Claim 18:
19. A method for in situ rapid testing for assessing quality of a concrete test specimen at a test area on an outer surface thereof, the method comprising the following steps:
providing a sustained static pressure of a test fluid to the test area on the outer surface of the concrete test specimen, the static pressure being an elevated pressure equivalent to submerging the concrete test specimen under a predetermined depth of water;
measuring the static pressure of the test fluid over a test period to create a multiplicity of test measurements;
recording the multiplicity of test measurements to create a test data set;
analyzing the test data set to determine a test result; and
reporting the test result,
the step of analyzing the test data set comprising sub steps of:
creating a validation standard; and
comparing the test data set against the validation standard to determine the test result,

the sub step of creating a validation standard comprising testing one or more concrete samples of known quality to produce a validation data set,
the validation standard comprising either a threshold value, a slope of a line, or both, derived from the validation data set, and
the method further comprising the following steps:
identifying the concrete test specimen and the test area on an existing concrete structure;
attaching a system for in situ rapid testing to the concrete test specimen around the test area; and
using the system for in situ rapid testing to provide the sustained static pressure of the test fluid to the test area.
