• Abstract:
  The purpose of this report is to discuss a study conducted on twenty separate mix designs of concrete and the effects of ; the aggregate type, moisture content, and temperature on the coefficient of thermal expansion(CTE). These results are to be used ; for the knowledge of proper choice of mix design for placement of concrete in structures dependent upon the moisture and ; temperature variations of the area. ; There will be three separate types of tests performed to evaluate the effects on the concrete. The three tests are the ; AASHTO TP60-00 test, Danish T1-B method, and the Strain Gage method. An ANSYS program will be used for a Finite ; Element Analysis(FEA) to be performed for comparison of the capability of FEA in calculating CTE. ; The results concluded in this report showed that humidity was not as great of a controlling factor as the aggregate type. The ; major controlling element was the aggregate due to the concrete’s composition being approximately seventy percent aggregate ; and with the different mixtures porosities and accumulated moisture not having as great of an impact on the CTE.
