Mechanical and hygric properties, namely compressive strength, bending strength, water sorptivity, moisture diffusivity and the water vapor diffusion coefficient, of two innovative lime plasters with pozzolanic admixtures (metakaolin, metashale) and two commercial renovation plasters are studied in this paper. Reference measurements with common lime plaster are done as well. Experimental results show that the analyzed lime-pozzolana plasters are suitable for an application in reconstruction of historical buildings. Their mechanical properties are superior to lime plaster and better or similar to commercial renovation plasters. Their hygric properties are similar to lime plaster or slightly better and comparable with commercial plasters.
The article analyzes possibilities of using additive manufacturing in the building industry, especially in the field of reconstruction of building structures. On concrete examples, growing potential and future perspective of the additive manufacturing technology are demonstrated in the text. There are also presented cases of reconstructions, especially in combination with the 3D scanning method. At other points, the basic principles of this technology are presented, its advantages over conventional technological procedures and the possibility of application of special concrete as a primary material in the context of 3D printing and the construction industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
