摘要:
随着中国工业副产石膏的日益增加,探索其高值化利用途径已成为当前研究的热点。硫酸钙晶须作为一种具有高强度、高韧性和优异耐高温等特性的材料,逐渐成为利用工业副产石膏的一种重要方式。近年来,利用硫酸钙晶须对沥青改性的研究取得显著进展,表明硫酸钙晶须能显著提高沥青的高温性能、抗车辙能力及耐老化性能;但其在沥青改性过程中引发的低温性能下降问题仍需突破。为解决这些问题,研究者们开始探索将硫酸钙晶须与其他材料(如SBS聚合物、废弃油类)协同使用,或对其进行表面改性,以提高其在沥青中的性能。基于该领域研究进展的系统梳理,介绍硫酸钙晶须的制备方法、基本性质及其在改性沥青中的应用现状,首次系统总结其在沥青改性中的作用机理、改性效果及与其他材料的协同应用。此外,对硫酸钙晶须应用中面临的挑战及未来的研究方向进行展望。硫酸钙晶须作为一种可持续且具经济效益的材料,有望为沥青的改性提供一种新的途径,并推动道路工程的绿色发展。
