Experimental study on flexural creep of self-compacting concrete reinforced with vegetable and synthetic fibers

This article evaluates the impact of different fiber types on flexural creep self-compacting concretes (SCC). The study focuses effects vegetable fibers (Hemp, [H] and Dis [D]) synthetic (Polypropylene [P]) SCC. To assess SCC, various tests such as spreading, J Ring, compressive strength, strength are conducted. authors developed a test configuration methodology to subject beams measuring 120 cm in length sustained stresses for 200 days. Two curing modes also studied: total (beams exposed air) endogenous protected from air). Moreover, plant were previously subjected two treatments separately; first involves immersing them 5% alkaline solution NaOH (HN DN) second polymer styrene-butadiene rubber (SBR) (HS DS). findings show that treatment by SBR reveals high mechanical properties well good capacity creep. SCC-DS shows an increase 9% 13% with decrease 4% 16% compared SCC without SCC-DN, respectively. These results promising further reflection large scale explore issue strengthening treated fibers.
