Precast Concrete: Its Types, Advantages, Manufacturing

2022-7-15 · 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.

Lattice girder slabs

Lattice girder slabs. Lattice girder slabs act as permanent formwork and as precast soffits for robust, high capacity composite floor slabs. They are cast with most, if not all, of the bottom reinforcement required; the top reinforcement is fixed in situ. The units are typically 50mm to 100mm thick and 1200mm or 2400mm wide.
