Prediction of fire spalling in fibre-reinforced high strength concrete

Abstract

Abstract. This paper presents results of a study which investigates spalling in small scale specimens of fibre-reinforced high strength concrete exposed to elevated temperatures. A relationship to predict relative maximum pressures was developed, which takes into account parameters such as concrete strength, fibre type and fibre geometry. Also, a blowtorch spalling test method was utilized to investigate spalling in small scale specimens, and a clear relationship between relative maximum pore pressures and spalling was observed.

Some Observations on Testing Conditions of High-Temperature Experiments on Concrete: An Insight from Neutron Tomography

“…Toropovs et al, [13] used a 20 mm-thick glass foam layer in their neutron radiography tests of heated concrete. In [15,17] the authors covered their samples with ceramic fibre board.…”
