Mortar Mixes
What Defines A Mortar Mix?
Mortar or commonly grout concrete is small aggregate concrete defined by its lack of larger gravel aggregates. Aggregates 1/8" and smaller can be used to make grout and mortar but most commonly masonry sand is used in various ratios for many different concrete applications. Tile setting, interlock stone setting, patch repairs and floor levelling are all examples of mortar concrete applications.

Sand can be mixed with cement powder in many different ratios which produces a finished concrete with differing properties. This cement mix is the strongest mortar mix ratio.
