A caricaturistic portrait of Ovid from Brigetio (Komárom/Szőny, Hungary)

AbstractIn 2015 a preventive excavation was carried out preceding the laying of an optical cable in close vicinity to the legionary fortress of Brigetio. An otherwise regular Roman terracotta roof tile was found during the excavation, with the image of a bearded man and the inscribed name of Ovidius Naso. The depiction of the poet leans more towards caricature rather than a realistic portrait, but since we do not know of any ancient representations of Ovid, it is of great importance and fits well into the series of other graffiti on roof tiles from Pannonia.

Exploration of the rules for the use of organic additives in the mortar of the Forbidden city

The Forbidden City exemplifies the official architecture of the Ming (C.E. 1368–1644) and Qing (C.E. 1644–1911) dynasties in China. The buildings within the Forbidden City adhere to a specific construction system and hierarchy. This study examined the organic additives in eighty-three lime mortar samples collected from the Forbidden City. These mortar samples were categorised into two main groups: garden mortar and construction mortar. The construction mortar was further subdivided into masonry, rendering, tile roof, and pointing mortars. Classical chemical analysis was performed to identify organic residues in the samples, including glutinous rice, sugar, oil, blood, and protein. Additionally, ovalbumin, casein, collagen, and peach gum were detected using enzyme-linked immunosorbent assay (ELISA). The results confirmed historical records regarding to the use of organic additives in ancient mortars. Statistical analysis revealed that the organic additives added to different types of mortars were selected according to the location and function of the mortar. This evidence supports the validity of traditional Chinese composite mortar scientifically. Ancient Chinese artisans adhered to rules aimed at practicality and functional realisation when selecting organic additives.

Effect of Resin Content on the Properties of Roofing Tile for Building Materials

The production process of roofing tile materials uses among other materials thermosetting adhesive resins normally urea formaldehyde (UF), phenol formaldehyde (PF), di-isocyanate (PMDI) at various content mixtures, 3wt%, 5wt%, 7wt%, 9w% and 11wt% with a usual thickness of 6 mm. The fibers, adhesives, and other materials are then placed into a steel mold with the standard dimensions of 400 mm x 400 mm, to be then hydraulically pressed at high pressure and the required temperature. Overall, PMDI synthetic adhesives have better physical and mechanical properties than PF synthetic adhesives, however the thermal properties of UF and PF synthetic adhesives are better than PMDI. The physical properties testing were density, humidity content, absorption of water, thickness inflated and water permeability. The mechanical properties such as modulus of rupture (MOR) and modulus of elasticity (MOE), impact strength and tensile strength are all measured according to JIS A 5908-2003, ASTM D 256-2006a,TIS 535-2556 and ASTM D1037-12.The testing for the thermal conductivity, thermal resistivity and solar reflectance were done according to ASTM C177-2010 and ASTM E 891-87. The type of resin content and adhesive used had a significant impact on the physical, mechanical and thermal properties of the roofing tile materials of showed in the results of the analysis of variance (p >0.05). The produced roofing tile has an improved thermal conductivity and heat insulation which can be a substitute for hazardous asbestos based roofing materials.

