Filed:

Sep 20, 2012

Appl. No.:

13/623345

Inventors:

ELECTRIC POWER RESEARCH INSTITUTE, INC. - Charlotte NC, US
Maria Silvia Guimaraes Biagini - Charlotte NC, US
John T. Lindberg - Huntersville NC, US
James Joseph Wall - Charlotte NC, US

Assignee:

ELECTRIC POWER RESEARCH INSTITUTE, INC. - Charlotte NC

International Classification:

B29C 39/44

US Classification:

264 31, 425135

Abstract:

An apparatus and method of controlling concrete vibration is disclosed. The apparatus includes a global positioning sensor adapted to provide a location of a vibrator relative to a concrete structure, a recording device adapted to record data during vibration of the concrete, and a data transmission device adapted to transmit the data to a processor for analysis of the data to determine if the vibration is in compliance. The vibrator is adapted to vibrate the concrete to remove air contained therein and promote concrete consolidation.

International Classification:

G01N 33/38

US Classification:

73661, 378 54, 324649

Abstract:

A void detection system for detecting voids in fresh concrete is disclosed. The void detection system includes at least one probe disposed on a vibrator and adapted to detect voids in the fresh concrete, and an indicator in communication with the at least one probe and adapted to receive real-time data from the at least one probe. Upon receiving the real-time data, the indicator relays information to a user indicative of the fresh concrete's consolidation.

International Classification:

G01L 1/24

US Classification:

356 32

Abstract:

A system and method for post-tensioned tendon monitoring includes at least one optical sensor arranged in monitoring proximity to a post-tensioned tendon, a test instrument in communication with the optical sensor, and a processor capable of managing operation of the test instrument, a storage device and a display. The system and method further include a database adapted to contain sensor baseline information and sensor measurement data. The test instrument is capable of sending a first wavelength to the optical sensor and receiving a second wavelength from the optical sensor, wherein at least one of the instrument or the processor is configured to analyze the second wavelength and output sensor measurement data for storage in the database. The processor is configured to calculate an amount of tensile loading which exists in the post-tensioned tendon, based on the sensor measurement data and the sensor baseline data, and to provide an output.
