About the Book

O objetivo deste estudo é caraterizar e quantificar as propriedades mecânicas do betão reforçado com fibras híbridas. A utilização de betão híbrido como fibra de coco e material de juta é adicionada e o cimento é substituído por alguma proporção de escória de alto-forno granulada moída (GGBS). Os ensaios do betão reforçado com fibras híbridas são ensaios de resistência à compressão, à flexão e à tração. Ao misturar e moldar o betão, as fibras são adicionadas com 0,5%, 1%, 1,5% e o comprimento das fibras é de 2 cm. O ensaio dos cubos de betão é o ensaio de compressão, o dos cilindros é o ensaio de tração e o das vigas é o ensaio de flexão. O tempo de cura dos cubos, cilindros e vigas é de 7, 28 e 90 dias. O híbrido compósito significa que os dois ou mais tipos são combinados com uma proporção racional e os seus benefícios para o betão maciço. A maior parte das fibras são adicionadas para aumentar a resistência à flexão e à tração, o que também afecta a fibra de coco e a juta. Mas, segundo muitos investigadores, a adição deste material aumenta a resistência à flexão e à tração, mas diminui a resistência à compressão.
