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.

A gradation analysis (or sieve analysis) is a procedure used to assess the particle size distribution (gradation) of a granular material by allowing the material to pass through a …
