ABSTRACT:
Retarding the hardening of a composition containing a phenolic resin solution and a magnesia aggregate is effected by mixing into such composition a compound which provides an aspartate, fluoride, bifluoride, malate, tartrate, citrate, oxalate, phosphate or phosphonate anion to the composition or a tetraalkoxy silane, a partially hydrolyzed tetraalkoxy silane, 2-, or 4-chlorophenol, or 2'-, or 4'-hydroxyacetophenone.
