Abstract

An experimental program was designed and carried out to study the residual compressive behaviour of high-performance concrete (HPC) with blast-furnace-slag (BFS) at elevated temperatures ranging from 20 to 800 [deg]C. The residual cube compressive strength is examined and the relationship between the residual compressive strength and temperature is investigated based on the heated cube specimens (100 x 100 x 100 mm3) tested on a universal test machine. In addition, on the basis of the heated prism specimens (100 x 100 x 300 mm3) tested on an electro-hydromantic rigidity servo test machine, the complete stress-strain curves are obtained, and the effects of temperatures on the residual prism compressive strength, the strain, and the elastic modulus etc are analysed. An approximate formula for the stress-strain relationship of HPC-BFS after exposure to temperatures is proposed.
