Ch211l medium temperature retarder
Summary
Ch211l has little effect on other properties of cement paste.
Ch211l includes standard ch211l and antifreeze ch211l-a.
Ch211l is only suitable for water distribution. There is no special requirement for the quality of slurry preparation.
Particular attention
UseWhen the curing temperature of ch211l cement slurry system is lower than the circulating temperature, it has certain influence on the development of compressive strength.
When ch211l is applied above 100 ℃, the dosage will increase significantly.
