In the present research was determined the effect of using the recycled concrete aggregates (RCA) as raw material in the elaboration of concrete for the construction of houses in the city of Huamachuco. Portland cement Type I, 1/2 "and 3/4" gravel, coarse sand and aggregates of recycled concrete were used as raw material for the design of mixtures, these last replacing coarse sand and gravel in the percentages by volume of 50%, 75% and 100% respectively. Specimens of simple concrete and concrete containing RCA were prepared according to Peruvian Technical Standard 339.033, then the compression test was performed on the specimens after 7, 14 and 28 days of curing, according to ASTM C39, so the concrete containing 50% RCA showed the best compressive strength, reaching 200.18 kg/cm2. Also, it was observed that the compressive strength of the concrete containing 100% ACR after 14 days presen...

En la presente investigación se logró determinar el efecto de utilizar los agregados de concreto reciclado (ACR) como materia prima en la elaboración de concreto para la construcción de viviendas en la ciudad de Huamachuco. Se utilizó como materia prima, para el diseño de mezclas, el cemento Portland Tipo I, gravilla de 1/2" y 3/4", arena gruesa y los agregados de concreto reciclado, estos últimos sustituyeron a la arena gruesa y a la gravilla en los porcentajes en volumen de 50%, 75% y 100% respectivamente. Se elaboraron probetas de concreto simple y concreto conteniendo ACR según la Norma Técnica Peruana 339.033, luego se realizó el ensayo de compresión a las probetas, después de 7, 14 y 28 días de curado, según la Norma ASTM C39, así se pudo determinar que el concreto conteniendo 50% ACR presento la mejor resistencia a la compresión, alcanzando 200,18 kg/cm2.
