Abstract

This paper presents an example of the use of microcomputers in the study of the durability of reinforced concrete in which silica fume was used to replace part of the ordinary Portland cement. A thermogravimetric balance, a voltage-driven permeation apparatus, a corrosion apparatus and a mercury intrusion porosimeter were connected to the computer network. The data obtained from the experiments were assembled into a ‘spreadsheet’ for analysis. A total of 96 different measurements were made and a further nine properties calculated. Statistical analysis of variance and multiple regression allowed the determination of the effect of basic parameters on the durability properties of silica fume concrete.

Resume

Cet article donne un exemple de l'utilisation de micro-ordinateurs dans l'étude de la durabilité du béton armé dans lequel des grains de silice de l'ordre du micromètre ont été utilisés pour remplacer une partie du ciment Portland ordinaire. Une balance thermogravimétrique, un appareil de propagation alimenté électriquement, un appareil de mesure de la corrosion et un porosimètre à mercure ont été connectés au réseau informatique.

Les résultats expérimentaux ont été regroupés dans un système de traitement de données pour l'analyse. Un nombre total de 96 mesures différentes a été effectué et 9 propriétés supplémentaires ont été calculées. Une analyse statistique de variance et de régression multiple a permis la détermination de l'effet de paramètres de base sur les propriétés de durabilité du béton à base de grains de silice.
