Method of grafting organic groups on calcium silicates

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 im...

Zusammenfassung:	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.