In this paper, the process of building and transforming the large-scale authoritative buildings of Jeseoksa Temple Site was reviewed by tracing the construction process according to the stages of planning and designing, construction and completion, and reconstruction after disposal. In the planning and design stage, the location of the temple was selected, and the lay-out and size of the temple was determined. Through topographic analysis and survey data review, it was found that the Jeseoksa Temple Site was located in the most optimal location, considering environmental conditions such as flooding and future spatial expandability. In addition, it was estimated that the temple had been built as part of a large-scale urban planning project in Iksan, based on the accessibility and spatial arrangement of the remains of the Wanggung-ri Site. It was understood that the temple layout reflected the aspect of maintaining the ‘one pagoda and one golden hall’ tradition and changes accompanying the expansion of scale. At the beginning of construction, areas of high ground were cut down and soil was piled up at areas of low ground in order to flatten the land; this was likely done in order to secure a wide and solid land plot. Subsequently, in order to build solid foundations for the individual buildings, plate construction was carried out above ground or underground. Finally, roof tiles and walls were utilized to form a temple landscape. In this way, the stage at which the landscape of the entire temple was finalized can be seen as the point of com-pletion. It is estimated that the temple layout featured in a wooden pagoda, golden hall, and auditorium surrounded by a middle gate, corridors, east-west buildings, and monastic buildings. Jeseoksa Temple Site was destroyed by fire in 639, and the temple was subsequently abandoned. After the waste was removed to the Jeseoksa Temple Site waste site, the re-construction stage began. It is estimated that the landscape of the rebuilt temple was trans-formed, with the use of new styles such as convex roof-end tiles with lotus design, con-cave roof-end tiles with arabesque design, and dtamped roof-tiles.

Sustainable Concrete Roof Tiles: Integrating Aluminium Foil, Fly Ash, Solar PV, and Management

This research investigates the use of municipal solid waste cremated fly ash as a viable substitute for natural sand in building methodologies, with a focus on sustainability. The waste material is used in the manufacturing of concrete roof tiles that are combined with solar PV systems, providing advantages in terms of both thermal comfort and improved energy efficiency. These tiles exhibit thermal insulation prowess by effectively preserving a 2-degree temperature differential and collecting heat from solar panels to enhance their energy-production efficiency. In order to enhance performance even further, aluminium foil is strategically placed on all four sides of the roof walls. The foil acts as a reflector, redirecting solar energy towards the tiles, which leads to a 5% boost in power generation. Particular alignments, such as positioning in an east-west or north-south direction, result in further enhancements in performance of 4% and 3%, respectively. This comprehensive approach not only confirms the use of waste materials for environmentally friendly construction but also emphasizes their crucial role in promoting energy-efficient building methods.

Feasibility of foam concrete using recycled brick and roof tile fine aggregates

Brick (BR) and roof tile (RT) fine aggregate fractions derived from construction and demolition wastes have a low recycling rate in new construction and building materials. This article assesses their suitability for replacing the limestone aggregate in foam concrete, which helps valorise such fractions and conserve natural limestone resources. Two concrete categories containing or not silica fume (SF) were investigated, while the BR and RT aggregate replacement rates were 10%, 20% and 40%. Tested properties include flow, density, water absorption, porosity, thermal conductivity, mechanical strengths, microscopy, drying shrinkage, resistance to freeze/thaw cycles and elevated temperature. Results showed that the concrete mechanical properties improved when the limestone aggregate was replaced by 10% BR or RT but gradually curtailed at higher addition rates. Such results concorded with the density, water absorption and porosity measurements. Foamed concrete containing BR is more resistant (compared to RT) to drying shrinkage, freeze/thaw cycle, and heat exposure, which was ascribed to the relatively lower BR porosity that improves the concrete mechanical properties and durability.

Innovative silica aerogel fiberglass walls and roofs: A path to lower carbon emissions and higher energy savings

