Calcium Nitrate as admixture for concrete block production

Reducing peak hydration heat, energy consumption and optimizing production cycle time


This paper wants to stimulate knowledge transfer from ready mix concrete to concrete block and element production. The production of con- crete elements and blocks needs to be sustainable and cost efficient, and admixtures can help to reach this objectives. Especially partial replacement of steam curing by use of admixtures can be interesting, too. A potential candidate for such an admixture is Calcium Nitrate that is today mostly used as stand-alone admixture or part of formulations in ready mix concrete.
