In some embodiments, a system for automatically evaluating slurry properties includes a down-hole measurement device configured to be lowered into slurry provided in an excavated hole, the measurement device comprising an outer housing, a flow pump, a flow meter, and a differential pressure sensor, wherein the flow pump is configured to pump slurry through the flow meter, the flow meter is configured to measure a flow rate of the pumped slurry, and the differential pressure sensor is configured to measure a difference in pressure between the pumped slurry and the slurry outside of the measurement device.Engineering, Industrial Engineering
Competitive Advantages:
Estimates the strength of concrete, Reduces the size of the equipment, Smaller diameter hole, Reduces the consumption time.
In one embodiment, a concrete strength testing system includes a core drill having a core barrel, a press associated with the core drill that is configured to drive the core barrel into concrete to be tested, a force sensor associated with the core drill that is configured to measure a force with which the core barrel is driven into the concrete by the press, and a depth measurement device configured to measure a depth into the concrete to which the core barrel is driven by the press.Researchers at USF have developed a technology that uses data collected from a core drill in order to determine the compressive strength of the concrete instantaneously. The strength is determined instantaneously and continuously over a given length and with a much smaller diameter hole. The method helps to reduce the size of equipment required and the influence of the coring on the structure, while still allowing the extraction of core sample for verification and calibration. This method eliminates the need for extraction of the large concrete cylinder samples currently required for the testing of the concrete strength.
