How are concrete masonry units made?
During the past 100 years, manufacture of concrete masonry units (CMU) transitioned from a hand cast process to a highly automated one. Single molds compacted by hand gave way to ganged molds that travel on assembly lines in high-tech manufacturing facilities. These changes have also led to excellent quality control and uniformity of units.

How long is a CMU block?
In the US, CMU blocks are nominally 16 in (410 mm) long and 8 in (200 mm) wide.
What is a CMU?
A building constructed with concrete masonry blocks. A concrete masonry unit ( CMU) is a standard size rectangular block used in building construction. CMUs are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them. Those that use cinders ( fly ash or bottom ash) ...
Why are concrete blocks hollow?
Concrete blocks may be produced with hollow centers (cores) to reduce weight, improve insulation and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built.
What is cinder block?
Those that use cinders ( fly ash or bottom ash) as an aggregate material are called cinder blocks in the United States, breeze blocks ( breeze is a synonym of ash) in the United Kingdom, and hollow blocks in the Philippines. In New Zealand and Canada they are known as concrete blocks (a name common in the United States also).
What is a crawl space foundation?
One of the common foundation types for American suburban houses is the "crawl space foundation" which consists of a concrete block wall around the perimeter on which dimensional lumber floor joists are supported.
What are recycled materials?
Recycled materials, such as post-consumer glass, slag cement, or recycled aggregate , are often used in the composition of the blocks. Use of recycled materials within blocks can create different appearances in the block, such as a terrazzo finish, and may help the finished structure earn LEED certification.
Can concrete be grouted?
Concrete masonry walls may be ungrouted, partially grouted, or fully grouted, the latter two enhancing their structural strength. Additionally, steel reinforcement bars ( rebar) can be used both vertically and horizontally inside a CMU wall to maximize its structural performance.
What is CMU in construction?
During the past 100 years, manufacture of concrete masonry units (CMU) transitioned from a hand cast process to a highly automated one. Single molds compacted by hand gave way to ganged molds that travel on assembly lines in high-tech manufacturing facilities. These changes have also led to excellent quality control and uniformity of units.
What is a CMU wall?
CMU are modular. The most common size is a nominal 8-by-8-by-16- inches. Door and window openings are positioned to minimize cutting of units. Walls that contain one vertical layer of units are called single wythe and two layers are double wythe. It is most common to build single- or double-wythe walls. When wythes are separated by a continuous vertical space, the assembly is known as a cavity wall. Units are held together by mortar.
Why do we need insulation in walls?
This helps walls to carry loads and resist other forces acting on them. Insulation may be added to interior or exterior faces, between wythes, or inside special unit cavities. The benefit of keeping the insulation inside the wall is that the masonry faces are quite durable.
What is a CMS?
Concrete masonry systems (CMS) are familiar to most people because they have been used for such a long time. All types of low-rise buildings are made with these materials, from residential to educational to commercial and industrial. The tough exterior of exposed units provides a durable finish in demanding environments.
Where is Twenhofel Middle School?
Located near Cincinnati, Twenhofel Middle School was one of Kentucky’s first schools to incorporate sustainable building principles and energy conservation measures. In 2004, these ideas were not necessarily revolutionary, but neither had they been the focus of school administrators prior to that time.
Why is concrete masonry so popular?
The backbone of this school is concrete masonry. Generally, one reason concrete masonry has been so popular in schools is its durability. Hard surfaces stand up to wear and tear that is so common in schools and other high usage areas.
Is concrete masonry sustainable?
Concrete masonry is sustainable for a number of reasons. It can contain recycled materials. It is made from local materials and usually shipped short distances to a project. These aspects often contribute toward credits in green rating systems.
How long should I mix mortar?
Specification for Masonry Structures (ref. 7) requires that these materials be mixed for 3 to 5 minutes. If the mortar is not mixed long enough, the mortar mixture may not attain the uniformity necessary for the desired performance. A longer mixing time can increase workability, water retention, and board life.
How many times can a mason lay a block?
Experienced masons state that they can lay about five times as many masonry units when working to a mason line than when using just their straightedge. The mason line gives the mason a guide to lay the block straight, plumb, at the right height, and level. The line is attached so that it gives a guide in aligning the top of the course.
Why is concrete masonry used?
Concrete masonry is a popular building material because of its strength, durability, economy, and its resistance to fire, noise, and insects. To function as designed however, concrete masonry buildings must be constructed properly.
What are the constituent materials of masonry?
The constituent masonry materials: concrete block, mortar, grout, and steel, each contribute to the performance of a masonry structure. Concrete masonry units provide strength, durability, fire resistance, energy efficiency, and sound attenuation to a wall system. In addition, concrete masonry units are manufactured in a wide variety of sizes, ...
Why is grout used in masonry?
Grout is used to fill masonry cores or wall cavities to improve the structural performance and/or fire resistance of masonry. Grout is most commonly used in reinforced construction, to structurally bond the steel reinforcing bars to the masonry, allowing the two elements to act as one unit in resisting loads.
What is mortar bonding?
Mortar bonds the individual masonry units together, allowing them to act as a composite structural assembly. In addition, mortar seals joints against moisture and air leakage and bonds to joint reinforcement, anchors, and ties to help ensure all elements perform as a unit.
How thick is mortar in a head?
Head and bed joints are typically ⅜ in. (10 mm) thick, except at foundations. Mortar should extend fully across bedding surfaces of hollow units for the thickness of the face shell, so that joints will be completely filled. Solid units are required to be fully bedded in mortar.

Nominal vs. Actual Dimensions
Concrete Block (CMU) Sizes
- Concrete Masonry Units (CMUs) are manufactured in a variety of sizes. They are identified by their depth – i.e. the thickness of the wall they create. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep. Concrete blocks also come in half-sizes, which are helpful in reducing the need to cut blocks in the field at corner...
Concrete Masonry Unit (CMU) Specifications
- CMU manufacturers must conform to ASTM standards when fabricating concrete blocks. The standards identify appropriate materials, compressive strength, dimensional tolerance, moisture absorption, and other performance characteristics. Concrete brick is made from concrete similar to concrete block, but concrete bricks are fabricated in sizes that match traditional clay bricks (i.…
Concrete Masonry Unit (CMU) Shapes
- There are an almost infinite number of CMU shapes available. The images below cover the most common shapes, but you should check with your local CMU manufacturer if you need special shapes or finishes.
Concrete Masonry Unit (CMU) Surface Finishes
- As with shapes, there are a large number of finish options so you can make the utilitarian gray concrete block look much more aesthetically pleasing. Be sure to meet with your local CMU representative to learn about what types of finishes they offer and at what cost premium.
