Effect of moisture content on the coefficient of thermal expansion of concrete.

The purpose of this report is to discuss a study conducted on twenty separate mix designs of concrete and the effects ofthe aggregate type, moisture content, and temperature on the coefficient of thermal expansion(CTE). These results are to be usedfor the knowledge of proper choice of mix design for placement of concrete in structures dependent upon the moisture andtemperature variations of the area.There will be three separate types of tests performed to evaluate the effects on the concrete. The three tests are theAASHTO TP60-00 test, Danish T1-B method, and the Strain Gage method. An ANSYS program will be used for a FiniteElement 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. Themajor controlling element was the aggregate due to the concrete\u2019s composition being approximately seventy percent aggregateand with the different mixtures porosities and accumulated moisture not having as great of an impact on the CTE
