This article presents the results of a study on the behavior of the compressive strength of a reference concrete formulated by the Dreux-Gorisse method, varying the dosage of water and cement by +/-10%, +/-20%, and +/-30%. The strength obtained for the reference concrete was 13.04MPa. However, an excessive change in the water dosage resulted in strengths of 8.438MPa, 7.05MPa, and 4.73MPa respectively for the dosages of +10%, +20%, and +30%. A deficient change in water dosage produced strengths of 14.418MPa, 15.465MPa, and 17.11MPa for the dosages of -10%, -20%, and -30%. For an excessive change in cement dosage, the strengths were 13.496MPa, 15.936MPa, and 21.575MPa respectively for the dosages of +10%, +20%, and +30%. A deficient change in the cement dosage showed strengths of 6.271MPa, 5.26MPa, and 3.207MPa for the dosages of -10%, -20%, and -30%. These results demonstrate that variations in these two components significantly affect the compressive strength of concrete. However, the change in cement dosage has a far greater impact on compressive strength than that of water.

Cet article présente les résultats d’une étude portant sur le comportement de la résistance à la compression d’un béton de référence formulé par méthode Dreux-Gorisse et faisant varier le dosage en eau et en ciment de +/-10%, +/-20%, et +/-30%. La résistance obtenue pour le béton de référence a été de 13,04MPa. Toutefois, une variation en excès du dosage en eau a entraîné des résistances de 8,438MPa, 7,05MPa, et 4,73MPa respectivement pour les dosages de +10%, +20%, et +30%. La variation en défaut du dosage en eau a donné des résistances de 14,418MPa, 15,465MPa, et 17,11MPa pour les dosages de -10%, -20%, et -30%. Pour la variation en excès du dosage en ciment, les résistances ont été de 13,496MPa, 15,936MPa, et 21,575MPa respectivement pour les dosages de +10%, +20%, et +30%. La variation en défaut du dosage en ciment a montré des résistances de 6,271MPa, 5,26MPa, et 3,207MPa pour les dosages de -10%, -20%, et -30%. Ces résultats démontrent que la variation de ces deux constituants affecte considérablement la résistance à la compression du béton. Toutefois, la variation du dosage en ciment influe largement sur la résistance à la compression par rapport à celle de l’eau.
