ChemCo Epoxies for ASTM C 881. Overlays or patching materials of new Portland Cement Concrete (PCC), terrazzo, mortar, grout and extruded curb based on Type I through Type V cements or White Cement may be structurally bonded with liquid epoxy adhesives to existing concrete surfaces.
The ratio to mix mortar is historically accepted as 1:3 of sand and cement. Mortar is a mixture of cement used in the building trade to hold bricks together. The type of sand and cement mixture needed will dictate the exact ratio. This varies according to the needs of the task: above ground is 5:1, below ground is 3:1 and internal walls is 8:1.
Concrete would have gotten an F. There is nothing in basic portland cement that will act as a bonding agent. Portland cement concrete works well in mass and provides great compressive strength but not bond. Concrete is marvelous stuff but in time it will deteriorate. When it does, you either have to patch it or replace it.
