Název v původním jazyce

Mechanical, fracture-mechanical, hydric, thermal, and durability properties of lime-metakaolin plasters for renovation of historical buildings

Popis výsledku v původním jazyce

An extensive set of parameters of several lime-metakaolin plasters, including basic material characteristics, mechanical and fracture-mechanical properties, durability characteristics, hydric parameters and thermal properties, is presented. In a comparison with the reference lime plaster without any additives, the experimental results show three- to fivefold increase in strength, about 25% decrease of water vapor diffusion coefficient, 20% decrease of water absorption coefficient and a very high increase of freeze/thaw resistance. Using the lime of very high purity in lime-metakaolin plasters (98.0% of CaO+MgO) is found preferable to lower-purity limes; the main differences are observed in the freeze/thaw resistance, mechanical and fracture-mechanicalparameters. A comparison with two commercial renovation plasters shows that the only notable advantage of the best commercial plaster studied over the best lime-metakaolin plaster is in its lower moisture diffusivity but it can be matched
