The objective of the research presented in this paper is to define the flexural behaviour of thin plates made of UHPC tested under 4-point bending and subjected to different temperature fields. Temperatures imposed during loading are between - 40°C and 100°C and applied to two types of Ductal® (FM and FO). The tests show a negative influence of high temperatures on the Ductal® FO and a positive influence of negative temperatures on the behaviour of both FM and FO Ductal®. In addition, some specimens of Ductal® FM and FO have undergone accelerated aging involving temperature, humidity, UV. This article shows the effects of aging on the behaviour of Ductal®. These exploratory tests demonstrate the interest to predict the behaviour of UHPC for use in extreme conditions which are vis-à-vis high or low temperatures, but also aging conditions.
