Abstract

Abstract

At present, the research on mix proportion of ultra-high performance concrete (UHPC) focus on reactive powder concrete (RPC), and the incorporation of coarse aggregate in RPC can reduce the cost and the shrinkage of concrete, but the research on the mix proportion of CA-UHPC is relatively less. The paper discussed the influence of raw materials, production costs and production processes on the development and application of UHPC, and proposed a more economical and reasonable design of UHPC mix proportion. Under the simulated construction environment and simplifying the curing process, by manufacturing 38 sets of UHPC cube test blocks, the water-binder ratio, silica fume content, steel fiber content, coarse aggregate content and curing condition were studied. The influence rules of these factors on the compressive strength of UHPC were given and the reasons were analyzed. In addition, according to the test results, the optimum steel fiber content and coarse aggregate content were given.
- UHPC,
- compressive strength,
- water-binder ratio,
- silica fume,
- steel fiber,
- coarse aggregate
