Abstract:
This paper presents a numerical tendency model for evaluation of heat and strength development for concrete containing fly ash in different amounts. With the presented model, parameters for heat and strength development calculations in early age can be calculated. It facilitates the possibility to evaluate e.g. form removal times and estimations of need for protection against early freezing for concrete mixes containing fly ash in different amounts.
