Abstract

Perlite is a material widely used in the construction industry to enhance insulation performance of materials building. The current study investigates the feasibility of recycling Hammam Boughrara perlite as building material for enhanced thermal and acoustic insulation of concrete. This research investigates all properties affecting the performance of concrete, including durability, tensile strength, and compressive strength, through a range of mechanical, physical, and chemical tests with a mixture ratio involving raw perlite. It highlights the exceptional insulating properties of perlite, its lightness, and its environmentally friendly nature. The methodology used is detailed, along with the research objectives and expected results. Also, this work provides an overview of the knowledge to be gained and helps to better understand the benefits of using perlite in the field of thermal and acoustic insulation of concrete. Thermal treatment of mortar samples took place at various temperatures including 200°C, 400°C, and 600°C, followed by tests including thermal conductivity, ultrasonic pulse velocity, and compressive strength. Confirmed that addition of perlite increased insulation power of concrete yet allowed sufficient integrity for extreme conditions. The importance of this research lies in its contribution to both: the insulation potential of perlite which responds to the needs of the architectural community in modern building activity, and in addition the economic valorization of natural components found in the immediate surroundings. The results illustrate the opportunity for identification of green, energy-efficient, and lightweight building materials designed to meet environmental issues and regional social-economic demands.
