Rapidly Deployable Shotcrete System for the Structural Stailization of Shock Damaged Structures

摘要

The University of Kentucky Center for Applied Energy Research, along with Minova USA Inc., and the University of Dundee, developed a rapid strength, high bonding shotcrete system for infrastructure repair and stabilization, at the request of a mandate from the U.S. Department of Homeland Security. This mandate called for development of a material that gains structural strengths very rapidly, as well as the development of a corresponding deployment system to stabilize and repair shock damaged structures to avoid catastrophic failure. Tekcrete Fast® is a material that was developed for this process, and is a specially designed, rapid-setting, and high performance dry-mix shotcrete. This system will stabilize structures like airport runways, tunnels, bridges, and dams that have been shocked and damaged by explosives, or seismic activity, etc. before they fail, by reaching compressive strengths of 41.4 MPa in 3 hours, and 75.8 MPa in 28 days. Additionally, in November 2014, a civil engineering demonstration of Tekcrete Fast® took place in Disaster City, Texas to show that Tekcrete Fast® can help first responders to stabilize building structures.
