Development of Rapid In-Situ Testing for Concrete Deck Durability

Assessing durability on-site is a challenging task. An interesting quality check test for the durability of concrete has been developed at Florida International University (FIU) which could be modified for “in-situ” assessment of the durability concrete elements (column, beam, abutments, bridge deck, etc.) in less than 20 minutes. This which would allow for a quick quality control assessment of the concrete components used in Accelerated Bridge Construction (ABC). Following is a very brief description of this novel method. The method quickly assesses the durability of hardened concrete material against liquid ingress, at very high pressure. This proposal aims at relating this behavior to standard durability tests, such as Freeze/Thaw, Rapid Chloride Permeability, Bulk Resistivity and Surface Resistivity tests that are expensive and take a very long time. The entire test lasts 20 minutes. In the developed method, liquid at high pressure is applied to the surface of hardened concrete and time vs. pressure response is obtained.
