Concrete structures are always exposed to the influence of environmental conditions. Mechanical properties of concrete structures undergo changes due to temperature variation. Temperature reading varies with time, season, location and point. This manuscript compared temperature profile of various sizes of rectangular concrete structure. The thickness of the concrete structures ranges from 50 mm to 500 mm at regular intervals of 25 mm. One-dimensional transient heat conduction analytical method was used to generate data for the analysis. Findings showed that time taken for unit change of temperature at centre of rectangular concrete structure varies in a polynomial order with the thickness of the structure. Similarly, the gradient of the dimensionless surface temperature and thickness of structure is steeper as the thickness approaches zero. Furthermore, temperature values at specific points vary as thickness changes. Therefore, mechanical properties of concrete structures also vary from point to point since the properties are temperature dependent. More studies to accommodate temperature distribution through various concrete shapes should be done since temperature gradient through concrete structures depends on geometry. Â Â Â
