Through a series of experiments , the aging - resistance ability of hpch is increased one grade compared with the traditional materials , and the equal level with the foreign materials . the results of dry - wet circle test and quick test for chloride permeability show that the ability of efflorescence resistance of hpch is better . on the condition of 25 times circulation of dry - wet , there are a few non - development white spots just on the corner of specimens 通过干湿循环测试及快速氯离子渗透试验， hpch材料的抗析霜能力较强，在25次干湿循环条件下，仅在角部出现少量且不扩散的白斑，而传统装饰混凝土材料则出现延边棱迅速扩散的大面积析霜；快速氯离子渗透结果表明，在同样条件下hpch材料通过的电量(即离子迁移能力)仅为传统材料的49 . 68 ，比国外同期产品提高25 . 34 。
