Tijolos de terra crua estabilizados com fibras de coco verde: alternativa para habitação de interesse social

Abstract

This assignment proposed the use of green coconut fiber built to land as raw material alternative to the construction of adobe bricks. The fibers were donated by EMBRAPA, thru a partnership, where it is produced in its Benefaction of the Bark of Green Coconut Unit approximately of 530 tones/year of crude fiber. The fiber inserted to adobe acts as a main structure due to the presence of cellulose, lignin and hemicellulose act giving greater cohesion between the components. As methodological basis, Battistelle (2002) was adopted. 8 bricks with fiber in 10% in volume and 8 bricks without fiber sample (soil) were manufactured as a reference and the Standart Compression test took place according with the Brazilian brick mass of baked clay Standart (NBR 6460/83 and NBR 8492/84), once there is not a specific standard to the bricks of raw land. The bricks with the presence of fiber obtained increase of 25% in the resistance comparing to the reference sample. One can infer that the use of fiber of green coconut incorporated to the adobe bricks is a viable alternative to the development of houses benefit social.
