A computer program based on the single dimensional heat flow equations published previously in TRRL report No LR 561 has been written to calculate temperature gradients in concrete produced by various conditions of shade temperature, radiation and wind speed. In this report it is shown that these equations, previously derived for extreme temperature conditions, can also be used, with suitable boundary conditions, to predict measured values under non-extreme conditions such as are found on days of good radiation in Spring and Autumn. The effect of the variation of individual parameters has been investigated and the program has been used to calculate extreme temperature ranges in various thicknesses of concrete for two selected areas of England, which experience different extremes of weather conditions. Temperature ranges have also been calculated for shade temperature and radiation conditions typical of a good clear day of each month of the year.
