The purpose of this study is to explore the preferable aging conditions of building facades in the preservation district for historical landscape. We took photos of six buildings which were built in ...the last ten years, and simulated fifteen kinds of aging facades of each building. Next, we conducted the subjective experiment on the evaluation of the building facades. Twenty female participants observed a facade image selected from 96 stimuli randomly, and evaluated it in terms of “oldness”, “unnaturalness”, “calmness”, “familiarity” and “preference”. The results showed that “oldness” is higher as the chroma value of the exterior wall is lower, and that the “oldness” is influenced by the quantity as well as the darkness of the luminance unevenness. In addition, “preference” of the building facade correlates with “calmness” and “familiarity”, and the aging facade of each building has an appropriate “oldness” for “preference”.
ResumenEl propósito principal de este trabajo de investigación se centra en el estudio del estado de conservación de las fachadas de 34 inmuebles pertenecientes al Catálogo de Bienes Inmuebles y ...Elementos Protegidos del Plan General del Ayuntamiento de Cieza (Murcia), concretamente de aquellos situados en el casco urbano, para aportar directrices que garanticen una intervención con materiales sostenibles coherente y respetuosa con el patrimonio arquitectónico de la ciudad. Evidentemente, un desarrollo correcto del estudio diagnóstico constructivo de las fachadas de inmuebles protegidos debe llevarse a cabo en 2 fases: la caracterización constructiva de la arquitectura de sus fachadas y el estudio de lesiones o estado actual que presentan las mismas. Tras analizar los 34 inmuebles se establece una metodología y un modelo sistemático para la documentación del grado de deterioro que presentan las fachadas de los inmuebles del Catálogo de la ciudad. Destacamos que los resultados de materiales propuestos en las fachadas dan unos niveles de deterioro “bajo” o “muy bajo” en el 70 % de los casos analizados, corroborándose el buen estado general de las mismas.AbstractThe main intention of this research work focus interest on the 34 building’s facade from the state of preservation belonging a Municipalities Heritage Catalogue of Cieza's Town (Murcia), it specifically those that located in the urban area from to comply with the guidelines established by sustainable materials coherent and respectful with the architectural heritage of the city. Evidently, a correct development of the diagnostic constructive study of the 34 building’s facade must be carried out in 2 phases: the constructive characterization of the architecture of his building’s facade and the study of the state of conservation or current condition that the same ones present. After analyzing 34 building’s facade methodology and a systematic model it establish for the documentation of a Municipalities Heritage Catalogue of Cieza's Town of the city. We emphasize that the results of proposed materials building’s facade give a few levels of low or very low deterioration in 70 % of the analyzed cases, there being corroborated the good general condition of the same ones.
In modern construction field there is a constant need in new high-performance materials, that's why the manufacturing companies constantly release new high-tech materials on the market. An important ...factor is the cost of construction materials: if earlier construction firms mostly preferred foreign producers, taking into account the significant growth of the European and American currencies rate they increasingly use the domestic producers products today. In the choice of material construction companies have high requirement on the durability, reliability, ease of installation, products cost-effectiveness. Speaking about exposed panels they also have demands to a high resistance to aggressive climatic conditions. The features of such modern construction materials as metal-ceramic panels "Hardwall" by «Bautrade» are examined in this article; and especially we study their advantages over other analogues of this product on the market. The purpose of our study is to confirm the high technical characteristics of the metal-ceramic panels "Hardwall". During the testing according to GOST 18124-2012 methodic we got some results of tests in which we determine the ultimate bending strength at the universal electromechanical machine «Instorn 3382» made for measuring the tensile strength, bending, peeling. These results provide us with a loss strength percent of the metal-ceramic panels. In addition, we made the frost-resistance tests. After the tests, all samples showed a satisfactory value, specified in GOST 18124-2012. And also a comparison of the ultimate bending strength test results of the samples tested for frost-resistance and samples not tested for frost-resistance was made. Thus, the panels have all the necessary properties: they are resistant to aggressive environmental influences, to impact loads and chemical influences. Also, the panels can resist to high temperature differences. Nowadays metal-ceramic panels "Hardwall" are one of the most sought decoration materials, the safety and quality of which are confirmed by a number of laboratory tests.
