Resumen
La presente investigación se realizó con la finalidad de analizar los efectos que produce el uso de agua y arena mar en el hormigón.
Para ellos se utilizaron agregados de las cantera Huayco y Antropevi, arena y agua de mar proveniente de Villamil Playas, Cemento, los cuales fueron sometidos a ensayos granulométricos, de resistencia, gravedad específica, absorción y peso unitario.
Se realizaron tres fases para la preparación de los especímenes, donde se analizo el comportamiento del hormigón utilizando muestra de agregados para conocer sus propiedades, la primera fase consta del diseño patrón con agregado Huayco (arena de rio, piedra y agua potable) con diferentes resistencias pero con un asentamiento constante, la segunda y tercera fase consiste en la variación de agregados: el primer diseño consta de arena de mar, piedras Huayco y agua potable y el segundo utilizando arena de mar, agua de mar y piedras Huayco para conocer
el porcentaje de resistencia con referencia, del diseño patrón con edades de
7,14,28,45,60 días.
The present investigation was did with the purpose of analyzing the effects that the use of water and sea sand in the concrete. For this purpose, sand and limestone Huayco, sand and water of sea from Villamil Playas and Cemento Holcim Fuerte , which were subjected to granulometric tests, resistance, specific gravity, absorption and unit weight. Three phases were used for the preparation of the specimens, the first phase consists of the pattern design with aggregate Huayco (river sand, stone and drinking water) with different resistances but with a constant settlement, the second and third phase consists in the variation of aggregates: the first design consists of sea sand, Huayco stones and drinking water and the second using sea sand, sea water and Huayco stones to know the percentage of resistance with reference, of pattern design with ages of 7,14,28, 45.60 days.
