Abstract

Este trabalho propõe a utilização da fibra de coco verde incorporada à terra crua como material alternativo na construção de tijolos de adobe. As fibras foram cedidas a partir de uma parceria com a EMBRAPA, onde é produzido em sua Unidade de Beneficiamento da Casca do Coco Verde cerca de 530 t/a de fibra bruta. A fibra inserida ao adobe tem características de agir como um esqueleto principal devido à presença de celulose, lignina e hemicelulose atuarem conferindo uma maior coesão entre os componentes. Como base metodológica, adotou-se Battistelle (2002). Foram confeccionados 8 tijolos com fibras no traço de 10% em volume e 8 tijolos sem fibras (solo) como amostra de referência e realizou-se o ensaio de compressão simples segundo as normas brasileiras de tijolo maciço de barro cozido (NBR 6460/83 e NBR 8492/84), devido à inexistência de uma norma específica para os tijolos de terra crua. Os tijolos com a presença de fibras obtiveram aumento de 25% na resistência em relação à amostra de referência. Pode-se inferir que a utilização da fibra do coco verde incorporada ao adobe é uma alternativa viável economicamente para a construção de habitações de interesse social. ---------------------------------------------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.
