Afectación en la resistencia a compresión de probetas cilíndricas empleando curado de sellado con polietileno y curado por inmersión

Abstract

The present experimental work was carried out in the materials behavior laboratory of the Faculty of Civil Engineering. 24 cylindrical concrete specimens were made governed by a design in which a compressive strength of f'c = 21 MPa is reflected. The materials that make up the concrete mix were obtained from the - Tuco León, quarry located in the Pasaje canton, these aggregates were subjected to a series of tests to determine their properties and check if they meet the technical specifications. The ACI 211.1 methodology was used for the design of concrete mixtures, obtaining the necessary volumes of materials for the mixture based on a water-cement ratio (W/C) which depends on the design resistance. Then we proceeded to prepare the concrete mix with the dosage calculated for the 24 cylinders, and it was left to set for a period of 24 hours. The following day the cylinders were stripped and 12 cylinders were subjected to curing by immersion and the other 12 cylinders to curing with polyethylene, to proceed with the breaking of the first 6 cylinders after 7 days and to analyze and compare the results obtained from the compressive strength in both curing methods. Breakage tests were carried out at 7, 14, 21 and 28 days after stripping. The results obtained in the laboratory of both curing methods were finely analyzed and compared.
