Zinc sulfate monohydrate used as retarder in cement production
Cement, stired into paste, can be better hardened in air or water and firmly cemented sand, stone together. But if cement is solidified too fast, it needs to add zinc sulfate monohydrate retarder and adjust the production process.
In cement production field, Rech Chemical’s customers purchase a variety of retarders, which roughly divided into two types: organic and inorganic, including zinc sulfate.
Organic retarder is characterized by tiny dosage that improper dosage can affect cement strength; The inorganic salt retarder is characterized by slightly more than organic retarder and its different retarding effect. Take zinc salt for an example, zinc salt includes zinc chloride, zinc sulfate, zinc carbonate, zinc nitrate and so on. Zinc salt retarder cannot work much when used alone, so zinc salt is usually compounded with organic retarder, which can reduce reduce bleeding without affecting concrete strength in the early period.
Considering the prices and its active ingredients, zinc sulfate monohydrate has become the common retarder in cement manufacturing industry.
