Project description

The objectives of this project are the following: (1) Design and fabricate the most advantageous test apparatus that will accommodate concrete with #57 while adapting to AASHTO T334. (2) Define the dimensions and specifications for the new test apparatus. (3) Create the resulting Florida Test Method. (4) Use the new apparatus to assess FDOT approved mix designs over the spectrum of shrinkage risk. (5) Develop a shrinkage profile analysis protocol or recommend commercially available software. (6) Develop an FDOT calibration/baseline mix recipe for use by all in a “comparative” approach and the shrinkage profile of a proposed mix compared to the baseline mix. (7) Set preliminary threshold for bridge deck concrete exclusion based on the results of the developed analysis protocol.
