Il Nitrato di Calcio come additivo per la produzione di mattoni di cemento

This paper wants to stimulate knowledge transfer from ready mix concrete to concrete brick and element production. The production of concrete elements and bricks 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.

A CONDITION SURVEY OF CONCRETE ELEMENTS WITH CORROSION INHIBITORS

Three wall elements have been stored in the tidal zone in the Trondheim fjord, Norway (average yearly temperature 5°C) for 12 years. Two concrete elements were added either calcium nitrite or calcium nitrate as corrosion inhibitors, while the third element without inhibitor served as reference.
