摘要
研究了掺入聚合物对高性能轻骨料混凝土力学性能及微观结构的影响。结果表明,掺入聚合物可以显著提高高性能轻骨料混凝土的抗拉强度和抗折强度,具有很好的增韧效果,韧度系数最高可提高32.2倍。同时,借助SEM观察了界面过渡区的微观结构,从界面微观结构的角度对聚合物改性效果的差别进行了分析。
This paper studies the influences of polymer on the mechanical properties and microstructure of HPLWAC. Results demonstrate the addition of polymer into HPLWAC can increase its tensile strength, flexure strength, and toughness. Toughness index of polymer modifying HPLWAC is 32.2 times of that of plain HPLWAC. Microstructures of interracial transition zones are studied using SEM, and polymer-modifying effects are analyzed from microstructure point.
