The coefficient of thermal expansion (CTE) of cementitious paste at various ages was studied. Pastes were prepared with various water to binder and fly ash to binder ratios. The CTE of paste increased with age, and decreased with fly ash content, particularly at an early age. A model for predicting the CTE of paste was proposed as a time, material, and mix proportion dependent function. The model was verified with various experimental results and the verification results were satisfactory.
