Cement-phenolic resin compositions

An adhesive composition comprising a curable phenol-aldehyde resin and from about 20 to about 55 percent based on the weight of the resin of portland cement wherein the phenol reactant used in making said resin is phenol or a mixture of phenol with up to about 90 mole percent of a substituted phenol having at least two of the positions ortho and para to the phenolic hydroxyl group unsubstituted and capable of reaction with an aldehyde and wherein the resin is a methylolated novolac or a resole obtained by reacting said phenol with formaldehyde in the presence of an acidic or an essentially neutral condensation catalyst and wherein the said phenol-formaldehyde resole or methylolated novolac is the product of reaction of about 0.05-0.5 gram mole per 100 grams of resole or novolac of at least one aromatic amine of the group consisting of aniline, ar-(lower alkyl)aniline, lower alkoxyaniline, and a difunctional aromatic amine of the formula ##STR3## wherein A represents a benzene ring, a naphthalene nucleus, or a dicyclic moiety of the formula ##STR4## wherein X is oxygen, lower alkylidene, S, SO.sub.2, or NH, n is zero or one, R is OH or NH.sub.2, and R' is H, lower alkyl, or lower alkoxy.
