Control de la calidad en hormigones con métodos destructivos y no destructivos en columnas y vigas

Abstract

The present investigative work is directed based on the experimentation of a concrete design through laboratory tests, with materials extracted in the Tuco León quarry from the Jubones River in the Pasaje canton, whose objective is to meet the resistance of columns and beams, with the following values. f'c = 210; f'c = 240; f’c =280 〖kg/cm〗^2 which are established in the NTE and INEN standards. The following tests were carried out, granulometry of coarse aggregate (gravel) and fine aggregate (sand), abrasion method with the Los Angeles 3/4 machine, Guapan cement density test, ASTM C188-03 standard, specific density of fine and coarse aggregates, volumetric weight loose fine and gravel, rodded volumetric weight. With the purpose of obtaining the adequate dosage of materials, under the relationship of. cement, gravel, sand and water, for beams and columns. Once the design was done, destructive methods were applied. core extraction and compression, in the same way, non-destructive methods such as: sclerometer. In short, verify that the concrete design (columns and beams) are suitable for operation and meet the requirements imposed by Ecuadorian construction regulations. As a result, the use of the sclerometer is not feasible because it does not give exact values since it may be due to the misuse of the equipment. For the use of the compression method, the dosage of the materials must be taken into account since this can vary the results in resistance at 7 -14 days, after concrete curing.
