El Colegio Máximo de Cartuja en Granada fue construido por los jesuitas en el siglo XIX. El estudio arqueométrico de sus materiales: ladrillos, azulejos, vidrieras y morteros, define el concepto vernáculo de esta construcción, referenciada en el marco geológico de la “formación Alhambra”, junto a la identificación de materias primas y técnicas utilizadas por los nazaríes desde el siglo XIII. Los resultados de XRD, XRF y DTA confirman el uso de arcillas locales para fabricación de ladrillos y losetas que se hornearon a temperaturas de ≤750 ºC. Las arcillas debieron contener aditivos de NaCl que beneficiaron la sinterización cerámica, y se comprobó el uso de colores de tradición nazarí (Cu, Fe, Sn) en los esmaltes y vidrieras. Las materias primas locales también se usaron para producir aglomerantes aéreos. Estos resultados se han combinado para crear una guía de buenas prácticas para la restauración sostenible de los edificios del patrimonio cultural.

This paper evaluates two types of concrete with hemp fibres as natural aggregates prepared with inorganic binders, based on reactions (Si-Na) and (Si-Ca). It also was tested two states of conservation of the hemp: 1) fresh and 2) preserved in moist conditions for six months. The results indicate that the changes induced by wet preservation, above all the increase in the percentage of cellulose, improve the mechanical properties of the concretes and is equivalent to other pretreatments conducted to improve the conditions of the hemp fibres confirmed by performing compositional, mineralogical and physical studies of the raw materials and the concretes. The dosages used in this study provided high quality concretes in comparison with other studies with similar dosages.

This paper presents the study of the most common types of construction flaws in facing brick facades. It is intended to study the intervening parameters and know the interrelations between them, developing a risk evaluation framework through a process of categorisation. The 274 cases analysed correspond to the totality of the period of the study and cover the entirety of the Spanish territory. The adaptation of the weighted factor method allows to establish and quantify risk categories according to the number of variants of interrelations and according to the number of cases, subsequently determining the risk of lawsuit for each construction flaw. The results include a dual study according to the two above-mentioned concepts, providing a standardised codification of each case, as well as its individual risk factor. As for the evaluation, five risk categories are established (very high, high, moderate, low and very low), allowing to demonstrate that, by intervening on certain interrelations (whether in the design stage or in the execution stage) it is possible to clearly reduce the probability of litigation, as well as the number of associated construction flaws. Consequently, the establishment of the aforementioned categories constitutes a very useful tool for risk managers – requiring first their identification and, secondly, their control and reduction.

The cemetery of Jesus of Murcia (Spain) has more than 600 pantheons, which converts it in a small funerary city, whose buildings show a large spectrum of architectural samples. This paper presents an exhaustive study of the typologies and materials used in those little buildings. In addition, this investigation addresses the study of the evolution and the distribution of the typologies and materials detected, drawing conclusions about both of these aspects.

To improve the energy performance of restored cultural heritage buildings, it is necessary to know the real values of thermal conductivity of its envelope, mainly of the facades, and to study an intervention strategy that does not interfere with the preservation of their cultural and architectural values. The brick walls with which a large number of these buildings were constructed, usually absorb water, leading to their deterioration, whereas the heat transmission through them is much higher (than when they are dry). This aspect is often not taken into account when making interventions to improve the energy efficiency of these buildings, which makes them ineffective. This article presents the results of an investigation that analyzes thermal behavior buildings of the early 20th century in the city of Zamora, Spain. It has been concluded that avoiding moisture in brick walls not only prevents its deterioration but represents a significant energy saving, especially in buildings that have porous brick masonry walls and with significant thicknesses.

