May 02, 2021  Prestressed concrete cylinder pipes (PCCPs) are widely used for water mains and wastewater lines that serve almost every major city in Morocco. By all accounts, PCCPs have performed relatively well over the years. However, in 2016, the Agadir Authority found failures due to widespread corrosion of the prestressing wires and water hammer damage.

Enhancing the shear strength of hollow-core slabs by using ...

Hollow-core slabs (HCS) are precast slabs of prestressed concrete widely used in the construction of residential parking and industrial buildings floors credit to the benefits they present: i.e. high-quality control, ease installation and reduced construction time – among others. Typically, they are manufactured by extrusion or slip-formworks using concrete with very low workability.

Prestressed Concrete : GCCA

Prestressed Concrete. Prestressing can reduce the volume of concrete required in construction, lowering the use and transportation of materials, as well as boosting durability and service life. Concrete is intrinsically resistant to compressive stresses, but its resistance to tension is much lower. To provide tensile capacity, reinforcement can ...

Containment performance evaluation of prestressed

The containment performance of a prestressed concrete containment vessel (PCCV) will be improved through a significant decrease of the crack open area and the pre-vention of through-wall cracks. Fibers can be successfully used for improving the containment performance of the PCCVs by reducing the cracks in the containment concrete.
