Concrete slabs are a prevalent construction element in buildings, constituting the majority of floors. They can be classified into two primary construction methods: cast-in-situ and precast slabs. Each method has its advantages and disadvantages. Therefore, composite slabs have become increasingly popular in recent decades due to their ability to combine the benefits of both cast-in-situ and precast slabs. Composite slabs are created by assembling precast panels manufactured in a factory on-site, followed by the pouring of concrete in place.

The precast prestressed concrete deck (PPCD) system represents a novel approach that could potentially gain acceptance in the construction industry by reducing formwork consumption, saving construction time, and lowering project costs. To investigate the efficacy of the PPCD system, this study conducted extensive experimental tests under various load scenarios, encompassing preparation, transportation, and installation. Finally, a four-point loading test was also carried out to test and analyse the flexural performance of PPCD.
