Unit Weight of Different Building Materials. Standards applicable to cmu contain three classifications of weight, expressed in pounds per cubic foot: Normal Weight, Medium Weight, and Lightweight. Bevelled-end units, forming a 45° angle with the face of the unit, are used to form walls intersecting at 135° angles. %PDF-1.3 %���� TEK 2-6, Density-Related Properties of Concrete Masonry Assemblies (ref. Concrete masonry unit shapes have been developed for a wide variety of applications. Appendix C - Weights of Masonry Walls . 2), are available in a wide array of nominal lengths and heights; typically with a nominal 4 in. Architectural Concrete Masonry Units, TEK 2-3B, National Concrete Masonry Association, 2017. Concrete masonry solid blocks are manufactured with 2150 Kg/m3 density for normal weight blocks and 1100 Kg/m3 density for light-weight concrete blocks. Item: Weight (kg/m 3): Asbestos cement sheets: 12 to 15.6: Brick masonry: 1920: Brick wall, 100 mm thick: 192: Brick wall, 200 mm thick: 384: Brick wall, 300 mm thick Figure 3 shows units developed for specific wall applications. CMU must meet ASTM C90, which provides density ranges for each weight classification. Standard Specification for Concrete Facing Brick, ASTM C1634-15, ASTM International, 2015. TEK 2-3A Architectural Concrete Masonry Units. Blockwork Brickwork Concrete Glass Steel Timber. ft. and over. Specific unit weight of concrete - amount properties converter for conversion factor exchange from 1 cubic meter m3 equals = 23.60 kilonewtons kN exactly for the masonry material type.

(mm) Normal Weight. 5-4. An all-purpose or kerf unit contains two closely spaced webs in the center, rather than the typical single web. tw = Minimum web thickness, in. For more information on architectural surface finishes, see TEK 2-3A Architectural Concrete Masonry Units (ref. The taper provides a wider surface for mortar and easier handling for the mason. Lightweight London stock Normal reinforcement Clear float Mild Softwood. Full list of materials: Material. Allowable Working Stresses in Reinforced Masonry… Weight of CMU Walls, w 2, Pounds Per Square Foot. The unit weight of reinforcement concrete = 25 KN/m3 The unit weight of fine sand = 15.10 to 15.70 KN/m3. Thickness/ quantity of unit. (mm) Nominal dimensions refer to the module size for planning bond patterns and modular layout with respect to door and window openings. When it comes to block making, the State of Michigan is abundant with normal weight aggregates of sand, gravel, and limestone (ASTM C-33) throughout the state, which when utilized in the concrete block manufacturing process will result in concrete masonry units (CMU’s) that ASTM classifies as normal weight (density of 125 lbs/cf and above). Concrete Masonry Units . In addition to these standard sizes, other unit heights, lengths, and thicknesses may be available from local concrete masonry producers. Having converted the mass unit into a weight figure we can now calculate the weight of any structural component or member in newtons by using: W = kN/m 3 × m 3. Bond beam units are either manufactured with reduced webs or with “knock-out” webs, which are removed prior to unit placement in the wall. Lintel units are available in various depths to carry appropriate lintel loads over door and window openings. 0 Pilaster and column units are used to easily accommodate a wall-column or wall- pilaster interface, allowing space for vertical reinforcement in the hollow center. (203 mm) by 16 in. Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units, ASTM C140/C140M-16, ASTM International, 2016. Concrete Masonry Units are required to meet the requirements of Australian/New Zealand Standard AS/NZS 4455 Part 1 . Open-ended units allow the units to be threaded around reinforcing bars. As with brick, CMUs have actual dimensions and nominal dimensions. Masonry Structures in 2002. h�bbd``b`j�@��>�`�[$�'��� �)���"� U3�H�+Hl����Ȱd#��e_ Ob Concrete Masonry Walls do not burn. To convert concrete measuring units can be useful when building with concrete and where handling of … Hence the adopted thickness of 100mm with M1 mortar and masonry unit with compressive strength 10N/mm 2 is not safe in carrying the load from slab. This eliminates the need to lift units over the top of the reinforcing bar, or to thread the reinforcement through the masonry cores after the wall is constructed. The graphic below shows the difference between nominal and actual sizes. (203 mm) long units, which are typically used adjacent to openings or at the ends or corner of a wall.
