Method of grafting organic groups on calcium silicates |
摘要 |
Organosilicon groups are grafted onto calcium silicates by treating the calcium silicates with an organosilane or hydrolyzable organosiloxane in an acidified alkanol containing a water-soluble calcium salt. The treated calcium silicates are useful in the production of cement-based products having improved resistance to weather and corrosive agents.
