Estudo de Dosagem de Concreto Para Traços Intermediários Com Agregados Da Região De João Pessoa

Abstract

The dosage of concrete is a subject well studied and discussed. However, these studies focus on special concretes, such as high-strength, self-compacting, geopolymeric concretes and various others that use additives and additives in their manufacture. However, dosing methods are not capable of providing a trace as accurate as the traits obtained through the dosage study, since these methods can not cover the wide variability of characteristics and rheological properties of the clusters that differ from one place to another. Due to the absence of dosage studies for aggregates from the region of João Pessoa, this work has the objective of studying the dosage of traces with total aggregate content equal to 5 (five), considered as normal trait, and with different mortar contents. The relation water / cement was obtained by attempts, aiming at equal rebates for all the traces. The results presented oscillatory values for the resistances and the slump tests, showing a lack of homogeneity.
