Beschreibung
Zusammenfassung:	Process for providing improved head joints in concrete block construction comprising utilizing as the adhesive in the preparation of such head joints a plastic aqueous binder composition comprising a mixture of a hydraulic cement, a polymeric latex and a liquid synthetic thermosetting ambient temperature curable epoxide resin, and a polyamide curing agent therefor, wherein the binder composition is prepared by (1) preparing a first mixture of cement and thermosetting resin which first mixture is mixed on a compounding mill under conditions of high shear, (2) preparing a second mixture comprising a blend of the polymeric latex with the curing agent wherein the curing agent is dissolved in methyl alcohol, and (3) admixing the first and second mixtures prior to use as an adhesive.
