· Concrete offers excellent resistance to weathering and corrosion in most climates. High-density, large format precast concrete …
· this publication is to show how precast concrete may be mixed in combination with other structural materials to maximise overall building performance. The other materials are: cast insitu concrete, reinforced and post- tensioned, structural steelwork, timber and glue-laminated timber, masonry in brickwork and blockwork, glass and glazing.

· The top corners of the beam on either side are hunched to. provide good accessibility to the in-situ concrete at the connections. Channel sections are provided at a regular spacing to connect the. joists. fPrefabrication Elements. • Precast columns –. The special types of columns are used to hold the wall panel in.
· Advantages of precast concrete: Precast concrete has several advantages over cast-in-situ concrete: 1. When identical members are cast, it is advantageous for the same formwork to be used. 2. As better quality control can be exercised in the factory or yard site, concrete of superior quality can be produced. 3.
· Precast concrete is manufactured in plants under strictly controlled conditions, which means excellent resource efficiency for materials, labor, energy and processes. Most precast concrete facilities are clean and productive, with computer-controlled processes for batching, mixing and casting.

It should be noted that in-situ prestressed concrete uses the post-tensioning technique, while precast concrete industry uses pre-tensioning technique. In post-tensioning we use a small number of large tendons as opposed to a large number of individual strands in pre-tensioning. The behavior of bonded and unbonded members is the same as long as ...

· Precast concrete is reinforced concrete constructed by industrialized methods. It is characterized by dividing the building into components, which are manufactured in a precast concrete plant, and transported by special transportation equipment to the site. Precasting reduces construction time because the manufacturing of the elements is …
