Performance-Based Proportioning

A performance-based mixture proportioning method has been developed by the National Concrete Pavement Technology Center at Iowa State University. Many prescriptive specifications for concrete mixtures do not meet the specific needs of individual concrete applications, whereas optimized mixtures can be more customized and are sustainable and cost-effective. The performance-based proportioning method evaluates and selects materials and analyzes the interaction between them. There is a spreadsheet tool to help users implement this method.
