ABSTRACT:
Cementitious magnesia compositions are disclosed containing at least one of a family of organo-silicon compounds, each of which is characterized in having attached to the silicon atom at least one group hydrolyzable at the silicon atom and at least one group comprising a moiety that is attached to the silicon atom through a substantially non-hydrolyzable silicon-carbon bond. Magnesia compositions containing one of the described organo-silicon compounds, wherein the non-hydrolyzable moiety has a working parameter of solubility, .delta..sub.wp, typically in the range of about 6.2 to about 8.0 (cal./cc).sup.1/2, have improved casting, molding or spraying properties as compared to magnesia compositions lacking the organo-silicon compound.
