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.

The principles for the 3D printed concrete is the satisfaction of pumping and shape retention of concrete after extrusion through the hose. In this study, the quarry dust with particle sizes up to 98% passing 2 mm sieve and rubber particles with particle sizes up to 39% passing 2 mm sieve (purchased from Shaanxi Hongrui Rubber Products Ltd.) …
