Abstract
For the purpose to obtain data for a next revision of the Spanish Concrete Norm about the content of fines in sands fixed to date on 5 % without exceptions, an exhaustive research project has been undertaken. Following, the results of the influence of different contents of calcareous and clayey fines in mortar mechanical properties, are shown, first step to begin the study of this influence on concretes made with limestone aggregate, presently in execution phase. Before those experimental works, a general survey at all the limestone aggregate quarries in northern area of the peninsula corresponding to the Basque Country, was accomplished. By the results obtained it seems that it will be possible to enlarge the limit untill 12-15%, if only a limited presence of clay is assured.

Los husos granulométricos resultantes de estas dos arenas así definidas, teniendo en cuenta el abanico del contenido en finos empleado en cada caso, puede verse en el gráfico 1
Incluso para contenidos de 20 % de finos se mantiene esta tendencia
