Behaviour of high‐performance concrete at high temperatures: Some highlights

Abstract

High‐performance concrete (HPC) is now used routinely in building and civil structures. The development of using HPC in structural applications and the growing need for justification of the fire resistance has led several laboratories to carry out research on properties at high temperature. This letter presents some main aspects related to physicochemical changes, thermal properties and mechanical properties for HPC at high temperature. It introduces a State of The Art prepared by the RILEM Technical Committee 227‐HPB (Physical properties and behaviour of HPC at high temperature) and titled “Behaviour of HPC at high temperatures”. This State of the Art will be published in the near future.
