Abstract

Abstract

Compared with the traditional steam curing technique of ultra-high performance concrete (UHPC), the UHPC under natural curing technique is of lower energy consumption and boarder application prospects in bridge engineering. Based on the compression test of concrete cubes, axial compression test, flexural test, elastic modulus measuring, and et al, To increase the mechanical properties of UHPC, the traditional production process was improved with conventional materials in the normal temperature curing. The effects of types of water reducers, volume fractions of steel fiber and curing condition on the mechanical characteristics of UHPC were examized. The results showed that the polycarboxylate superplasticizers could improve the compressive strength of UHPC specimens with the same volume fractions of steel fiber better than the naphthalene water reducers. The compressive strength and flexural tensile strength of UHPC specimens were significantly increased with the increase of steel fiber volume fractions within of 2%, and the other mechanical properties of UHPC specimens except the flexural tensile strength, were close to that of the UHPC specimens in the standard curing state.
