This paper showed the results of experimental study on the effects of different types and adding amount of alkali on the loss rate of water and the drying shrinkage of cement paste.
The major loss caused by the method of washing with sulfuric acid was avoided, and the consumptions of sulfuric acid and alkali were decreased.
避免了传统硫酸酸洗法脱硫工艺中苯损失大、硫酸和碱用量大的问题。
