Abstract :

In this study, pumice and zeolite containing high-strength concrete under the environmental impact of MgSO4 as the availability of rigid pavement was investigated. In this context, experiments produced concrete for concrete, compressive strength and abrasion resistance tests were conducted. Physical, chemical and mechanical experiments have been made on the cement, pumice and zeolite which were used as binders in concrete High-strength concrete HSC cement mix design is being realized through the substitution to be 0% pumice + 15% Zeolite (0P15Z), 5% pumice + 10% Zeolite (5P10Z), 10% pumice + 5% zeolite (10P5Z) and 15% pumice +% 0 Zeolite (15P0Z) respectively. HSC to four types were produced. As a result, under the influence of environmental MgSO4 only the surfaces of the remaining HSC candlot powder and calcium sulfoalimunat such as some reaction products were formed. However, damage to concrete, these products were unable to penetrate toward the center of the concrete. On the other hand does not create visible cracks, especially in later times in the edges of the sample was found to be of very light break. Abrasion resistance of concrete values for all types of the predicted values under ASTM C944-99 that have been determined.
