As with all hydraulic binders, higher temperatures may accelerate, lower temperatures may retard the strength development. Even if the ambient application or material temperature is below 10 °C, Chronolith®1 will still yield high early strengths. In this lower temperature range Chronolith®1 features a characteristic reduction of its setting time which may be compensated for by using heated mixing water or appropriate retarders. Temperatures higher than 20 °C will lead to an acceleration of the setting behaviour, as for nearly all cements. In this case we recommend tempering the water or appropriate retarders. After 28 days the strengths correspond to strength class 32.5 (according to EN 197-1).