ABSTRACT Buildings account for a significant portion of global energy use and consumption. Buildings have substantial energy consumption due to the use of heating, ventilation, and cooling systems. It is evident that the insulation materials used in the design of building envelopes can efficiently reduce the cost of air conditioning by reducing external heat gains and losses. Additionally, the use of environmentally friendly and cost-effective can be beneficial from an environmental standpoint. This paper aims to evaluate the potential for cost savings in the air conditioning of buildings incorporated with silica aerogel fiberglass insulation in hollow concrete bricks (wall) and hollow roof tile (roof). Silica aerogel fiberglass insulation is extensively used for heat insulation purposes, including building insulations, due to its superior thermal insulation and flame retardant properties. The thermo-physical properties of silica fiberglass insulation and building materials were determined experimentally as per ASTM D 5334 standards. Twenty distinct building design concepts are investigated in this study, each featuring insulation-integrated concrete blocks composed of silica aerogel fiberglass: (WEM1) insulation layer in the outer side, (WEM2) insulation layer in the center, (WEM3) insulation layer in the inner side, (WEM4) insulation layers in the outer-middle, (WEM5) insulation layers in the middle-inner, and (WEM6) insulation layers in the outer-inner sides. Additionally, two arrangements of insulation-stuffed roof tiles, REM1 above the RCC and REM2 below the RCC. In addition, novel building designs integrated with insulation were analyzed numerically, related to environmental conditions that refer to two different scenarios in India (hot dry and composite climates). Thermo-economic analysis of novel wall and roof designs with silica fiberglass insulation materials on air-conditioning costs, carbon dioxide emissions, and payback time are compared with conventional roof and wall patterns. The thermo-economic analysis was carried out based on the number of degree-hours of heating and cooling to determine the building’s annual energy usage. The building model arrangement (WEM6-REM1), which consists of an insulation composite wall (WEM6) and insulation roof tile (REM1), demonstrated the greatest annual air conditioning cost savings of 3.4 $/m2/year and 1.74 $/m2/year when compared to conventional building design for climatic conditions of Kurnool and Gauhati. The building model arrangement (WEM6-REM1) composed of silica fiberglass aerogel insulation exhibits the highest reduction in carbon emissions of 65 kg/kWh and 33 kg/kWh, when compared to conventional building design analyzed in both hot-arid; (Kurnool) and composite (Gauhati) climatic conditions. The placement of insulation in the roof alone (REM1) has the shortest payback duration of 2.15 years. The results of this study point to a viable approach to enhancing building design decision-making and narrowing the performance gap in sustainable and energy-efficient strategies.

Sustainable building envelopes: Evaluating the thermal performance of thatched roofs fabricated using coconut leaves

Excessive heat gain in residential buildings during sunny days, especially in tropical regions, leads to increased reliance on active energy cooling systems, contributing to higher carbon emissions and energy costs. Traditional roofing materials, such as terracotta tiles are often insufficient in mitigating indoor temperature rise, necessitating the exploration of alternative, sustainable solutions. This study investigates the thermal performance of naturally available coconut leaves used as thatch roofing, comparing it with conventional terracotta tiles, to determine their effectiveness in controlling interior temperatures and reducing heat gain in buildings. To mitigate such a problem, the Near Infra-Red (NIR) light reflectivity of dried plant leaves derived from deciduous and coniferous trees was measured. The structural hierarchy of the leaves was confirmed through Field Emission Scanning Electron Microscope (FESEM), Fourier Transform Infrared Spectroscope (FTIR) and X-ray Diffraction (XRD) studies. FTIR spectra reveal characteristic vibrations of ester, cellulosic components, etc., and XRD confirms the amorphous status of cellulosic materials present in the plant biomass. To study the use of thatched roofs made using coconut leaves as a roofing element, two test huts were fabricated - one was covered using terracotta roof tiles and the other was covered using coconut leaves thatches. The thermal performances of two roofing materials were recorded on a sunny day and the results were compared. The temperature data noticed reveal the fact that the maximum average surface temperature of the terracotta roof model was 59.53 °C, while the rooftop covered with coconut thatches exhibits a temperature of 54.26 °C which is 8.8% less than the hut covered with terracotta tiles. The interior temperature recorded in the coconut thatch was 33.36 °C, which was 1.15 °C lower (34.51 °C) than the terracotta tiles-covered test hut, confirming the better thermal comfortability of thatched roof model than a terracotta roof model.

