During external sulphate attack, the penetration of sulphates within the material is the rate-limiting step. Thus laboratory tests can last a few years before giving usable results. It is possible to shorten the response time by stimulating the penet

In this work, eight types of aggregates that are representative of French production are tested for thermal stability. Afterwards, the influence of this stability on the mechanical characteristic of concrete under fire is studied using strength tests

This paper deals with concrete behaviour under chemical and mechanical degradations. Experimental investigations are described where the effects of the calcium leaching process of concrete on its mechanical properties are highlighted. The calcium lea

In this work, the variations in elastic strain and Young's modulus of high-performance concrete under constant load and increasing temperatures up to 400°C in accidental conditions are studied experimentally. The same study is carried out under serv

Calcium leaching in concrete is highly influenced by the presence of aggregates. We present in this work a modelling framework of calcium leaching which accounts for this fact. Starting from the microscopic point of view, the method consists of the d

In this work, the transient thermal strains of high-performance concrete (HPC) under constant load and increasing temperatures up to 400°C in accidental conditions are studied experimentally. Heating is applied at a rate of 1·5°C/min until success

This paper presents a damage mechanism for high performance concrete at high temperature. Crack opening in concrete is related to water thermal dilation: the aim of this work is to propose a low-cost method for verifying, for a given concrete formula
