Abstract
There exists today no possibility to add larger amounts of commercially available lime hydrate to concretes or mortars. Lime hydrate (Ca(OH)2?) is required on the one hand to maintain in reinforced concretes and mortars an alcalinity at a pH value higher than 9, even during long steel passivation carbonation processes, on the other hand in wall and plaster mortars to allow sealing, crack-healing transformation processes to take place. By producing and using pressed lime hydrate it is possible to obtain lime hydrate-rich binders for concretes and mortars. For that purpose, commercially available lime hydrate is pressed into moulded pieces of various forms and sizes, then crushed and sifted if necessary. The lime hydrate-rich binders produced with pressed lime hydrate require less water during their processing in concretes and mortars, so that shrinking is essentially reduced in comparison with the use of commercially available lime hydrate. These lime hydrate-rich binders are useful for reinforced and non-reinforced concrete and mortar constructions, in new buildings as well as in building renovation, and for wall and plaster mortars, especially in the field of the preservation of monuments.