Physical and Geochemical Characterisation of Pongo Pitti and Bossambo Farm Clays (Littoral Region, Cameroon) for use in Ceramics

The main objective of this work is to discern the physico-chemical and mechanical behavior of the Pongo Pitti and Bossambo Farm clay formations, located on either side of the Sanaga river in the littoral region of Cameroon. To achieve this, two field campaigns and laboratory works were carried out. Four clay materials were collected and brought back to the laboratory. The laboratory investigations involved physico-mechanical and geochemical analyses, followed by ceramic testing. The materials studied have a clayey texture, with clay percentages ranging from 26.89% to 80.3%, silt from 13.2% to 57.6% and sand from 1.58% to 47.26%. The plasticity index ranges from 11.9% to 24.2%. From a geochemical standpoint, the materials studied show a predominance of silica (49.6% to 63.5%), alumina (20.5% to 27.1%) and iron (2.39% to 8.6%), with the SiO2/Al2O3 ratio varying from 1.96 to 3.1. The Al2O3/Fe2O3 ratio is 8.4 for Pongo Pitti clays and 2.9 for Bossambo Farm clays. The geochemical weathering indices (ICV, CIA, PIA, CIW, CIW) show a high degree of weathering, with values in excess of 90%. Alkali and alkaline-earth proportions are lower, and the K2O/Na2O ratio varies between 8.45 and 14.24, showing an enrichment of potassium in relation to sodium. Lantane is the most abundant rare-earth element (323.84 ppm). The REE study shows a predominance of light REEs over heavy REEs (LREE/HREE~4.51) and a negative Europium anomaly. Infrared spectroscopy showed poor kaolinite crystallinity. Mechanically, the specimens studied, fired at temperatures ranging from 950℃ to 1050℃ showed good cohesion and metallic soundness. Linear shrinkage was 4.8%. Mass loss increases with temperature. Its value is 12.5% for Pongo Pitti materials and 8.5% for Bossambo Farm materials. Water absorption decreases with temperature and is 20.27% for Pongo Pitti samples and 15.79% for Bossambo Farm samples. Bulk density increases with temperature (2.11 at 950℃ to 2.51 at 1050℃). Flexural strength increases with temperature and is 6.66 MPa for materials from Pongo Pitti and 8.89 MPa for those from Bossambo Farm. These materials can be used to make fired bricks and roof tiles, and Pongo Pitti materials can be used to make refractory ceramics

Tiebas Castle’ tuiles vernissées: Characterization, raw clay provenance, and manufacturing technology

Tiebas Castle was built between 1254 and 1264 as a royal residence of the kings of Navarre. The Castle was decorated with architectural luxuries imported from the French court. Some decorative elements of this French style are the polychrome roof tiles, called tuiles vernissées; and the glazed floor tiles, called carreaux de pavement. Both are the unique that have been found in the Iberian Peninsula. Elemental and mineralogical analysis allowed us to distinguish two different types of pastes that were used for both tuiles vernissées and carreaux de pavement: yellowish and reddish. The reddish paste was composed mainly of quartz, and to a lesser extent of haematite and illite. The yellow pastes were very rich in calcite and other calcium-bearing minerals (gehlenite, anorthite, diopside or wollastonite) and poorer in quartz and haematite. The different colour tones of the yellow paste samples allowed them to be classified into five subgroups (YP-1, YP-2, YP-3, YP-4, and YP-5). This classification turned out to coincide with a somewhat different mineral composition. The study of the mineral phases newly formed (gehlenite, anorthite, diopside and wollastonite) or destroyed (illite) during firing allowed us to estimate the maximum firing temperature of each of the subgroups. The temperature ranges for each subgroup were as follows: 750–800 °C (YP-5), 850–900 °C (YP-4), 900–925 °C (YP-3), 925–950 °C (YP-2), and 950–1000 °C (YP-1). The study of its possible raw materials allowed us to identify that the yellow pastes from tuiles vernissées and carreaux de pavement were prepared from a mixture of two clays. One of them was the decalcification clay (A15 clay) with which they also made the reddish pastes. The other component of the mixture was the marl from Castle hill. The proportion that the artisans used of both raw materials was 1:2 (twice as much marl as decalcification clay).

