Prestressed Precast Concrete - Elements, Advantage ...

13/06/2020  Difference between prestressed and non-prestressed precast concrete elements. Prestressing can be utilized to achieve higher span- to-depth ratios and provide increased resistance to cracking. It can be applied to precast as well as cast-in-situ concrete elements. Prestressing is generally incorporated into a member using pre-tensioning and post-tensioning processes.

Hollowcore Flooring Precast Concrete Floors by Longley

Hollowcore floor planks are precast concrete elements with continuous longitudinal voids providing an efficient lightweight section. When grouted, the shear key between adjacent planks ensures that the individual planks behave similarly to a monolithic slab. Hollowcore planks may be used to produce a diaphragm to resist horizontal forces, either with or without a structural topping. Benefits ...
