Etude des caractéristiques physico-mécaniques des bétons de sable à base de fumée de silice

Abstract: Résumé. Les bétons de sable font partie des matériaux de construction permettant de valoriser des ressources naturelles en sable. Afin de les exploiter dans différents domaines de construction on doit améliorer leurs caractéristiques mécaniques et physiques (avoir un retrait modéré). Les bétons de sable posent le problème du retrait important par rapport aux bétons ordinaires ainsi que de résistances à la compression modérées. Vu leur effet positif sur la résistance à la compression à jeune âge, on a pensé à u… Show more

“…The extension of these results to the solid and liquid media shows that the pure electrolytic conductivity is a function of average temperature. The theoretical approach to the study of the apparent conductivity of a porous medium according to the average temperature may be conducted based on parallel series model [11], [10], [15] [19]. This approach as we have just shown for porous composite materials, would fit better for the case of our samples made of earth.…”