삼국~통일신라시대 瓦棺墓에 대한 新고찰

Humanity chose ‘a tomb’ as the time after life, that is, a space to face death. In other words, a tomb is a space where people spend longer than life, and among them, a tomb made of tile used as a building material can be called a Tile Coffin Tombs. Until now, tiled coffin tombs have not received much attention in academia, but recent research cases are increasing. Accordingly, after conducting a survey on the current status, the size and longitudinal ratio of the tomb, the location and direction of the major axis, type classification and year, and burial products and burial patterns were examined. Through this, it was confirmed that there are not a few differences betweenthe tiled tombs of Baekje and Silla cultures. In addition, we looked at the case of China, where Tile Coffin Tombs was first created, and the social image of the Wei, jin, Northern and Southern dynasties in which Tile Coffin Tombs appeared in Baekje. As a result, it was confirmed that Baekje, which had a close relationship with the Chinese Southern Dynasties, continued to exchange technologies in various fields of society and received Buddhism and temples, half-down draft kiln, and new roof tile production techniques. In the process, it was confirmed that the tiled coffin tomb that was introduced into Baekje was later transmitted to Silla, and that through re-localization, the tiled coffin tomb of the two cultures came to be established in different forms. The nature of burial in tile-coffin tombs, which were originally mainly used as infant graves in China, must also be understood in conjunction with these changes and need to be interpreted from a broad perspective.

FAKTOR YANG BERHUBUNGAN DENGAN KELUHAN NYERI OTOT PADA PEKERJA PEMBUAT GENTENG

The job of making traditional roof tiles is a job that is at risk of experiencing complaints of muscle pain because the work process relies heavily on the intensive use of the body's muscles. Apart from that, there are work activities that cause unergonomic work postures, such as standing for long periods, repetitive bending and twisting movements, as well as the process of lifting and carrying roof tiles for a long time. The aim of this study was to analyze the relationship between risk factors and complaints of muscle pain in roof tile workers at RT 04 RW 04 Dusun Sarip, Karangasem. This research was conducted from February 2023 to April 2023. This research is a quantitative study with a cross sectional design. The population in this study were all workers who met the inclusion and exclusion criteria. The research sample was 61 people. The results showed that gender (p=0.126), body mass index (p=0.111), and smoking habits (p=0.993) had no relationship with complaints of musculoskeletal disorders (MSDs), while age (p=0.001), length of service (p=0.002), Physical workload (p=0.011) and work posture (p=0.000) have a relationship with complaints of musculoskeletal disorders (MSDs). The conclusion of this research is that age, physical workload, and work posture are related to complaints of muscle pain in roof tile workers.

Catalytic Potential of Singgora Roof Tiles in Transesterification for Sustainable Biodiesel

The study centred around the uitilization of Singgora roof tiles as a heterogeneous catalyst in the production of biodiesel via the transesterification process. The motivation behind this choice stems from the non-recyclable nature of Singgora roof tiles and their potential applicability in biodiesel synthesis. To enhance the catalytic properties, zinc oxide (ZnO) is incorporated using the wet impregnation technique during catalyst preparation. The catalyst was characterized by XRF and SEM-EDX. A two-step transesterification method is employed to mitigate the levels of free fatty acid (FFA) in waste cooking oil (WCO). The initial step involves treating the WCO with sulfuric acid (H2SO4) to reduce FFA. Subsequently, the Singgora roof tiles catalyst is utilized in the second step. A high yield of FAMEs, specifically 96.96%, was achieved under the optimal conditions, which included a methanol-to- oil ratio of 12:1, a catalyst concentration of 1 wt.%, a reaction temperature of 65 °C, and a reaction time of 2 hours. The quality of the biodiesel produced was analyzed according to biodiesel standards such as ASTM D6751, EN 14214, and AOCS, and it met all the required standards. The study demonstrates the potential of using Singgora roof tiles as a heterogeneous catalyst in biodiesel production, offering a promising approach to repurposing non-recyclable materials and advancing sustainable biodiesel production methods.

