Durability of concrete reinforced with alfa fibres exposed to external sulphate attack and thermal stresses
This study focuses on the durability of concrete reinforced with alfa fibres against external sulphatic attack and thermal stresses. Several mix design and tests were made of three types of concrete reinforced with alfa fibres (AC-0.1, AC-1 and AC-1.5; respectively, 0.1%, 1%, 1.5% of alfa fibres in volume), as well as two control concretes: ordinary concrete (OC) and polypropylene fibre-reinforced concrete (PC). To study the external sulphatic attack, the different types of concrete underwent two ageing protocols: complete or total immersion, and immersion/drying at 60 °C as an accelerated ageing protocol in a Na2SO4 solution with a concentration of 12.5% by weight. For the exposure of the various concretes to thermal stresses, three temperature levels were used. The results showed that the concrete reinforced with 1% of alfa fibres is the most optimal compared to the control concrete, and could enable to produce green and durable structural concretes based on untreated alfa fibres.
