Abstract

Abstract

On the basis of the C120 concrete with ultra-high strength,polypropylene fibre was added and such tests were taken for concrete as early shrinkage,breaking performance,splitting and tensile strength,brittleness cracking under high temperature．It turned out that the development of concrete crack was limited by polypropylene fiber|as the increases of fiber volume fraction,the toughness of concrete was improved．The splitting and tensile strength and the ratio of tension and pressure were also increased for C120 polypropylene fiber concrete,the brittleness of concrete was improved obviously．The high temperature embrittlement of explosion had been overcome,which made C120 ultra-high strength concrete obtain high performance．
- polypropylene fibre,
- C120 concrete with ultra-high strength,
- high performance concrete,
- brittleness,
- fireresistance test
