Tekcrete applied to two portland cement beams and one water pipe.On Wednesday, November 5, 2014, the University of Kentucky Center for Applied Energy Research, along with their commercialization partner Orica USA, headed down to College Station, Texas to demonstrate the commercial product, Tekcrete Fast, and its delivery system. This research was supported by funding provided by the U. S. Department of Homeland Security, Science & Technology Directorate, through a technology development and deployment program managed by The National Institute for Hometown Security. 

Tekcrete Fast is a rapidly setting, high strength gunite mix that can be used by rescue personnel to help protect them as they work at a disaster site. It also affords protection to victims trapped in damaged buildings, guarding them against potential collapse and additional harm.

The system is composed of a delivery vehicle capable of concreting or grouting prepackaged fiber reinforced cements, mortars and micro- aggregated concretes that are strong and rapidly setting. A range of compositions of cements have been tested that demonstrate high compressive and bonding strengths after only five hours of curing and structural strength in as little as 15 minutes.    

The demonstration consisted of three damaged Portland concrete beams set in the ground in a vertical manner, to replicate damaged structural beams, as well as a damaged water pipe. Tekcrete Fast was sprayed to repair those damaged items, and then tested three hours later. The beams were placed in a compressive strength machine, and compressed until a failure point was reached. It was concluded that the Portland concrete beams broke outside of the damaged areas where the Tekcrete Fast was sprayed, meaning the Tekcrete Fast was stronger than the actual Portland concrete beams themselves.

The UK CAER Environmental and Coal Technologies research group scientists involved in the demo were Tom Robl, Anne Oberlink, and Bob Jewell.
