Technical Tip training facility located in College Station, TX. It Air compressor includes an extensive array of disaster scenario Tekcrete Fast® simulations for training emergency response (single-bag mix) Water tank professionals. Disaster City includes full-scale, Dry gunite machine collapsible structures designed to simulate various levels of disaster and wreckage, ranging from shock-damaged structures to chemical plant fires and overturned passenger trains, which can be customized for the specific training of any group.1 The UK CAER and Minova USA Inc., with the help of Carl Baur, CCS Group LLC of Millstadt, Water booster/ IL; Jeff Saunders, the Director of the Texas TaskHose reel inline heater Force 1 of the Texas A&M Engineering Extension Service (TEEX); and Dr. Peter Keating from the Fig. 5: Schematic of vehicle layout Texas A&M Civil Engineering High-Bay Struc- tural & Materials Testing Laboratory, dem- onstrated the repairing and testing of damaged or wrecked reinforced concrete vertical beams, simulating catastrophic shocks from an explosion or earthquake to a building or parking-garage-type structure. The demonstration was to show that Tekcrete Fast and its dry-mix shotcrete delivery deployment system can help first responders to stabilize such a structure, so they can get in and out quickly and safely, and to bring any victims of said catastrophic wreckage the help they need. The reinforced concrete vertical beams that were intentionally formed with a missing section and a purposefully damaged beam were placed into the ground and were repaired with Tekcrete Fast. All concrete beams used in the demonstra- Fig. 6: Actual delivery vehicle tion had been placed several months in advance (a) (b) (c) (d) Fig. 7: Disaster City demonstration: (a) placement of damaged vertical beams into ground; (b) shotcrete repair of damaged beams; (c) compression testing of repaired beams; and (d) repaired beam after compression testing, showing that beam failed outside of repaired section 42 Shotcrete • Fall 2015
