| Abstract | The excessive use of cement has caused incremental production of greenhouse gases, one the consequences of which is the overheating of the planet. These detrimental effects have highlighted the importance of pozzolanic materials, and accordingly, using alkali-activated concrete pavement instead of cement has been presented as a solution. Moreover, using fiber concrete surfaces is a predominant method to repair the concrete pavement due to the high speed of performance and the reduction of the thickness. For this purpose, various amount of sinusoidal steel fibers, kortta embass and kortta twist were added to the alkali activated concrete pavement. The results showed that with an increase in the fiber percentage, the compressive strength, flexural strength and the energy absorption, splitting tensile strength, impact resistance, skid resistance, resistance against freezing and thawing cycles is enhanced. On the other hand, the thickness of the concrete slab and water penetration into the concrete decreased. However, these cases are somewhat efficient for the sinusoidal steel fibers, and then the process begins to decrease. |
