A method of surveying the condition of an underground enclosure including the steps of (a) positioning at least one transmitter/receiver unit (including an antenna) within an underground, substantially nonconductive enclosure, such that a substantial air gap exists between the antenna and the inner wall of the enclosure; (b) transmitting an ultra wideband (UWB) signal toward at least a portion of the inner wall; and (c) processing the return signal in order to identify the interface between the soil and a region of conductivity different from the soil.

A geopolymer mortar formed by mixing about 35% to about 45% by weight pozzolanic material, about 35% to about 45% by weight silicon oxide source, about 15% to about 20% by weight alkaline activator solution, and about 0. 3% to about 2. 5% by weight copper ion source. The pozzolanic material may be fly ash and the silicon oxide source may be sand. The alkaline activator solution may be a sodium hydroxide solution containing sodium silicate. The geopolymer mortar may have a viscosity in the range of about 25,000 to about 50,000 centipoise. The geopolymer mortar may be formed by further mixing one or more additives, such as surfactants, thermal spheres, anti-sagging agents, adhesion primers, or fibers. The geopolymer mortar may be applied as a protective coating on a surface of a structure.

A geopolymer concrete formed by mixing about 3% to about 43% by weight incinerator fly ash, about 3% to about 35% by weight coal fly ash, about 7% to about 38% by weight alkaline activator liquid, and about 31% to about 70% by weight aggregate. The incinerator fly ash may be derived from a solid waste incinerator facility. The alkaline activator liquid may include a sodium hydroxide solution and sodium silicate. The aggregate may include a fine aggregate, such as sand, and a coarse aggregate, such as gravel.

A conduit survey apparatus having a carriage capable of movement axially down a conduit. The carrier includes a radio frequency (RF) signal generator and an RF signal detector positioned on the carriage along with a controller controlling the signal generator and signal detector. The carrier further includes a waveguide with an open throat transmitting signals from the signal generator and directing received signals to the signal detector. Finally, the carrier includes a waveguide positioner mounted on the carrier and adapted to selectively engage an interior wall of the conduit, wherein the waveguide guide is connected to the positioner such that the open throat of the waveguide is within about 1 inch of the interior wall when the positioner engages the interior wall.

A method of surveying the condition of an underground conduit by positioning a propelled carriage assembly within the underground conduit. The carriage assembly includes (i) at least one transmitter/receiver unit capable of transmitting a pulsed signal toward at least a portion of an inner wall of the conduit, and (ii) a secondary sensor positioned on the carriage assembly. The data derived from the pulsed signal at a given lateral location within an underground conduit is read as is a secondary sensor condition derived from secondary sensor data taken at the given lateral location. Then it is determined whether the secondary sensor condition indicates a basis for a false void detection by the data derived from the pulsed signal and if the basis for false void detection exists, providing an indication of such basis.

A method of surveying the condition of an underground enclosure including the steps of: (a) positioning at least one transmitter/receiver unit (including an antenna) within an underground, substantially nonconductive enclosure, such that a substantial air gap exists between the antenna and the inner wall of the enclosure; (b) transmitting an ultra wideband (UWB) signal toward at least a portion of the inner wall; and (c) processing the return signal in order to identify the interface between the soil and a region of conductivity different from the soil.
