Análisis del comportamiento mecánico del concreto al adicionar residuos de fibras de caña de azúcar

Abstract

This work was carried out in order to perform an analysis on the efficiency of a conventional concrete in relation to a fiber-reinforcement concrete (cane bagasse), where the mixture of conventional concrete and with fiber have the same percentage of water, cement and gravel, only the fine aggregate that was the one that decreases by adding the bagasse to the concrete varies in a dose of 6 kg/m3 , but in spite of this both concrete is designed to reach the same ultimate endurance capacity. After the dosing, the mixture is made and the concrete is melted and the respective curing days (1,3,7,14,28) are expected for each test (compression, traction, elasticity module, break module), so that the analysis of the mechanical behavior between conventional concrete and concrete with bagasse additions can be carried out in this way. In addition to these, a performance comparison was made between the natural fiber and a synthetic fiber (TUF STRAND SF LAUNCHED). This in order to analyze the potential of natural fiber for the market, through the 1 to 1 analysis, in both the same design was used. The problem of proper curing of cane fiber was presented, since the absorption of water from this fiber is high and the existence of hemicellulose (sugar) this negatively affected the specimens, so two drying procedures were performed to the fiber, in order to adjust this effect of the fiber in the concrete
