Question: 1 / 400

What is a primary benefit of a CMU having a thicker shell?

Increased aesthetic appeal

Better sound insulation

Improved structural integrity

A thicker shell in a Concrete Masonry Unit (CMU) contributes significantly to the improved structural integrity of the unit. Thicker shells provide greater overall strength and load-bearing capacity, allowing the CMU to withstand more substantial forces and stresses. This makes the block more effective in supporting weight from above, resisting lateral loads such as those from wind or seismic activity, and generally enhancing the durability of the structure in which it is used.

In addition, the increased mass of the thicker shell can aid in reducing the likelihood of cracking and damage over time, which further supports the overall longevity and stability of the masonry construction. This structural advantage is vital in ensuring the safety and resilience of buildings, particularly in areas that face challenging environmental conditions or heavy usage.
