Consequence of Cement Constituents, Mix Composition and Curing Conditions for Self-Desiccation in Concrete.

Persson, Bertil LU (2000) In Materials and Structures 33(6). p.352-362
Abstract
This article outlines an experimental and analytical expression study on the consequence of cement constituents, mix composition and curing conditions as regards self-desiccation in concrete. For this purpose nine concretes with three values of w/c (0.32, 0.38 and 0.50), based on two types of Portland Cement, were manufactured. Five per cent silica fume was used in one third of the concretes as calculated on the basis of the cement content. The measurements were done at 1 and 6 months’ age. An analysis of the conditions of the measurements was performed. Parallel tests were performed on strength. The results indicated high influence of w/c, age and cement type on self-desiccation. The curing conditions only influenced internal relative... (More)

The curing conditions only influenced internal relative humidity and strength. The study was performed at Lund Institute of Technology 1997-1998.

Les lignes générales de cet article ont trait à une étude numérique expérimentale portant sur les composants du ciment, la composition des mélanges et les conditions de durcissement par rapport à l’autodessication du béton. Neuf bétons fabriqués à base d’un mélange d’eau/ciment variant entre 0,32 et 0,50 et sur deux types de ciment Portland ont été retenus pour cette étude. Un tiers des bétons contenait 5% de fumée de silice et ont été calculés sur la base du contenu du ciment. Les mesures ont été réalisées sur des bétons âgés de 1 et 6 mois. Des tests sur la résistance out été effectués en parallèle. Les résultats montrent que le rapport eau/ciment, l’âge et le type de ciment sur l’autodessication ont une grande influence. Les conditions de durcissement ont seulement influencé les mesures de l’humidité relative interne. Cette étude a été réalisée entre 1997 et 1998 au sein de Lund Institute of Technology. (Less)
