Which concrete system utilizes prefabricated, reusable metal or fiberglass forms to create waffle slabs for faster construction?

The correct answer focuses on the waffle slab system, which is specifically designed to utilize prefabricated, reusable metal or fiberglass forms. Waffle slabs are characterized by their grid pattern created by the intersecting ribs that form a grid, resembling a waffle. This design not only provides structural efficiency but also reduces the amount of concrete needed, leading to a lighter slab.

Using reusable forms in the construction process allows for quick assembly and disassembly, making the process faster compared to traditional pouring methods. This efficiency is beneficial in minimizing labor and time on site, which is a key advantage in the construction industry.

Additionally, the versatility of the waffle slab system lends itself to various applications, including commercial and institutional buildings, where large spans are often required. The properties of the prefabricated forms also contribute to the higher quality of finishes typically achieved with waffle slabs, optimizing both the structural integrity and aesthetic appeal of the project.
