Single Wythe 8 inch Concrete Masonry Walls
Most contemporary masonry walls consist of two separate wythes, comprised of one wythe of brick and one wythe of concrete masonry. However, there is an alternative masonry wall design that can produce economical and structural benefits. Concrete masonry units are strong in compression and can be produced with strengths in excess of 3000 p.s.i. This […]
Masonry Movement Joints
All masonry walls will move, primarily due to changes in temperature and moisture content. Additional movement might occur from structural concrete frame moisture loss or creep, and elastic deformation. Restraining these movements may cause stress cracks to develop in the wall. The type of movement will depend upon materials, construction, and wall configuration. The primary […]
