· In order to provide recycled aggregates 10 bricks will be crushed. These will be used as recycled aggregates in the mixes at different percentages. The coarse aggregate will replace gravel at the following percentages; 0%, 25%, 50%, 75%, 100%. Moreover, the fine aggregate will replace sand at the same proportions.

Defining Crusher Run Gravel. Crusher run gravel, also known as crusher run, crush ‘n run, or graded aggregate base (GAB), refers to a type of crushed stone aggregate material that provides foundational support and drainage for infrastructure projects. It typically contains a blend of stone, sand, and fines produced by crushing quarried rock.

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.

:Crushed Concrete AggregatesConcrete and CementCivil EngineeringAggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
