However, these sustainable cements have lower reactivity and lower hydration heat. This has a negative effect on the curing process of concrete products. Those who want to be prepared for the use of climate-friendly cements in the future can partially compensate for these disadvantages with active heating. When it comes to choosing the right heating technology, heat transfer using heat exchangers and a hot water circuit has proven to be an efficient method in practice. This can be achieved using different energy sources for hot water production and combined with heat recovery. nFURTHER INFORMATIONRotho - Robert Thomas Metall- und Elektrowerke GmbH & Co.
