Aggregates for Concrete
CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.

Acid Wash Exposed Aggregate Concrete: A Complete Guide
The Acid Wash Process. To begin the acid wash process, the surface must be thoroughly cleaned and prepped. This involves removing any dirt, debris, or stains from the surface. Once the surface is clean, an acid solution is applied to the surface. The acid reacts with the cement paste, dissolving it and exposing the aggregate beneath.
