What type of block is best for filled cell applications?

• A. 2 core
• B. Pier
• C. 3 core
• D. Partition

Answer: (A)

Filled cell construction relies on pouring grout into the hollow cores of masonry units to create a solid, reinforced member that carries loads more effectively. A block with two voids provides a straightforward path for grout to fill completely, helping the grout bond well with the surrounding masonry and any reinforcement. This setup promotes consistent fill and strong load transfer without the extra complexity or cost that comes with filling more cavities. A three-core block has an additional cavity to fill, which increases grout volume and labor; it can be harder to ensure every core is fully and cleanly filled, so the extra effort doesn’t always translate to a proportional strength gain for typical filled-cell applications. Partition blocks are intended for interior non-load-bearing walls, so they’re not optimized for filled-core reinforcement, and a pier is a vertical structural member rather than a block type designed for filling cores. Therefore, the two-core block strikes the best balance of ease of fill, structural performance, and cost for filled cell uses.
