§ The example in Section 8.2 illustrates the design of an intermediate precast concrete shear wall building in a region of low or moderate seismicity, which is where many precast concrete seismic force-resisting systems are constructed. The precast concrete walls in this example resist the Lake Cascade Utility Building PRECAST CONCRETE UTIILITY BUILDING 3 DPW17540 9/4/18 3. Fabricator shall, upon request, show four examples of precast concrete units produced, installed, and in use as examples of fabricator's ability to perform this contract. 4. Lecture 3 -Precast Concrete in Building Precast Concrete •Concrete elements, cast and cured in a manufacturing plant, then transported to the construction site. Precast Concrete •Structural elements are commonly reinforced with tightly stretched pretensioned steel strandswhichprovidestrands, which provide • Precast concrete non-load bearing façade panels. • Precast concrete floor system, either: - Precast concrete beams and precast slabs (reinforced concrete or prestressed) with a composite in-situ topping or Precast concrete walls with precast concrete slab system Figure 3.1 Precast prestressed slabs spanning between walls with composite The work can be completed in a short time, when precast units are adopted. When precast structures are to be installed, it is evident that the amount of scaffolding and formwork is considerably reduced. Precast Concrete Disadvantages of Precast Concrete. Following are the disadvantages of precast concrete: If not properly handled, the precast Guide specifications for specifying precast/prestressed concrete are available below.

The typical section for these precast concrete culvert shapes is shown in Figure 3, and the span capability is shown in Table 1. The span capabilities of these precast concrete culvert shapes are based on 6.0 ksi compressive strength of concrete, and grade 60.0 ksi reinforcement. The • For precast noise barriers it is the bottom or back face. 10.2.3 Early Removal of Formwork: Precast formwork is often removed the day after casting to speed up the construction process. If concrete laitance stick to the formwork, it is likely that too much shutter oil, which is a retarder, has ITEM 557.21010016 - FIELD CAST JOINTS BETWEEN PRECAST CONCRETE UNITS Page 2 of 3 June 3, 2011 specimens. The test will be performed as soon as practical after the corresponding samples reach 12 ksi. This test is a pullout test. The samples pass if the bars yield without the UHPC failing and without the bars pulling out of the UHPC. According to 'Precast Concrete Institute, U.S.A' (Published in: Designing with Precast and Prestressed Concrete), precast concrete is cast into a specific shape at a location other than building site like factories. The concrete is placed into a form, typically wood or steel, and is cured.
