摘 要: 本文详细介绍了掺JSJ减缩剂的砂浆和混凝土性能及初步应用情况。结果表明:JSJ减缩剂能有效降低砂浆和混凝土的干缩,推迟和减少混凝土的开裂,适当提高砂浆和混凝土的强度,以及降低泌水率、提高耐久性等。 This paper entirely introduces performances of mortar and concrete incorporated with JSJ shrinkage reducing admixture and its primary application. Results indicate that the admixture can reduce dry shrinkage effectively, delay or reduce concrete's cracks, improve comprehensive strength, reduce bleeding ratio and enhance durability etc.
