Patrick Arnold CM 2121 Materials, Methods, and Equipment Final Exam Prep All Matching I. Test #1 A. 1. Zoning Ordinances are laws that specify on detail how land may be used in a municipality. Building Codes protect the health and safety of people in the community. 2. The location of the water table at a building site will have a great effect on the foundation design and construction process. 3. The main components (basic raw material) for the manufacturing of Portland cement are lime, iron, silica, and alumina . Gypsum is added to retard the eventual curing process. 4. The aggregate used in the production of lightweight, structural concrete is often a manufactured product such as expanded shale . 5. A Bentonite Clay and Water Slurry is used to stabilize the earthen walls in concrete slurry wall construction. 6. Mat foundations are a single concrete footing that is essentially equal in area to the area of ground covered by the building. 7. A line of shoring is typically installed beneath the girders and beams for the support of elevated concrete formwork. 8. Most concrete domes are self-supporting concrete shell structures but would require a tension ring to counteract lateral loads. 9. Piles are test loaded by the used of other piles driven on either side of the test pile and having a jack test its strength. 10. Shoring is not required on post-tensioned concrete structures after the tendons have been tensioned. B. Matching 1. Shoring – temporary vertical or sloping supports of steel or timber.

Pile – a long slender piece of material driven into the ground to act as an element of a foundation. 5. Tie Back – a form of bracing for sheeting that is installed outside the excavation using a drill, tendons, grout and jack. 6. Reshoring – vertical supports used to distribute the load of a concrete floor system over several lower floors during construction. 7. Gang – formwork systems used to cast large sections of floor and/or wall units which are moved from bay to bay by crane. 8. Form Liner – used on the inside or bottom of forms to provide ribbed or textured architectural finishes. 9. Batter Board – are used to record the position of corner stakes. 10. Stirrup – a vertical loop of steel rebar used to reinforce a concrete beam against diagonal tension. 11. Ribbed Slab – a reinforced concrete framing system in which closely spaced concrete joists span between parallel girders. 12.
