Resumo
The development of an eco-friendly material that can reduce CO2 emission and aggregate value to a natural fiber setting man at the countryside and raising the income of populations from poor regions is a big challenge to the scientific community. In this particular, the lignocellulosic fibers can have an important role once they are a cheap and readily available reinforcement, requiring only a low degree of industrialization for their processing. The main drawback of using lignocellulosic fibers as reinforcement in cement composites is that they can be mineralized inside the alkaline pore water environment of the concrete. In this work, Portland cement was partially replaced by metakaolinite in order to produce a matrix free from calcium hydroxide, avoiding thus fiber mineralization. Cement composites reinforced with 2, 4 and 6% of short curaua fibers, were manufactured. The composites were submitted to four pointing bending tests in order to determine their mechanical behavior. The results obtained indicated that multiple cracking cementitious composites can be obtained using short curaua fibers as reinforcement.
