Molodid O. Restoration opus signinum plaster arrangement technology

Thesiscontainsexperimentalinvestigationresultsregardingrelationbetweenphysicalandmechanicalindices (porosity, watervapordiffusionresistancefactor, compressionstrength, bondingpower) ofproposedrestorationopus signinum plasterandtechnologyfactors (mortarmixflowability, mixingtimeatmixformation, basehumidity, basepriming, contactlayerspace, mortarmixcompressionmethodandamountofwork, plaster to formworks holding time and evaporation layer availability). Design and analytical studies, the dependence of the duration of the arrangement of plaster and wages from work volumes to 400 m2 for units of two, three and four workers. Restorationopus signinum plasterarrangementtechnologywasdevelopedbasedonexperimentalinvestigationresults. Thistechnologyprovidesforsequentialfulfillmentofbuildingoperations: basepreparation, contactlayerarrangement, plasterlayerarrangement, evaporation layer arrangement.

Laboratoryinvestigationresultswereverifiedinfull-scaleconditions and implemented into practical training.
