Lighter CMUs are less expensive, require less labor to install, and tend to have better fire resistance properties. There are three classifications of CMU: lightweight (less than 105 lb/ft 3), medium weight (between 105 lb/ft 3 and 125 lb/ft, and normal weight (more than 125 lb/ft 3. The weight of concrete masonry units varies depending on the density of concrete mix used. The standards identify appropriate materials, compressive strength, dimensional tolerance, moisture absorption, and other performance characteristics.Ĭoncrete brick is made from concrete similar to concrete block, but concrete bricks are fabricated in sizes that match traditional clay bricks (i.e. CMU SIZEĬoncrete Masonry Unit (CMU) SpecificationsĬMU manufacturers must conform to ASTM standards when fabricating concrete blocks. While 4", 6", 8", 10", and 12" are the standard sizes, some manufacturers offer other sizes not listed below. The following table provides concrete block sizes in both nominal and actual dimensions. The architect should always attempt to design buildings using the nominal dimensions to the nearest half-block size to reduce waste and labor due to cut blocks. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep.Ĭoncrete blocks also come in half-sizes, which are helpful in reducing the need to cut blocks in the field at corners or the end of walls. They are identified by their depth – i.e. These lightweight unit’s equal dollars in your pocket, as they reduce labor and freight cost.Concrete Block - Nominal vs Actual Dimensions Concrete Block (CMU) SizesĬoncrete Masonry Units (CMUs) are manufactured in a variety of sizes. Our local materials allow us to produce light weight units that meet or exceed the compression strength and absorption results of any regular block on the market.
One other advantage to using our block is that the units we produce are lighter than any of our competitors. This allows us to accommodate our customers better than any of our competitors. The model of our company allows us to compete at a high level, as we are big enough to produce volume in nearly every type of CMU available in the market, but we are small enough to adapt and shiftquickly when necessary. We have the ability to uphold these high standards because of our amazing people, having a team with over 100 years of combined experience in the block manufacturing business! In addition to our quality, is our capacity to produce and our unbeatable service. For questions about special orders items or general questions, please contact our sales office, or inquire online.Ĭoncrete Masonry Units manufactured by Block-Lite are held to the highest standards in the industry.

We offer a full line of colors that you may view online or feel free to contact us and we will have samples sent directly to you. These include smooth face, split face, ground face, shot blast, stri-face, flashed, vertical score, fluted, bullnose, slump, tumbled, and more. Units may also be uniquely machined or further processed to obtain a wide variety face styles and textures. These mix designs are made up of various combinations of the following specifications weight classification, aggregate type and size, integral color, integral water repellant, flashed color, and other specialty admixtures. All units can be manufactured using a wide variety of mix designs. And when purposely designed can create timeless beauty.īlock-Lite offers a large selection of concrete masonry units. CMU’s provide unmatchable performance in safety, strength, and longevity. When it comes to designing a structure that requires high performance and low maintenance, while also providing beautiful architectural detail, Concrete masonry units have stood the test of time in their ability to deliver.
