Opis:
In process of execution of the Byzantine-Ruthenian mural paintings the following three stages should be listed as basic: preparation of the lime putty, that of lime mortar, and the making of topping coats. The importance of all the above stages is being emphasized in all written records that have been preserved up to the present day. In addition to technological investigations the above-mentioned documents form the main source of our knowledge in the field of the painter’s techniques in use many years ago. From among the painter’s handbooks and other documents containing professional prescriptions and recommendations the oldest ones are coming from as late a time as the second half of the 16th century. Here should be named the „Tipik” by Nektariy, dated 1599 and a good deal of Russian manuscripts known under the name of „Podlinniks”. Among the Greek painter’s handbooks as the oldest one may be considered „Hermeneya” written after the year 1566. Quite a good deal of „Podlinniks” could be dated as early back as to the 17th century whereas the „Hermeneya” of Dionysos to the first half of the 18th century. The preparation of lime putty represented rather a complex and sometimes time-consuming procedure. Its main features were the mixing of lime with water, working it with the spade and the cleaning. The „Podlinniks” and particularly the „Tipik” provide a detailed description of methods used for removing of diluted salts (s.c. „emchugha”) from the lime by washing them out. The above washing process was aimed at reducing the content of harmful salts and at the same time at decreasing the binding strength of the future topping coat whicji the process had to some extent prevent its cracking. Among prescriptions included to the „Tipik” may be found an „old masters’ ” prescription that recommends the wintering of lime during the winter period and mixing the organic binders to the lime putty. The mortar was prepared from the lime putty with an admixture of suitable fillers. According to prescriptions under discussion the lime putty was mixed with the cut straw (of corn or grass) but also with tow and allowed a period of a few days for so called fermentation. The mortar of the first type served for preparing the lower while that of the latter type the upper topping coat. It was recommended in „Tipik” to add a proportion of sand to the lower layer. From among the fillers in use on the Ruthenian and Russian territories only the tow may be listed while on the Balkan and the actual territory of Turkey straw was used most commonly, and both the tow and straw in Poland. The sand admixture in varying proportions may be found in all the countries concerned. The topping coats for the Byzantine-Ruthenian paintings have underwent an evolution as result of which the s.c. monoliths containing the marble and limestone breakage and the pottery breakage most commonly used on Ruthenian territories were in time replaced by s.c. spongey plasters where in turn an organic matter was used in form of vegetable fibres. The monolithic plasters were applied in the early Byzantine period (the 8 th to the 11th century) and on the Ruthenian territories (the 10th to the 12th century). The origins of that type of plasters should be sought in Roman tradition. A ll the written sources baing in fact prescriptions of a later date list the s.c. spongey plasters only. At the execution of topping coats a careful attention was devoted to the cleaning of brickworks to be coated with the lime mortar as w e ll as to their suitable damping with water. The topping coats were thoroughly tamped and then carefuly smoothed. It was also recommended by „Tipik” to drive m ils into brickwork and, in full accordance with Cennini’s recommendations, to apply the moisture-resistant insulation where the brickworks were moist. The lime mortar was normally thrown starting from the uppermost left-side wall portions gradually moving down to the right side. The particular portions of the s.c. dayworks as a rule comprised the definite compositions. Both „Tipik” and Hermeneya” recommend the application c f the double-layer plasters the lower layer of which should be thinner while the upper thicker one. However, we know from observations made that the single-layer plasters were applied commonly enough (for example, in Macedonia and Serbia). For the Byzantine-Ruthenian paintings found on Polish territories plasters of both types were used. The thicknesses of plasters varied in different countries mainly depending upon the material used for erection of temples and the wall structure and tex tu re. They were thin on ashlars (ranging to a few m illimetres) and thicker on brickwork walls (1 to 4 cm). In addition to differences present in several types of plasters applied for the Byzantine-Ruthenian paintings quite a remarkable number of features common for both types may be named. Suitable fillers and especially the vegetable fibres furnished the plasters with strength and lasting freshness allowing the easier and longer execution of painting using al fresco technique. It were the plasters then that played decisive part in the choice of manner by means of which were executed mural paintings belonging to the Byzantine- Ruthenian tradition.

Opis:
W ostatnich latach kamienice Starego i Nowego Miasta w Warszawie poddawane są remontom. Czy prace te mieszczą się w pojęciu konserwacja-restauracja, czy są renowacją? Wątpliwości budzi przede wszystkim efekt estetyczny – nadanie elewacjom efektu nowości. Konieczność zachowania autentycznego wyrazu artystycznego dekoracji kamienic Starego i Nowego Miasta wynika z faktu, że są to dzieła wybitnych polskich artystów. Poza tym Stare Miasto jest wpisane na Listę światowego dziedzictwa UNESCO. W artykule skupiono się na problemie rozwiązań estetycznych i artystycznych, które są jednak ściśle powiązane z zabiegami technicznymi. Skomentowano przykłady konserwacji tynków, dekoracji malarskich oraz sgraffit wykonanych w ciągu ostatnich sześciu lat. Krytycznej ocenie poddano decyzje dotyczące estetycznych rozwiązań. Omówiono też niektóre zabiegi techniczne np. kładzenie na elewację barwionych w masie tynków. Celem analizy jest zaproponowanie rozwiązań, które pozwolą na zachowanie wartości dawności i autentyzmu wystrojów kamienic Starego i Nowego Miasta.
In recent years, the tenement houses of the Old and New Town in central Warsaw have been undergoing renovation. Does this work fall within the concept of conservation-restoration, or merely renovation? The aesthetic effect is questioned-giving the facades a fresh new appearance. The need to maintain the authentic artistic expression of the decorations of the Old and New Towns is necessary as they are works of outstanding Polish artists. In addition, the Old Town is inscribed on the UNESCO World Heritage List. This paper focuses on the aesthetic and artistic solutions that are closely related to technical measures. Examples of the conservation of plasters, painting decorations and sgraffito that has been undertaken in the last six years are commented on. Decisions regarding aesthetic solutions are critically assessed. Some technical procedures were also discussed, e.g., the application of colored plaster on the facade. The aim of the analysis is to propose solutions that will allow the preservation of the age-values and the authenticity of the exterior decorations of the Old and New Town houses.

