This study investigates the development and acoustic performance of a layered composite structure composed plastic microfibre pulp (PMFP) metamaterial (PAM), designed for low-frequency sound wave control. Addressing dual challenge reducing waste enhancing absorption, research explores use recycled materials in innovative applications. PMFP was tested various thicknesses, while PAM resonators were 3D-printed with adjustable neck lengths diameters to achieve optimal absorption characteristics....
The paper analyses the properties (chemical and mineral composition, microstructure, density, etc.) of recycled tannery sludge (TS) possibilities for using it in cement mortar mixture. Mortar specimens containing 3-12% by weight 3-9% sand were tested. Flowability, ultrasonic pulse velocity (UPV), flexural compressive strength, water absorption sorptivity analysed. X-ray diffraction (XRD) scanning electron microscopy (SEM) analysis are presented. tests revealed that replacement 6% with mix...
Since society is moving towards sustainable development, interest in secondary use of waste has recently become significant. This paper investigates a process to develop an acoustic material, using two types waste. Composite panels were developed tyre textile fibres (WTTF) and sludge (PS), polyvinyl acetate (PVA) used as binder. Non-acoustic (bulk density, airflow resistivity) (sound absorption coefficient, sound transmission loss) parameters studied. with different proportions WTTF/PS/PVA...
Clay materials were prepared with clay and sapropel (SP) or modified (frozen) (FSP) as the main raw materials. Clay-based formed by mixing a different dosage of SP FSP (5–30 wt.%). The effect on properties biological resistance clay-based was studied. results show that bulk density decreased, compressive strength initial rate water absorption increased increase in amount mixture. Research has shown can be added natural additive containing microfibers to improve mechanical When bricks had...
