Determinación del porcentaje óptimo de vidrio granular como aditivo en la mezcla de hormigón y su influencia en la resistencia a compresión

Abstract

The investigation of new components used in concrete mixtures addresses an arid element, recycled glass as an additive to minimize the impact that the concrete industry produces on the environment, costs related to raw materials for construction, innovation through of the reuse of these materials, where at the same time the volume of waste generated both at home and industrial level is reduced, causing social and ecological benefits. In the present experimental work, the optimal percentage of granular glass as an additive in the concrete mixture and its influence on the compressive strength were determined. The stone materials (gravel and sand) were acquired from the Anzu Mine located in the Tena ty, Puerto Napo Parish, the tests of the INEN and ASTM standards were carried out on the fine and coarse aggregate in the laboratory of the Faculty of Civil Engineering and Mechanics; Likewise, the dosage was carried out by the Optimum Density Method for a design resistance to compression of 210 kilograms per square centimeter at 7, 14 and 28 days of age, adding to the mixture percentages of granular glass ranging from 1 to 5 percent according to the weight of the solid materials (gravel, sand, cement), specimens without granular glass were also made for the control and comparison of the compressive strength, the price of the cylinders with and without the additive was also paid. . It was identified that 5 percent is the optimum percentage, giving a compressive strength of 218.77 kilograms per square centimeter at 28 days of age, which is 104.17 percent of the design strength.
