Concrete Block Types Layout with Hollow Core Masonry Block Design

This drawing presents different types of concrete blocks used in masonry wall construction. The layout illustrates multiple hollow concrete block configurations showing internal core openings and block shapes used in structural and partition wall systems. Each block type is designed with hollow cores that help reduce weight while maintaining structural strength and stability. The drawing shows variations of block openings, including elongated hollow cavities and square hollow sections that improve bonding with mortar and reinforcement placement within masonry walls.
