Abstract
Results of a wide-ranging investigation of the abrasion resistance of concrete are reported and the influence of water/cement ratio, curing, workability, maximum aggregate size and the constituent materials is discussed. Various other tests, namely compressive strength, rebound hardness and permeation (initial surface absorption, intrinsic permeability and vapour diffusivity) are examined for their ability to predict the abrasion resistance of concrete. The initial surface absorption test is recommended for this purpose.
Resume
On rend compte d'une vaste étude de la résistance à l'abrasion du béton, et on discute l'influence du rapport eau/ ciment, de la conservation, de l'ouvrabilité, de la dimension maximale des granulats et des matériaux constitutifs. On examine divers autres essais, tels que résistance à la compression, dureté au scléromètre, perméation (absorption superficielle initiale, perméabilité intrinsèque et coefficient de diffusivité de la vapeur d'eau) en fonction de leur aptitude à prévoir la résistance à l'abrasion du béton. On recommande l'essai d'absorption superficielle initiale.
