Evaluación de la resistencia a compresión de especímenes cilíndricos de concreto simple con reemplazo parcial de residuos plásticos HDPE como agregado

Abstract

The present investigation, entitled "Evaluation of the compressive strength of cylindrical specimens of simple concrete, with partial replacement of HDPE plastic waste as aggregate" sets out as its main objective to carry out an experimental campaign to determine the properties acquired by concrete with resistance of 21(Mpa ) when using High Density Polyethylene (HDPE) as a replacement for fine aggregate in percentages of 10% 20% and 30%. To prepare the concrete mix, the ACI 211 Method was used. As the main condition established by the method, the main materials that are required for this type of mix had to be characterized, such as: Type I Portland Cement, fine aggregate, coarse aggregate and as The main novelty is high-density polyethylene. For the characterization, the Colombian technical standards were followed, which describe the parameters to be taken into account for each one of them. Following this, the dosages were made for the replacements of HDPE by fine aggregate in the percentages already described above. Once the mix design and its dosages are defined for each percentage, the concrete is emptied into 4 "x 8" cylindrical specimens to obtain the cylindrical specimens with HDPE replacement. Once the concrete has set, the properties it acquires are defined. This by means of a series of tests where the samples are subjected to compression with ages of 7, 14 and 28 days in a dry state. Finally, in order to assess the viability of this type of concrete with HDPE replacement, a study is carried out and an evaluation of the resistances that it acquires with differences over normal concrete. The tests required for the development of this research were carried out at Laboratorio Daincoc S.A located in the city of Bogotá.
