I’ve been getting questioned about my material more frequently of late. “Is this concrete or is it really cement? Grout?” and the like.
Think about paints for a moment. There are many kinds of paint out there, used for many different purposes. There is oil paint, watercolor, enamel, spray paint, and so on. You can paint a house, or a table, or a piece of wall art. You wouldn’t use watercolor to paint a house, but you also wouldn’t (typically) paint a work of art with enamel house paint.
The same is true of concrete. I wouldn’t try to make a sidewalk with my mix, but it suits its intended purpose well.
Cement, think rubber cement, is like glue. Under the right conditions, it bonds and hardens. Concrete is a mixture of cement, solids (like gravel or sand), reinforcement (rebar, hemp, fiber, or the like) and other additives. Grout is a cement mix with fine sand aggregate. My mix is an artisan mix. It is a very fine mix with integral pigments, fine silica, polymer, and fiber reinforcement. I use ingredients that make it smooth, strong, and beautiful. When I make my mix, I am using quite a few ingredients. Its composition changes depending on what I am trying to make.