Opis:
This paper is devoted to the development of nano-modified cementing composites in the field of self-cleaning building materials. Particle-size distributions of the main constituents such as ultra-fine zeolite and limestone of multicomponent cements, and titanium dioxide and kaolin additives are given. The degree of the interphase of the active surface in Portland cement and supplementary cementitious materials is calculated. It has been shown that due to the synergistic effect, anatase and rutile mixtures can be included in cementing composites to improve the properties of self-cleaning plasters. The influence of titanium dioxide and kaolin additives on the mechanical properties of nano-modified multicomponent cement was investigated using the method of mathematical planning for the experiment. The results obtained using the XRD and SEM methods showed that the addition of high-surface-area nano-scale particles of TiO2 to the cement paste leads to the formation of a denser microstructure in the cementing matrix.

Opis:
Moisture in conjunction with salts can cause significant injury to construction materials. Highly porous and vapour-permeable restoration plasters are used in order to protect walls against moist due to capillary wicking and hygroscopic absorption of water, which are exposed to the harmful effects of salts. The structure of such plasters reduces the capillary conductivity inside the material. The purpose of research was to estimate physical properties of modified plaster mortars. Examination was focused on the impact of the addition of perlite, silica fume and air-entraining admixture on the following parameters: density, tensile strength, compressive strength, strength ratio, capillary absorption of water and water penetration. The microstructure of each material was examined using a scanning electron microscope.

Opis:
The communiqué deals with the problems enceuntered in conservation of plaster in the ground floor section o f the Town Hall in Poznań. As a result of the action o f external factors and, also, o f the lack o f vertical and horizontal insulation in the ground floor section o f the edifice, its plaster there was most decayed and the dirtied. In view o f the necessary partial drying o f the wall, the method of a certain infiltration o f humidity in wall bearings has been applied as the most appropriate one. A project has been worked out for application of the so-called spacing plaster spread from the bottom part of the Town Hall up to the curstable. The insulation space thus created was meant to cut the layer of plaster from spotscaused by humidity in the wall and eliminate the so-called bridges conveying moisture. The author describes in greater detail the process of preparation of „distance plaster” which consists, roughly speaking, in the respective layers of plasters (of which one mixed with bristle) being applied on a suspended lath spread on an adequately designed supporting construction. As a result o f this proceeding an air space of 2—3 cm was created between the wall of the Town Hall and its plaster. The method of application o f spacing plaster has made it possible to attain both the intended conservation, technical and aesthetic objectives. It was on this route, too, that — without any radical change in humidity conditions persisting in its walls for centuries past — the ground floor part of Poznan Town Hall has been protected from the spots and efflorescence marring its beauty.

Opis:
Long reverberation times are a problem in modern churches. General methods of solving the problem are given in the literature. The basic approach is to increase the acoustic absorption of the church, and this can be achieved by placing sound-absorbing materials on the walls. Due to the price, materials with a high absorption coefficient are not used. They are replaced with sound-absorbing plasters. For the known coefficient of sound absorption by plaster, the problem is to calculate the surface of the plaster coverage and its distribution on the surface. This problem was solved for the Academic Church in Rzeszow, the Roman Catholic Parish of St. Jadwiga Queen. The reverberation time before adaptation is equal to 6.78 s, while the predicted time after adaptation is 1.98 s.

Opis:
W artykule przedstawiono wyniki badań starzeniowych wybranych tynków pocienionych w warunkach symulowanych. W celu określenia zachodzących zmian, oznaczano w odstępach czasowych co 100 cykli strukturę porowatości oraz jakościowy skład mineralogiczny metodą dyfraktometrii rentgenowskiej. Wyniki wykazały różnice w poszczególnych fazach starzeniowychdla poszczegól- nych tynków. Wyraźne różnice wystąpiły także w strefach styków termoizolacji i poza ich obrębem.
In below paper results of ageing tests on sofie thinlayer plasters in simulate environrnent are presented. To find changes of plasters during ageing, two physical properties were exafiined in tifie per 100 cycles. One property is pore structure studied by mercury intrusion method and second one is mineral composition analysed by rentgenography method. Effects have shown differences in pore and mineral structure of plasters after successive ageing phases. Distinct differences of examined properties appeared in plaster zones over thermoinsulation gaps and beyond them.
