CRACK-Less™ Bridge Concrete 

It is widely accepted that the durability of structures—particularly concrete bridge decks—will be compromised by the presence of cracks. It’s also widely accepted that a major source of cracking is concrete shrinkage. Although research on concrete shrinkage started well over a century ago, our industry has yet to establish a standard and accepted practice for consistently, reliably, and predictably producing concrete structures with minimal or no cracking due to shrinkage stresses. We believe, however, that the industry is on the verge of establishing an accepted practice, coupling newly available tools with an understanding of how various factors impact shrinkage. 

Shrinkage / Drying Shrinkage Cracking

  • Water and paste contents
  • Shrinkage reducing admixtures
  • Aggregates
  • Setting limits
  • Workmanship Practices

Cost Comparison

  • Standard bridge maintenance cost vs. CRACK-Less™ Bridges
