在掺流化剂(高效减水剂)的砂浆和混凝土中使用饱和盐溶液时将会导致大量的空气引入,在盐与高效减水剂之间可能存在不相容性,我们对含盐的砂浆和混凝土使用各种高效减水剂时的引气情况,进行了下列试验。将已量好的100克水加入试验室使用的带搅拌器的盛液器皿中,然后把高效减水剂(粉状或液体状)加到水中,用4~#搅拌器搅拌 The use of saturated salt solutions in mortars and concrete with fluidizers (high-range water-reducing agents) will result in the introduction of large amounts of air. There may be incompatibilities between salt and superplasticizers. The following tests were conducted for bleed air when mortar and concrete were used with various superplasticizers. Add 100 g of water to the test chamber and add it to a mixing vessel with a stirrer. Add the superplasticizer (powder or liquid) to the water and stir it with a 4~# mixer.
