Lesson 6
Working with Concrete

Concrete is the principal construction material used in most construction projects. The quality control of concrete and its placement are essential to ensure its final strength and appearance. Proper placement methods must be used to prevent segregation of the concrete. This lesson provides information and guidance for the forming, placement, finishing, and curing of concrete. Information is also provided on the placement of reinforcing steel, and the types of ties required to ensure non-movement of reinforcing once positioned. You will also be provided necessary information on concrete construction joints and the concrete saw. At the end of the chapter, you will find helpful references.
