The disposal and waste management of solid high energy propellant (HEP) is a considerate conservational problem. HEP waste is currently disposed in open or confined burning which may cause environmental hazards. In this paper, we examined and discussed results on recycling of HEP waste into fired clay bricks baked in different orientation. HEP modified bricks with 1.5%, 3% and 5 wt. % HEP waste content were manufactured and tested, and then compared against virgin clay bricks without HEP content. The effect of directional orientation of bricks baked with varying HEP content on acoustic properties were experimented and discussed. The sound transmission loss decreases with increase in HEP waste due to formation of independently closed directional pores. The transmission loss of horizontally baked during firing of bricks is nearly 5dB lower than vertically baked bricks. Results of the experimental studies indicate that HEP waste can be utilised in fired clay bricks and different orientation baking further enhances the acoustic properties.

“…A phase-change material acts by absorbing and liberating heat instead of concrete, changing its physical state and avoiding damage to its structure, extending both lifespan and performance, as proved by Arivazhagan (4). A PCM can store and liberate heat many times, promoting continuous heating-cooling cycles, as found by Uthaichotirat and collaborators when they studied the behavior of a PCM added to a concrete matrix (5).…”

the objective of this research is to test different variables combinations and show which Poly (cutylene succinate)based (PBS-based) material OBS material has the best properties to be added as a Bio-phage-change material in concrete matrices. In this experimental study, a novel PBS-based phase change material (PCM) was synthesized to be applied in concrete systems to increase thermal resistance. Box-Behnken design was followed to produce a total of 14 samples with different reaction times, catalyst concentrations, and glycerin concentrations (which acted as additives). All of the samples were able to decrease the regular melting point of PBS from 110ºC to around 68ºC, showing a significant improvement that allows the use of this material to improve the thermal properties of concrete systems.

“…Phase change materials have often been used recently as a thermal mass increase method, in order to improve the thermal performance of building shells [26]. However, their effect on the sound insulation capacity has not yet been examined extensively, with relatively few studies dealing with the subject [27,28].…”

Indoor Acoustic Comfort Provided by an Innovative Preconstructed Wall Module: Sound Insulation Performance Analysis

The complicated nature of indoor environmental quality (IEQ) (thermal, visual, acoustic comfort, etc.) dictates a multi-fold approach for desirable IEQ levels to be achieved. The improvement of building shells’ thermal performance, imposed by the constantly revised buildings’ energy performance regulations, does not necessarily guarantee the upgrade of all IEQ-related aspects, such as the construction’s acoustic quality, as most of the commonly used insulation materials are characterized by their low acoustic performance properties. From this perspective the SUstainable PReconstructed Innovative Module (SU.PR.I.M.) research project investigates a new, innovative preconstructed building module with advanced characteristics, which can, among other features, provide a high quality of acoustic performance in the indoor space. The module consists of two reinforced concrete vertical panels, between which the load bearing steel profiles are positioned. In the cavity and at the exterior surface of the panel there is a layer of thermal insulation. For the scope of the analysis, different external finishing surfaces are considered, including cladding with slate and brick, and different cavity insulation materials are examined. The addition of Phase Change Materials (PCM) in different mix proportions in the interior concrete panel is also examined. For the calculation of the sound insulation performance of the building module the INSUL 9.0 software is used. The results were validated through an experimental measurement in the laboratory in order to test the consistency of the values obtained. The results indicate that the examined preconstructed module can cover the sound insulation national regulation’s performance limits, but the implementation of such panels in building constructions should be carefully considered in case of lower frequency noise environments.
