摘　　要：分析比较砂浆尺寸变化率测试方法,进行试验验证。结果表明,限制条件下的尺寸变化率测试方法符合水泥基自流平工程现场使用实际,能有效评估水泥基自流平砂浆整个生命周期的尺寸变化情况,是尺寸变化率测试的最佳方法。Several test methods of dimensional change rate for mortar are compared and analyzed, and the verification experiment is carried out. The test method of dimensional change rate under restricted conditions fits the actual application of cementitious self-levelling mortar engineering, and can effectively evaluate the dimensional change of cementitious self-levelling mortar during its life cycle, which is the best method for dimensional change rate test.

关 键 词：水泥基自流平砂浆 收缩性 限制条件下的尺寸变化率
