“…Results show that the use of expanded cork granules decreases density, compressive strength and thermal conductivity of the screeds while increasing their water vapor permeability. The thermal delay of the concrete floors with layers of cork was analyzed [ 39 ]. The potential of these composites in applications for increasing the thermal performance was shown.…”

This review work is an update of a previous work reporting the new cork based materials and new applications of cork based materials. Cork is a material which has been used for multiple applications. The most known uses of cork are in stoppers (natural and agglomerated cork) for alcoholic beverages, classic floor covering with composite cork tiles (made by the binding of cork particles with different binders), and thermal/acoustic/vibration insulation with expanded corkboard in buildings and some other industrial fields. Many recent developments have been made leading to new cork based materials. Most of these newly developed cork materials are not yet on the market, but they represent new possibilities for engineers, architects, designers and other professionals which must be known and considered, potentially leading to their industrialization. This paper is a review covering the last five years of innovative cork materials and applications also mentioning previous work not reported before.

“…Increasing amounts of solid waste are produced, placing constraints on the availability of landfill sites, with a consequent rise in disposal and dumping costs (4). The current research examines the viability of introducing various wastes of industrial origin in a gypsum matrix (5)(6)(7)(8). The aim is to reduce the weight of the gypsum and to improve its thermal properties.…”

Gypsum plasterboard that incorporates various combinations of polyurethane foam waste and polypropylene fibers in its matrix is studied. The prefabricated material was characterized in a series of standardized tests: bulk density, maximum breaking load under flexion stress, total water absorption, surface hardness, thermal properties, and reaction to fire performance. Polypropylene fibers were added to the polyurethane gypsum composites to improve the mechanical behavior of the plasterboard under loading. The results indicate that increased quantities of polymer waste led to significant reductions in the weight/surface ratio, the mechanical strength and the surface hardness of the gypsum, as well as improving its thermal resistance. The polypropylene fibers showed good adhesion to the polymer and the gypsum matrix, which enhanced the mechanical performance and the absorption capacity of these compounds. The non-combustibility test demonstrated the potential of the new material for use in internal linings. RESUMEN: Caracterización de placas de yeso con residuos de espuma de poliuretano reforzadas con fibras de polipropileno.Este artículo presenta un estudio experimental basado en la reutilización de residuos de poliuretano en una matriz de yeso para elaborar una placa de yeso laminado. Las placas fueron caracterizadas mediante los ensayos normalizados de densidad aparente, carga de rotura máxima a flexión, absorción total de agua, dureza superficial y reacción al fuego. Se han introducido fibras de polipropileno en la matriz con el objetivo de aumentar la resistencia mecánica del material. Los resultados muestran que el incremento de residuo polimérico en el material implica importantes reducciones de peso, resistencia mecánica y dureza superficial, a la par que se mejora su resistencia térmica consiguiéndose valores similares a los comerciales. Las fibras de polipropileno mostraron una buena adhesión con el polímero, mejorando el comportamiento mecánico y la capacidad de absorción. El ensayo de reacción al fuego confirmó que los residuos de poliuretano pueden ser empleados en la fabricación de placas de yeso laminado en cumplimiento con la normativa.

“…However, the starting time of increasing energy consumption shifted slightly from the starting time of increasing surface temperatures. This disparity is owing to the temperature delay caused by the heat capacity of insulation materials (Tadeu et al, 2014). Refrigerated containers at the top tier have higher ranges of energy consumption, with an average consumption of about 7.7 kW, followed by the bottom and middle tier, which have an average consumption of about 7.5 kW and 7.4. kW, respectively.…”

This paper investigates the stack effect on the power consumption of refrigerated containers. The investigation is based on measurement experimentation that was conducted in Hakata Island City Container Terminal, Fukuoka, Japan. Experimentation was carried out over summer 2015, using three stacks of high cube refrigerated containers. Several sensors and devices were employed to ascertain parameters, including pyranometers, thermocouples, and power analyzers. Five units of pyranometers were set on a horizontal and vertical plane, facing all cardinal directions. Thermocouples were installed inside and outside of walls at a total of twenty points. Power meters employed to measure energy consumption were set on the power plug station nearby the measurement object. Measurement results showed that the stacking position of refrigerated containers affects the distribution of surface temperatures and power consumption. The average surface temperatures obtained on the top tier, middle tier, and bottom tier were 45°C, 41°C and 38°C at noon, respectively. Consequently, the average power consumption from the top tier, middle tier, and bottom tier were shown as 7.7 kW, 7.4 kW and 7.5 kW, respectively. From these results it can be concluded that the stacking effect of containers provides thermal benefit to the power consumption of refrigerated containers that are located on the middle tier and bottom tier.
