Acoustical and heat characterization of recycled fibre reinforced bricks

Abstract

The present paper reports the acoustical and heat characterization of sheep wool in building units (bricks). In this paper, an attempt is made to rebuild traditional bricks by using wool as a natural admixture to improve heat and sound absorption attributes while also increasing structural strength. Recycling these leftovers creates long lasting building materials while also helping to safeguard the environment. Different specimens of bricks with varying proportions of wool had been prepared and were tested against disparate mechanical properties to highlight the difference between the traditional and adobe (predominantly derived from waste materials) bricks. The processes for specimen preparation and testing are described. Engineers and designers looking for eco- friendly methods should be interested in the utilization of waste materials in the construction sector. It is very crucial to experimentally determine the acoustic properties of building materials due to demand for materials suitable for constructions located in places with high level of noise, typically in urban areas and places close to the areas with heavy traffic researchers who are working to create methodical techniques to assessing, regulating, and analyzing the performance of waste material additives will find it useful. With the increase in quantity of wool, increase in density was observed. The 3.2WB specimen with 3.2% wool had a maximum compressive strength of 70 N/mm2. The property of water absorption gave 13.86% as minimum value of 1WB brick with 1% wool in it. When it comes down to initial rate of absorption of these kind of fiber bricks, it lies between 0.25 to 1.5 kg/m2/min. It drops around 15% of noise coming inside the room. Last, the conclusion part of this review gives an outlook regarding the utilization of the wool fiber by means of theoretical study, efficient and environmentally friendly experiments.
