Concrete mix design method for durability based on particle packing concept

Abstract

Abstract Concrete presents complex behavior, being a difficult material to define the ideal proportion of its constituents. To overcome this challenge, many mix design methods have been developed over time. However, most of these methods do not consider durability parameters during the procedure. Thus, the objective of this article is to present a mix design method for concrete, with properties of workability (slump rating from 50 mm to 220 mm), axial compressive strength (class of 25MPa to 55MPa), and durability as response parameters. From the application of the proposed method, it was possible to create mix design and performance diagrams. It was noticed that all concretes fell into the pre-established consistency class and presented axial compressive strength results close to the predetermined values. Moreover, it was possible to obtain indications of the material's durability.
