What is a standard component of a CMU?

A standard component of a Concrete Masonry Unit (CMU) is steel reinforcing rods. These rods are typically incorporated into the design to enhance the structural integrity of the masonry. The reinforcement helps to withstand tensile forces that the concrete alone cannot handle effectively, making the units more resilient to various loads and stresses, such as those experienced in seismic or high-wind events.

In contrast, while concrete aggregates are essential in the overall composition of concrete, they are not a distinguishing characteristic of CMUs specifically. Plastic casing and wooden struts do not form part of CMU construction, as they either don't provide the necessary strength for masonry applications or are not typically used in the production of CMUs. Thus, the inclusion of steel reinforcing rods is critical in ensuring that CMUs fulfill their intended function in building construction and safety.
