Perform fi nishing operations, including screeding, edging and jointing, fl oating, brooming, and form removal. Describe three basic types of joints used in concrete construction. Build a variety of patterns, textures, and decorative fi nishes into concrete during construction. Describe how cast-in-place concrete is used in walls and roof and fl oor systems. Describe the construction of precast/prestressed concrete systems. Concrete Flatwork and Formed Shapes CHAPTER 18 Tech Terms edging ponding screeding shotcrete tilt-up construction Concrete can be cast in practically any shape as long as a form can be built to contain it while it is in a plastic state. See Figure 18-1. This is one reason concrete is valuable as a building material. However, most concrete is formed into slabs on grade, cast in place as walls or floors, or used in the manufacture of precast units, such as beams and panels. This chapter covers the practical aspects of using concrete in these applications. Tilt-Up Concrete Association Figure 18-1.
