Especificacin Normalizada para Agregados para Concreto

ASTM C33/C33M - 13

1. Alcance

1.1 Esta especificacin define los requisitos para granulometra y calidad de agregado fino y grueso (distinto de agregado liviano o pesado) para utilizar en concreto.1.2 Esta especificacin es para ser utilizada por un contratista, proveedor de concreto, u otro comprador como parte de un documento de compra que describe el material a proveer.NOTA 1Esta especificacin es considerada como adecuada para asegurar materiales satisfactorios para la mayora de losconcretos. Se reconoce que, para ciertos trabajos o en ciertas regiones, puede ser ms o menos restrictiva que lo necesario. Por ejemplo, donde lo esttico es importante, lmites ms restrictivos pueden ser considerados atendiendo a las impurezas que ensuciaran la superficie del concreto. El especificador debera comprobar que los agregados especificados estn o pueden estar disponibles en el rea de la obra, con respecto a la granulometra, propiedades fsicas o qumicas o combinacin de ellas.1.3 Esta especificacin es tambin para ser utilizada en especificaciones de proyecto para definir la calidad del agregado, el tamao nominal mximo del agregado, y otros requisitos de granulometra especficos. Los responsables de seleccionar la dosificacin para la mezcla del concreto deben tener la responsabilidad de determinar la dosificacin de agregado fino y grueso y la adicin de tamaos de agregados para combinar si se requiere o aprueba.1.4 Los valores dados ya sea en unidades SI o en unidades pulgada-libra son considerados separadamente como valores estndares. Los valores dados en cada sistema pueden no ser exactamente equivalentes; por ello, cada sistema debe ser usado independientemente del otro. La combinacin de valores de los dos sistemas puede resultar en una no conformidad con la norma.1.5 El texto de esta norma cita notas y notas al pie de pgina que proveen material explicativo. Estas notas y notas al pie de pgina (excluyendo aquellas en tablas y figuras) no deben ser consideradas como requisitos de esta norma.2.
