Limiting the Total Cementitious Materials Content in Concretes

Project No: 124301

Target Completion Date: November 30, 2027 Structures

About the project:

Current VDOT specifications require minimum total cementitious materials content in all concretes except for the low shrinkage A4 modified concretes for bridge decks. Concrete mixtures with lower than the conventional or specified amount of total cementitious materials can lead to savings in cost and improvement in durability by reducing the occurrence and width of cracks, and thus contribute to sustainability. Through prior experience and references in literature, there are several potential options to achieve the required properties with reduction in cementitious materials. In this study the potential of using a maximum limit on the total cementitious material content to ensure a reduction in the amount required in the current specifications for different classes of concretes will be investigated.
