Summary
DOC-A90S/CA903S is composed of a variety of inorganic salts. It can largely shorten the thickening time and cementing time of the cement slurry, increase the early compressive strength of the set cement.
It has no special requirements for water quality of mixing slurry. It can be used dry mixing or wet mixing.
Usage range
Temperature: 20~60℃.
Recommended dosage：2.0~4.0% (BWOC) .
Recommended wet mixing.
