摘要
混凝土是土木工程领域应用最广泛的水泥基建筑材料,UHPC(Ultra-HighPerformanceConcrete,UHPC)是人们一直坚持追求更高性能混凝土的结果。凭借着优异的力学性能、耐久性能和流动性能,UHPC在土木工程领域的应用正逐步扩大。对UHPC的发展历程、技术指标进行了概述,对UHPC优异的力学及耐久性能做出论述,并指出UHPC也存在着造价高、养护条件苛刻以及纤维分散困难的难题。同时,提出了接下来的研究方向展望,并介绍了本公司的UHPC相关项目研究情况。
Concrete is the most widely used cement-based building material in the field of civil engineering.UHPC(ultra-high perfor‐mance concrete,UHPC)is the result of people’s persistent pursuit of higher performance concrete.With its excellent mechanical properties,durability and fluidity,the application of UHPC in the field of civil engineering is gradually expanding.This paper summarizes the develop‐ment process and technical indexes of UHPC,discusses the excellent mechanical and durability of UHPC,and points out that UHPC also has the problems of high cost,harsh maintenance conditions and difficult fiber dispersion.At the same time,it puts forward the prospect of the next research direction,and introduces the research of UHPC related projects of the company.
