Summary
DOC-C81, 300-mesh silica powder, is applied to keep compressive strength of set cement from declining and reduce permeability of set cement.
Properties and characteristics
1. High purity.
2. Reasonable particle size distribution, and prepared cement slurry with such material has good rheological properties.