New energy-efficient materials are increasingly used in architecture and civil engineering today. Many of these are based on the reuse of plants and plant residues from industry and agriculture for the production of bio-sustainable insulation materials, and as aggregates in concretes. This paper presents the results of our study of research into hemp concrete, an emerging material in the green building sector, since it first appeared about twenty-five years ago to the present day. The study centres on a growing bibliography over this period, emphasizing some fundamental parameters of hemp raw materials and related building materials, the binders used in the production of hemp aggregate concretes and assessments of different aspects of their performance. The most important properties of hemp concrete vary according to the quality of the plant aggregates, the choice of binders (typically aerial or hydraulic lime), the proportions of the raw materials and the application techniques. Organic aggregates are less stable than inorganic aggregates and are therefore more difficult to use in a concrete mix with both inorganic and organic binders. Among other reasons, this is due to the disproportionate amount of water required in the mixing of plant-based concretes and to the release of organic compounds, which can have serious effects on the hardening process. This problem was identified in scientific studies on the use of hemp concrete in sustainable, bioclimatic construction, whether applied as a semi-liquid mass or as a precast element. This new biomaterial offers excellent results in terms of its application on site and has important physical properties, such as high durability and easy conservation. This study seeks to provide a useful tool for future research into sustainable building materials, better use of available energy and plant-based resources and more efficient recycling of the waste produced by human activities.

This paper examines the most common deficiencies in construction units outside buildings, along with their relationship with climatological factors, through the analysis of three hundred cases. The knowledge of construction problems helps prevent the re-occurrence of errors, thus improving the sustainability of buildings and their infrastructure. Methodologies for determining the prevalence of errors enable the identification of critically affected zones associated to climatological factors (rainfall, latitude and climate). The various underlying causes (11 in total) were also evaluated, along with the construction units that most frequently experienced the deficiencies. The deficiencies were grouped into 9 different types, and the origin of the error was ascertained for each case. The study concluded that the most frequent deficiencies were ‘detachment’ and ‘ground subsidence’ and that the most critical areas were certain ‘strips of climatological location’ situated at once in a northern latitude and close to the sea. This yields important information for construction engineering, given that the determination of the most frequent deficiencies and of their causes allows them to be addressed in the design and execution stages, ensuring an effective management of the construction process.

The cogency of evaluation models able to predict future trends and to monitor the consequences of scenarios different from those initially expected has been determining a growing scientific interest for the development of financial sustainability methods. With reference to quarterly time series collected for the metropolitan area of five Spanish cities, in this research an innovative methodology has been implemented, in order to make explicit, for each case study, the main functional relationships between the housing prices and the socio-economic factors. The models obtained are characterized by both high statistical performance and compliance with the expected market phenomena, highlighting the decisive role in the housing price formation of the factors that indirectly represent the population’s income capacity (market rents, unemployment level, mortgages). Then, an empirical procedure for the construction of the future property value trends has been developed. The results point out the forecasting and monitoring potentialities of the methodology used, as a fundamental decision support tool in the urban planning policies of the local administrations, interested in anticipating and checking future housing bubbles through appropriate economic policies, and for private operators, in the phases of selection of the most attractive territorial areas for new property realizations.

The objective of this paper is to examine the influence of the deterioration of the stone material in the structural capacity of the tomb of Khunes at Qubbet el-Hawa, through the evaluation of its static structural behaviour in the face of an earthquake. For this, two different cases are examined, the first is to evaluate the model corresponding to the ideal theoretical state of the tomb and the second is to make another model that considers the internal fractures of the rock in which the hypogeum was excavated. The calculation is made up of a static analysis that evaluates the stability of the whole, and a dynamic analysis of our results that estimates the tension distribution, displacements and deformations that might occur under the influence of an earthquake with particular characteristics of the area. The results provide accurate information on two issues: the behaviour of the stability of the tomb that is expected in the current state and given its mechanical behaviour; the response to an earthquake in view of the special characteristics of the geographical location.

