I wanted to choose this material to have a texture in the refrence catalogue. I wanted with sand
to make sure I knew how to make a texture without it being dusty or flaking off of the
product. I like this materials’ texture and colour subtly, while not being plain.

In its simplest form, concrete is a mixture of paste and aggregates. The paste,
composed of portland cement and water, coats the surface of the fine (small) and
coarse (larger) aggregates. Through a chemical reaction called hydration, the paste Original idea

The key to achieving a strong, durable concrete rests in the careful proportioning and the sand
mixing of the ingredients. A mix is about 10-15% cement, 60-75% aggregate and exposed, but
