Once the tide recedes and leaves a significant amount of stranded seaweed on coast, marine macroalgae pose serious threat to surrounding area. Through this work, we considered large-scale application in building construction. For first time studied impact incorporating Sargassum mitucum fiber replacement flax used for standard structural cob. Thus, cob specimens were elaborated analyzed evaluate their compressive hygrothermal performances. It was found that strength water vapor resistance...
Building construction is a major polluting sector. As result, there increasing global interest in the development of sustainable building materials with low environmental impact. Earth-based are among and earth-based has thus received particular renewal attention. Previous research focused on physical characteristics durability these materials. The aim this study to assess variability made in-situ their reproducibility laboratory using an automatic normal Proctor machine different compaction...
The population of developed nations spends a significant amount time indoors, and the implications poor indoor air quality (IAQ) on human health are substantial. Many premature deaths attributed to exposure pollutants result from diseases exacerbated by air. CO2, one these pollutants, is most prevalent often serves as an indicator IAQ. Indoor CO2 concentrations can be significantly higher than outdoor levels due respiration activity. primary objective this research was numerically...
This study focuses on the drying kinetics of cob and light-earth layers comprising a hybrid walling system. Volumetric water content sensors are immersed placed at different positions walls building to measure kinetics. In addition, an experimental analysis effect temperature, relative humidity (RH), wind velocity variations thermal conductivity in climatic chamber under winter summer conditions was conducted. The samples laboratory aims investigate hygrothermal properties materials, their...
This paper investigates the in situ hygrothermal behavior of a cob prototype building equipped with multiple sensors for measuring temperature, relative humidity inside building, and water content within its walls. The experimental results show that earth-based presents interesting thermal insulation performance. Without any heating system, indoor temperature was found to remain stable, near 20 °C, despite large fluctuations outdoor temperature. study also illustrated ability absorb regulate...
The enhancement of figure merit (ZT) thermoelectrics is becoming extremely important for an efficient conversion thermal energy into electrical energy. In this respect, reliable measurements and parameters are paramount importance in order to characterize thermoelectric materials terms their efficiency.
A new and accurate method for the thermal characterization of thermoelectric liquids is proposed. The experiment based on a self-generated voltage due to Seebeck effect. This provided by sample when one its two faces thermally excited using modulated laser. used tetradodecylammonium nitrate salt/1-octanol mixture, with high coefficient. properties (thermal diffusivity, effusivity, conductivity) are found compared those obtained other photothermal techniques. In addition this, study...
Cob is an earthen building material made by soil, fibres and water used for millennia. However, cob construction disappeared out during the nineteenth century. These last years, it experiencing a renaissance in Northwestern France Southern England. Due to limited technical knowledge, investigation of engineering properties important modern design practice code requirements. Moreover, ensure properties, necessary have same quality mix along phases. The aim this study determine variation...
Knowledge of indoor air quality (IAQ) in cob buildings during the first few months following their delivery is vital importance preventing occupants’ health problems. The present research focuses on evaluating IAQ through a prototype built Normandy, France. To achieve this, was equipped with set sensors to monitor various parameters that determine and outdoor quality. These include relative humidity (RH), carbon dioxide (CO2), nitrogen (NO2), ozone (O3), particulate matter (PM1 PM10),...
Mastering construction times is of paramount importance in making vernacular earth techniques attractive to modern clients. The work presented here a contribution towards the optimization time cob buildings. Therefore, this paper follows evolution cob’s mechanical properties during its drying process case double-walling CobBauge system. Laboratory tests and situ measurements were performed, further results described. Volumetric water content sensors immersed walls prototype building...
This work focuses on the photothermoelectric (PTE) technique allowing thermal characterization of solid-state thermoelectric (TE) materials. Previously, this was restricted to TE materials having low electrical conductivities. Here, PTE is extended and generalized all with or high achieved by taking into account Gaussian shape excitation source. The formalism new methodology developed procedure for extracting parameters proposed. For illustration, two different are studied: relatively...
Abstract To reduce building significant contribution to greenhouse gas emissions, architects and engineers are seeking eco-friendly construction solutions. Among investigated options, building’s thermal insulation heat storage can be cited. In this regard, earth-based materials attracting particular interest. These last years, there is a renewed interest in these techniques. This due many advantages that they present: excellent humidity regulation ability high inertia. Present study aims...