Maintenance Approaches Using 3D Scanning Point Cloud Visualization, and BIM+ Data Management: A Case Study of Dahei Mountain Buildings

This study investigates the utilization of 3D laser scanning, GPS, BIM and GIS technologies for safeguarding historical wooden structures. As a case study, it focuses on two historic Chinese wooden buildings, the Guanyin Pavilion and Tangwang Palace, renowned for their exceptional historical significance and intricate timber architecture. The Guanyin Pavilion was subjected to high-precision modeling and tilt monitoring, which found that certain columns had a maximum tilt angle of 0.7892°. Additionally, a general tilt tendency was seen across various structural elements. The measurements from the point cloud data exhibited an error range of ±10 mm. However, the relative errors in smaller components approached 2.5%, which necessitated regular verification through human measurements. Using GIS and BIM technology in Tangwang Palace facilitated the meticulous documentation and dynamic supervision of architectural components, encompassing historical development and present state. The maintenance records revealed persistent problems with the roof tiles and wooden beams, exposing structural vulnerabilities. During various maintenance intervals, it was observed that the roof tiles were frequently loose and separated, indicating potential flaws in the design or materials used. The application of these modern technologies enhances the effectiveness and precision of conservation efforts and provides a robust scientific foundation for the continuous monitoring and study of cultural heritage.

Tile roof inspired structure optimization on radial wood to fabricate oil-water separation function

Cross wood was usually selected to fabricate oil-water separation function. However, the cross wood is easy to be deformed after chemical delignification. Therefore, structure optimization via drilling holes on radial wood along with nano Cu(OH)2/CuCl modification overcame the bottleneck defect of dimensional instability, and simultaneously fabricated oil-water separation function. The oil absorption capacity of modified wood increases with the number and depth of drilled holes, reaching a maximum of 3.7 g/g toward dichloromethane. The modified radial wood demonstrated exceptional filtration effectiveness toward dichloromethane/chloroform-water mixtures and exhibited superior photocatalytic degradation capabilities against methylene blue, malachite green, and direct blue 151 dyes. Additionally, the modified radial wood displayed favorable recycle ability for both oil-water separation and photocatalytic degradation. Thus, a facile, cost-effective and environmental friendly strategy proposed in this work has potential to enhance the practical application of wood based oil-water separation materials.

Fabrication of a Concrete Roof Tile by Geopolymerization of Red Clay with Container Glass Wastes

We report the production of concrete roof tiles using a red clay-based geopolymer binder with container glass waste and river sand as a concrete filler. Clear and colored container glass wastes were separately ground to powder and blended with low-grade red clay to achieve a SiO2/Al2O3 ratio of approximately 7.0. The powder blends were converted to geopastes with a solid-to-alkali solution ratio of approximately 0.8 using a 12-molar alkali activator solution containing a mixture of potassium hydroxide and sodium hydroxide. Rheological analysis showed that the geopaste binders with transparent and colored glass powders exhibited high shear thinning behavior. A higher viscosity was observed for the geopaste with colored glass powder due to the presence of colorants. Fine and coarse particles of river sand were prepared and mixed with different ratios of geopaste binder to river sand of 1:2.0, 1:2.5, and 1:3.0, respectively. All geopaste and river sand formulations were poured into acetate molds and heated in a metal chamber at 80 °C for 24 h, then aged at room temperature for 14 d. The highest flexural strength of 2.33 MPa was obtained from the formulation with a 1:2 ratio of geopaste with transparent glass powder and fine sand. The measured strength corresponded to an apparent porosity of 6.30% and a water absorption of 4.50%. The bulk density was approximately 1.16 g/cm³, which is classified as a lightweight material. A prototype geopolymer concrete roof tile was successfully produced with a sorption coefficient of approximately 0.170 mm/min1/2. This measured sorption coefficient and the physical properties indicate that the produced roof tile is a potential building material.
