✦ Synopsis

The writer was very interested in the reported results and would like to add additional comments on the subject of mortaraggregate bond strength.

The authors' conclusion concerning the insensitive nature of the friction component of bond strength when various polymer additives are used agreed with the writer's results obtained using similar test specimens but subject to polymer impregnation (after hardening) using methyl methacrylate (i). The writer showed that polymer impregnation had insignificant effects on compression-shear bond strength; thus showing that the high strength of polymer impregnated concrete is not because of improved bond strength.

Polymer-impregnated concretes, especially those based on acrylic-type polymers, have received considerable attention in recent years. In addition to exhibiting more than a three-fold increase in strength, these composites seem to manifest better durability characteristics than conventional concrete