Interventions in historic brick buildings require an exhaustive analysis of the current characteristics of bricks in order to establish the role performed by these elements in the buildings. This study presents the results of an experimental analysis of the compressive strength of brick specimens extracted from different buildings built in the 19th and 20th centuries in the province of Zamora (Spain). The study analyses specimens with very different characteristics to compare results from different masonry units and manufacturing processes. Specimens are classified into four groups according to their macroscopic and microscopic analyses. Compressive strength results are correlated to the above classification and to the results of density, absorption and open porosity of the samples. The compressive strength results present high variation between clay bricks (9.2–64.4 N/mm2) and between samples extracted from the same brick due to the heterogeneity of the material. Correlations between compressive strength and open porosity, absorption and dry density values are observed, with less dispersion in the case of high sintering level, up to 1000 °C. Finally, the compliance with the current Spanish Technical Building Code with respect to their compressive strength is checked.

Many architectural constructions with heritage value around Lake Tana (Ethiopia) were erected by the Jesuits in the 17th century, who used techniques and materials from the classical Roman tradition. The study of its state of conservation and their building materials (masonry concrete, masonry mortar, painted plaster, masonry bricks, and masonry stone) has revealed the great constructive technique and the high quality of binders used by them. Various samples from each monument were taken and subjected to chemical analysis (FRX), X-ray diffraction tests, polarized light optical microscopy, scanning electron microscopy, ultrasounds, and colorimetry tests. The composition results provided important information about the provenance of the materials used by the Jesuits. Their air lime binders were also of particular interest due to the addition of locally sourced diatomite earths to create a product with high mechanical resistance and durability. The techniques introduced by the Jesuits can be used today in the sustainable, economical restoration of heritage in Ethiopia and adjacent regions.

There are numerous parameters which define the mechanical properties of hemp concretes. Several authors identified significant differences in mechanical properties due to the quality, particle size, form and distribution of the hemp aggregates, and also due to the energy of compaction, binder dosage, density, drying conditions and drying time. The other factors which influence the mechanical properties of hemp concretes are the type of binders and their influence on the setting process of mortars containing plant aggregates. This research work has been done to encourage the use of hemp in construction industries that can reduce the usage of industrial binders and shift the focus on natural binders. The experiments were carried out to observe the drying kinetics, capillary water uptake and mechanical strength of hemp-clay concretes made with de-fibered or non-de-fibered hemp materials of industrial and domestic origin. The influence of addition of the lime on the mechanical performance of hemp-clay composites was also studied.

Resumen La realización de estudios sobre el estado de conservación previo a las intervenciones rehabilitadoras y restauradoras permite conocer y actuar de forma coherente sobre el patrimonio arquitectónico. En esta línea se ha llevado a cabo la investigación de localización gráfica de alteraciones, estudio puntual de materiales de alteración y medición de parámetros ambientales (T y H) en las yeserías del Oratorio de la Madraza de Granada, espacio singular por sus antecedentes históricos y constructivos. Los resultados obtenidos determinan el nivel de alteración y presencia de los diferentes deterioros, así como la justificación de las causas de alteración que los han motivado. Igualmente se valida la metodología seguida en este estudio, consistente en diversos protocolos sucesivos que facilitan la determinación de las intervenciones restauradoras. De igual manera este método puede ser extrapolable a otros edificios con alto nivel de protección patrimonial.

By using the non-destructive technique of ultrasonic transmission, this paper undertakes a study of the compositional and structural discontinuities in marble from Macael (Almería, Spain), which is the material of the columns in the Court of the Lions in the Alhambra (Granada, Spain), in order to contribute to understanding of the processes of deterioration and conservation affecting them. Thermal stress is responsible for alterations in the columns, and is affected by scaling, loss of substance, stains, etc. The results allow us to establish that, apart from the discontinuities in the mineralogical composition of the marble, the preferential orientation of the calcite crystals has an important effect on its anisotropic reaction. This preferential orientation is confirmed by textural studies using X-ray diffraction and determinations using a petrographic microscope equipped with universal stage.
