Concrete masonry blocks, commonly referred to as Concrete Masonry Units (CMUs), are a key construction material used in various types of building projects, both residential and commercial. They are formed from a mixture of cement, sand, gravel, and water, which is then molded and cured to produce a strong, durable block.
Types of Concrete Masonry Blocks
Standard Concrete Blocks (Hollow or Solid):
Hollow Blocks: These are the most common and have hollow cavities that make them lighter and easier to handle. The voids can be filled with steel reinforcement and grout to increase strength.
Solid Blocks: Heavier and more durable, solid blocks are used for load-bearing walls and structures requiring higher strength.
Split-Face Blocks:
These blocks have a rough, textured surface that gives a decorative look, often used in exterior walls for an aesthetic appeal.
