Common Concrete Surface Problem Definitions:

Popouts - deleterious material in aggregate absorbs moisture, freezes during the winter, expanding and "popping" off the top surface.  A small crater remains in the surface, and the remnants of the soft, deleterious material are still in the crater.  Common issue with gravel mixes.  Once the soft aggregate has popped, no further damage will be done to the slab.

Mortar Flaking - the surface layer of paste peels off the slab, leaving a sound piece of aggregate exposed.  Common problem with granite mixes if the curing was ineffective.  Usually limited to areas immediately above a submerged piece of non-porous, flat aggregate.  Damage often limited to a few spots where aggregates were close to the surface.

Scaling - top surface peels off the slab.  Typically not an aggregate problem.  Caused by too much water in the mix, lack of curing or water added to the surface and troweled back in while finishing.  Slab must be carefully assessed to determine if the problem is limited to the surface or if the entire slab is compromised. 

The table below lists many of the most commonly used mixes at Marshall, the application the mixes are used for, and a brief description of the mix.  We have hundreds of mixes to pick from, so if you don't see what you want here, just call us and tell us what you need and we'll be able to suggest a mix for you.
