摘要
To provide a method of predicting a heat insulation temperature rise amount of a fly ash-containing concrete which is high in practical use value as mass concrete from composition of the fly ash-containing concrete.SOLUTION: The present invention relates to a method of predicting a heat insulation temperature rise amount of fly ash-containing concrete that uses following formulas (1) to (4) and a unit ordinary Portland cement amount (Wc) to predict the heat insulation temperature rise amount of the fly ash-containing concrete. In the formulas (1) to (4), Q(t) is a heat insulation temperature rise amount (°C) on a day of a material age t, Qa final heat insulation temperature rise amount (°C), r a coefficient of regression affecting a gradient of a curve that the formula (1) draws, s a coefficient of regression affecting a shape of the curve that the formula (1) draws, and ta constant corresponding to an induction period of hydration reaction of the cement.SELECTED DRAWING: Figure 5
