Szukana fraza: [Abstract = "For this purpose, the current paper presents a comparison study on the physical\-mechanical behavior and durability against external sulfatic attack on Alfa and Hemp fiber\-reinforced concrete. To assess the effects of sulfatic attack, different types of concrete underwent two aging protocols\: 1\) a complete immersion in 12.5% Sodium Sulfate \(Na2SO4\) solution and, 2\) an accelerated aging protocol which consisted of immersion\/drying in the same sulfate solution at a temperature of 60 degresse C."]
