• Abstract:
  Mixture proportioning is routinely a matter of using a recipe based on a previously produced concrete, rather than adjusting the ; proportions based on the needs of the mixture and the locally available materials. As budgets grow tighter and increasing attention is ; being paid to sustainability metrics, greater attention is beginning to be focused on making mixtures that are more efficient in their usage ; of materials yet do not compromise engineering performance. Therefore, a performance-based mixture proportioning method is needed ; to provide the desired concrete properties for a given project specification. The proposed method should be user friendly, easy to apply ; in practice, and flexible in terms of allowing a wide range of material selection. ; The objective of this study is to further develop an innovative performance-based mixture proportioning method by analyzing the ; relationships between the selected mix characteristics and their corresponding effects on tested properties. The proposed method will ; provide step-by-step instructions to guide the selection of required aggregate and paste systems based on the performance requirements. ; Although the provided guidance in this report is primarily for concrete pavements, the same approach can be applied to other concrete ; applications as well.
