ASTM C90 Standard Specification for Loadbearing Concrete Masonry Units NOTE: beginning in 2000, ASTM C90 no longer contained Grade or Type designations. Because up to 90 percent of a concrete masonry unit is aggregate, the type of aggregate used will determine the weight classification. ry units. Pewter Square Concrete Step Stone-73700. In a solid wall, the vertical space between the wythes is about 314 in. Also, Fire rated, STC rated, and, Natural Stone, and Fireplaces. manufacturers have developed concrete masonry units with two cross-webs, rather than three. Basalite concrete masonry units (CMUs) are available in a variety of shapes, colors and textures. low strength mortar. Types of Hollow Concrete Blocks: Concrete Stretcher Blocks; Concrete Corner Blocks; Concrete Pillar Blocks; Jamb Concrete Blocks; Partition Concrete Block; Lintel Blocks; Frogged Brick Blocks; Bullnose Concrete Block Most Common Types Of Concrete Masonry Units The cement-aggregate ratio in concrete blocks is 1:6.

In New Zealand, they are also called Types of Concrete Blocks or Concrete Masonry Unit: Hollow & Solid Concrete Blocks. Concrete blocks are made from precast concrete, i. 2. Each can be made into four types of mortar, designated by the letters M, S, N, and O (taken from the word "masonry"). Glazed face units are perfect for many commercial, retail, institutional and industrial applications with their impervious surface, flexible design options, and recycled content. The letters indicate each type's tested compressive strength, which is achieved by adding or reducing the percentage of portland cement in the mix. PO Box 168 Halfway House 1685 Tel +27 11 805 6742, Fax +27 11 315 4683 e-mail: cma@cis. The term "architectural concrete masonry units" typically is used to describe units displaying any one of several surface finishes that affects the texture of the unit, many times allowing the structural wall and finished surface to be installed in a single step. One possibility is through the unit strength method. block are as follows: NORMAL WEIGHT CONCRETE • Type N Concrete The coarse aggregate is limestone, calcareous gravel, or similar dense aggregate material. Figure 8-4. Face shell mortar bedding has a narrow bed of mortar at the faces of the masonry unit and should only be used in interior non-load-bearing construction. 0 Ah Battery and Charger Included-P2080. 5x10-4 4.

They include stretcher, comer, double comer or pier, jamb, header, bull nose, and partition block, and concrete floor units. There are two types of grout specified in NZS 4210, one for use in standard concrete masonry and one for use mainly in between skins of brick or blockwork. Soil-cement, roller-compacted concrete and cement bound granular mixture - "cousins" of concrete - are used for pavements and dams. za website: www. Palumbo Block Co. Some inserts extend beyond the cores of the masonry to cover the mortar joint area and provide more continuous insulation coverage. 3) Materials & Resources Credit-Construction Waste Management Intact and unused masonry units can easily be returned to our facility and redirected to other projects. 1) concrete masonry units must be made with aggregates that meet either ASTM C A concrete masonry unit (CMU) is a rectangular block made of concrete which is also referred to as a cement block or concrete block. Of particular concern is drying shrinkage of concrete masonry during early curing and drying of masonry walls, which introduces tension stresses into masonry units. It should fit snugly but drive in easily with a hammer. A new generation of advanced products incorporates fibers and special aggregates to create roofing tiles, shake shingles, lap siding, and countertops. For nearly three decades, Masonry Resource Company, LLC has been a leading supplier of masonry and concrete products, CMUs, and a resource to architects and builders throughout the Midwest. These aggregates when mixed with cement and water produce the specific block physical properties inherent to the locally available aggregates. Therefore, specifications calling for Grade N, Type I (or Grade N-I), "moisture-controlled" units are no longer valid. lintel ___ tile is a type of ceramic tile used to cover walls or floors, and is available in 1'' square, 2'' square, and 1'' x 2'' sizes. Most mix designs for CMU range between 85pcf and 140pcf+.
