Resistencia A La Compresión F’c=210 Kg/cm² Con El Reemplazo Del Cemento En 9%, 11% Y 22% Con Vidrio Molido, Cajamarca 2023

The main purpose of this research was to analyze the axial compressive strength of a concrete F'c = 210 Kg/cm2 incorporating glass as an ecological material and determine the appropriate percentage according to the evaluated. To achieve this, a partial replacement of cement was carried out with the following percentages (9%, 11% and 22%) of ground glass, in order to compare conventional or pattern concrete with an ecological concrete explained above. The study began with the analysis of the physical - mechanical properties of the aggregates that concluded with the determination of their granulometry, unit weight, moisture content, specific weight and their absorption. Next, the concrete mix was designed based on cement replacement percentages, using a 3-4" (inch) slump to ensure adequate workability of the material. A total of 72 cylindrical 6" x 12" samples were prepared using conventional concrete and replacement samples for the three percentages. The objective was to determine the optimal ground glass replacement percentage for an f'c = 210 kg/cm2. Concrete core fracture tests were performed 7, 14, and 28 days after entering the curing pit. The appropriate percentage for the mix design resulted in 11% cement replacement, as 312.64 kg/cm2 was recorded at 28 days of curing, representing a 48.88% increase in strength.
