UHPC) has gained extensive attention.This paper studied the influence of UHPC constituents on its fluidity and strength development.Results show that the waterto-binder ratio (w/b) is the most crucial factor affecting the properties of UHPC.With the increase of w/ b,the fluidity of fresh mixture improves and strength gradually decreases.Under standard curing condition,the content of silica fume has the minimum influence on strength.When the glass powder content,sand-to-cement ratio,superplasticizer dosage is,respectively,40％,1.0 and 2.5％,the strength of UHPC specimen is the highest.关键词
