Concrete, low permeability, compressive strength, water pressure.
Abstract
The purpose of this work was to analyze the behavior of low permeability concrete with compressive strength f'c = 175 kg/cm2, 210 kg/cm2, 245 kg/cm2 and 280 kg/cm2 under high water pressure. During the development of this research, work was carried out in the concrete laboratory and 56 specimens were prepared at the age of 28 days, mainly for tests of compressive strength, indirect tensile strength and water penetration depth at a pressure of 50 m.w.p (meters of water column), according to the European standard UNE-EN-12390-08. Subsequently, through our data analysis we determined that the properties of concrete such as: slump, fresh unit weight, dry unit weight, compressive strength, indirect tensile strength, porosity, absorption, water penetration in concrete. These last two values are necessary to determine the permeability coefficient using the VALENTA equation. Finally, we conclude that concrete with a design of 210kg/cm2 is the most suitable for hydraulic construction, since it favors economic savings and avoids damage to society.
