Abstract
The paper evaluates concretes made with several types of recycled demolition aggregates, focusing on pore structure and sound absorption. Although recycled aggregates generally lower mechanical strength due to higher porosity, that same porosity can significantly enhance acoustic absorption. Using an image-analysis methodology (novel in this context) alongside density and acoustic measurements, the study shows recycled-aggregate concretes can match or outperform conventional concretes in sound absorption, offering an environmentally beneficial alternative for noise-mitigating elements.
