Estudo de dosagem de bloco estrutural de concreto com adição de fibra de sisal

Abstract

The industry of concrete structural blocks is growing worldwide and has a high energy consumption due to the use of cement as the main input. Nowadays, in the scenario of extreme pollution on the planet, it is urgent to study more sustainable ways to produce the block - maintaining or increasing its resistance - replacing cement with a material that is more economical from an energy point of view. This work presents an analysis of the contribution of sisal fiber added to the concrete structural block in terms of strength and energy consumption. For this, the performance of the block with and without fiber addition were compared. It was concluded that the variance between the blocks with the addition of fiber makes it unfeasible for structural use. Despite this, the fiber can still be considered for use in sealing blocks
