  • Alternatives for Large Crater Repairs using Rapid Set Concrete Mix®

    Abstract: Research was conducted at the U.S. Army Engineer Research and Development Center (ERDC) in Vicksburg, MS, to identify alternative repair methods and materials for large crater repairs using Rapid Set Concrete Mix®. This report presents the technical evaluation of the field performance of full-depth slab replacement methods conducted using Rapid Set Concrete Mix® over varying strength foundations. The performance of each large crater repair was determined by using a load cart representing one-half of the full gear of a C-17 aircraft. Results indicate that using rapid-setting concrete is a viable material for large crater repairs, and the performance is dependent on surface thickness and base strength.
