摘　　要：采用灰色关联理论对结构物混凝土的早期抗冻能力影响因素进行研究,以抗冻临界强度作为评价指标,水灰比、冻结温度、粉煤灰掺量和硅灰掺量作为影响因素,试验研究发现:对混凝土的早期抗冻能力影响最大的是水灰比,其次是冻结温度和硅灰掺量,最后是粉煤灰掺量;本试验研究的水灰比、冻结温度、粉煤灰掺量和硅灰掺量四个因素与混凝土抗冻临界强度的灰色关联度均大于0.6,说明这四个因素对混凝土的早期抗冻性能均有重要影响。Use grey relational theory to study the influence factors of early frost resistance of concrete structures. Regard the critical strength of antifreeze as the evaluation index, the water-cement ratio, the freezing temperature, fly ash and silica fume as factors, The study found the ability of early frost resistance of concrete is most influenced by water-cement ratio, followed by freezing temperatures and silica fume content, and finally fly ash. Four factors in this study, water-cement ratio, the freezing temperatures, fly ash and silica fume, the grey correlation degrees among them and critical strength of antifreeze of concrete are more than 0.6, indicating that these four factors have an important influence on the performance of concrete early frost resistance.
