	High-performance and compatible lime mortars for extreme application in restoration, repair and preventive maintenance of architectural heritage: final report Kabele, P. ; Slížková, Zuzana The final report describes progress and achieved results of the project, which was focused on development of new high-performance and compatible mortars for extreme application in restoration, repair and preventive maintenance of architectural heritage, development of numerical tools for their optimization and simulation and verification of their application on model historical objects. The materials were developed so as to achieve higher effectiveness and prolonged durability compared to classical lime mortars. Detailed record
	High-performance and compatible lime mortars for extreme application in restoration, repair and preventive maintenance of architectural heritage: final report redacted Kabele, P. ; Slížková, Zuzana The final report describes progress and achieved results of the project, which was focused on development of new high-performance and compatible mortars for extreme application in restoration, repair and preventive maintenance of architectural heritage, development of numerical tools for their optimization and simulation and verification of their application on model historical objects.

	Preparation of plaster with increased frost resistance for repair of historic buildings Slížková, Zuzana ; Frankeová, Dita ; Nunes, Cristiana Lara ; Janotová, Dana ; Hauková, Petra The methodology provides basic information on the preparation and use of lime-metakaolin mortar modified with linseed oil in order to increase the resistance of the mortar to freeze-thaw cycles and durability of mortar (plaster). The mortar will be used in the field of conservation of historic constructions.

	Chemical and mineralogical composition of mortars and plasters from Church of St. Margaret of Antioch in Kopčany Slížková, Zuzana ; Petráňová, Veronika ; Zeman, Antonín ; Frankeová, Dita ; Hauková, Petra The aim of work was analysis of the historical mortars from the 9th century. This unique specimens with exceptional durability were provided by restorer during the renovation of the church. Small amounts of samples allowed to perform only the microscopic analysis, which results in the characterization of aggregates and mortar binder. The composition of the mortars is changing as binder shown of aerial, dolomitic and hydraulic lime.

	A survey of the mortuary in Ostrovec at Velečín Slížková, Zuzana ; Frankeová, Dita ; Petráňová, Veronika ; Zeman, Antonín ; Hauková, Petra ; Mácová, Petra ; Niedoba, Krzysztof ; Viani, Alberto ; Pérez-Estébanez, Marta ; Zíma, Pavel ; Janotová, Dana This report presents the results of a survey of the mortuary object in Ostrovec by Velečín which has been selected for testing the samples of plaster developed in the project MK NAKI DF11P01OVV008 (High-performance and compatible lime mortars for extreme application in restoration, repair and preventive maintenance of architectural heritage). The survey focuses on the plinth of the morgue, where the plaster repeatedly freezes and falls off after one winter season. Causes of failure of the repairs plasters and material composition of were examined by following techniques:x-ray diffraction (XRD), thermal analysis (TG), optic and electron microscopy, FTIR and Raman spectroscopy.

	Frost resistance of lime-based mortars Janotová, Dana ; Nunes, Cristiana Lara ; Slížková, Zuzana The paper presents several methods for assessing frost resistance of six different lime-based mortar mixtures according to the type of binder. Specimens with three and twelve months of age were subjected to frost resistance test according to CSN 72 2452 standard. Durability of each mortar type was evaluated through mechanical strength, frost resistance coefficient, modulus of elasticity and saturation coefficient. The results obtained point out that the lime-based mortar mixtures tested can only fulfil the frost resistance standard requirements if containing a certain amount of Portland cement. Detailed record
	Frost resistance of lime-based mortars with linseed oil Nunes, Cristiana Lara ; Slížková, Zuzana ; Janotová, Dana The recent findings in mortar additives that grant hydrophobic properties to mortars show that by restraining water penetration, damage from frost and salt can be decreased. Improved durability of lime-based mortars with linseed oil addition has been confirmed making the present formula a promising recipe for mortar reconstructions. Detailed record
	Effect of linseed oil on the mechanical properties of lime mortars Nunes, Cristiana Lara ; Slížková, Zuzana ; Janotová, Dana ; Frankeová, Dita The effect of linseed oil addition in 1.5% by the weight of the binder was studied in two different mortar mixtures: air lime mortar and air lime-metakaolin mortar. Carbonation and hydration reactions were studied by thermogravimetric analysis and flexural and compressive strength were evaluated along curing time: 14 -90 days.) Detailed record
	Problems with the quality of lime mortars modified with metakaolin in the field of conservation of building heritage Slížková, Zuzana ; Frankeová, Dita ; Hauková, Petra ; Janotová, Dana The paper presents a case of failed application of air lime mortar modified with metakaolin as the replacement of decayed or missed render rep. jointing mortar from historic wall. Detailed material characterization of applied mortar results in determination of causes leading to low durability of mortar applied on historic walls. Detailed record
