Research on technology of ultra high-performance concrete-UHPC, to apply in production in Vietnam

Abstract

ABSTRACT:

This paper presents the results of research on the influence of steel fiber content and curing method on the properties of UHPC. And analyze the advantages and disadvantages of existing concrete intensive mixers on the world to have a basis for equipment selection, curing method as well as oriented composition for investment to manufacture UHPC in construction in Vietnam.

Keyword: UHPC - Ultra high performance concrete, toughness, stress - strain curve in bending, strain curve in tension, dry shrinkage, elastic modulus, intensive mixer, conic mixer, inclined drum mixer.
