Mixture Development for Renewal Plasters of Historical Buildings and Determination of Basic Properties

Popis výsledku v původním jazyce

The lime plasters are damaged more easily than plasters with hydraulic or pozzolanic reactive admixtures. Therefore, it is reasonable to design renewal plasters for historical buildings based on lime putty and admixtures with pozzolanic properties. Pozzolana materials form first a solid structure of CSH compounds, later calcium carbonates. In this paper, metakaolin, grinded enamel glass and grinded brick pottery were used as pozzolana materials in lime-pozzolana plaster mixtures. It can be concluded that the most important parameter of the lime-pozzolana plaster studied in this research compared to the lime plaster is a significant increase of both compressive strength and bending strength without using cement that was not used in buildings older than100 years. The plaster with grinded brick pottery and the plaster with grinded enamel glass achieved better 28-days compressive strengths than the plaster with metakaolin. Therefore, all studied plasters can be successfully applied in hi.
