本文提出了粉煤灰砖抗冻性能新的试验方法——破坏面积法。这种方法有一定的科学根据,主要指标比较直观,衡量灵敏度尚高。也有不足之处,如测量面积还较麻烦,未能很好反映试件冻后内部结构的变化,有待进一步征求意见,继续改进。 This paper presents a new test method for the antifreeze performance of fly ash bricks—the destruction area method. This method has a certain scientific basis, the main indicators are more intuitive, and the measurement sensitivity is still high. There are also deficiencies, such as measuring the area is still more troublesome, failed to reflect the changes in the internal structure of the specimen after freezing, pending further comments, continue to improve.
