Claim 19:
20. The method according to claim 19, the system for in situ rapid testing comprising:
a pressure fitting configured and adapted to deliver the test fluid at the sustained static pressure to the test area;
a gasket configured and adapted to seal the pressure fitting to the outer surface of the concrete test specimen around the test area;
a support structure configured and adapted to secure the pressure fitting with respect to the outer surface of the concrete test specimen and the gasket under one or more forces created by the sustained static pressure of the test fluid;
a pressure source configured and adapted to generate the sustained static pressure of the test fluid;
a plumbing structure configured and adapted to deliver the test fluid from the pressure source to the pressure fitting;
a pressure measurement device configured and adapted to measure the sustained static pressure of the test fluid, creating a series of pressure measurements over time; and
a data acquisition module configured and adapted to record the series of pressure measurements over time,
the pressure fitting of the system for in situ rapid testing comprising a round pipe flange with a pipe flange sealing surface configured and adapted to compress the gasket against the outer surface of the concrete test specimen around the test area when acted upon by the support structure,
the pipe flange sealing surface being a substantially flat surface, a convex surface, or a concave surface,
the gasket of the system for in situ rapid testing being configured and adapted to seal against the outer surface of the concrete test specimen around the test area when acted upon by the pressure fitting,
the support structure of the system for in situ rapid testing being configured and adapted to transfer a force between the pressure fitting and the concrete test specimen, causing the pressure fitting to compress the gasket against the outer surface of the concrete test specimen around the test area,
the round pipe flange of the system for in situ rapid testing having an outer flange diameter,
the outer flange diameter being measured in a first plane parallel to the outer surface at a center of the test area when the pipe flange is compressing the gasket,
the support structure being contained within a support footprint diameter measurable in the first plane,
the support footprint diameter being less than 2 times the outer flange diameter,
the support structure comprising one or more fasteners mounted directly in or on a first surface of the concrete test specimen,
the first surface of the concrete test specimen being the outer surface of the concrete test specimen or a surface other than the outer surface of the concrete test specimen, and
the support structure comprising a clamping member configured and adapted to apply force to the pressure fitting without penetrating or mounting into the concrete test specimen.
