Determinación del agua retenida por el agregado en relación a las características superficiales y granulométricas
This study covers point relating to capacity of aggregates to superficially retain part of the water used in mortar and concrete mixtures. It relates this property with the real characteristics of the aggregates. The superficial retention capacity is a decisive factor to determine dosage of mortar and concrete mixtures. The relation between granulometry, modulus of fineness and surrounding surface has accordingly been focused in relation to superficially retained water. Sufficiently generalized analytic expressions have been developped, and later compared with results obtained in experiments based on a process designed for this purpose. The variables are later inter-related using expressions that permitted graphic functions to be developed for correlation with the experimental results, and finally establishing acceptance limits for this process.
