High temperature behaviour of concrete : influence of the nature of the aggregates.This study deals with the influence of the nature of the aggregates on the behaviour of concrete undergoing to high temperature stress. Aggregate properties and concrete mechanical performances are usually classified into two categories based on chemical components: calcareous aggregates concretes and siliceous aggregates concretes. However, recent studies showed that high temperature behavior of aggregates within a same group of composition can be particularly different. The relevance of this distinction is discussed through these results.Firstly, a petrographic study (mineralogical composition) on two siliceous and two calcareous aggregates, representative ...
