Development of Novel Concrete Noise Walls Incorporating Recycled Materials

该项目将开发高性能、轻质混凝土隔音墙和隔音屏障，使用回收轮胎和玻璃产品来改善吸声效果，并解决与开采河沙和储存废轮胎和玻璃产品有关的环境问题。隔音墙技术的创新在于开发低碳混凝土混合料(使用较少的水泥)，最大限度地使用再生产品，同时减少墙体厚度，同时保持必要的工程性能，如声学、强度和耐久性。除了更高的隔音性能外，这种新型的低碳、轻质的面板还将改善材料的处理能力，并提高隔音屏障的价格。

This project will develop high-performance, lightweight, concrete noise walls and acoustic barriers that use recycled tyre and glass products to improve sound absorption, and address environmental problems associated with the mining of river sands, and stockpiling of waste tyre and glass products. Innovation in noise wall technology consists in developing low-carbon concrete mixes (using less cement) with a maximum amount of recycled product, together with reducing wall thickness, while maintaining the necessary engineering properties such as acoustics, strength, and durability. In addition to higher acoustic insulation, the novel low-carbon, lightweight, panels will improve material handling and affordability of noise barriers.
