Standard Brick sizes in the United States: In the US, modern normal bricks (controlled by the American Society for Testing and Materials i.e. of bricks required in a wall. Actual size (or the specified size), is the real dimension of the brick. On the other hand, if bricks are small, more quantity of mortar is required. American bricks are about 8 x 4 x 2.25 inches (203 x 102 x 57 mm) South African 8.75 x 4 x 3 inches (222 x 106 x 73mm) and in Australia they are 9 x 4.33 x 3 inches (230 x 110 x 76mm). b. Estimate Brickwork (V): Let’s assume V=1 m³ The standard brick size in the US is 203 mm × 92 mm × 57 mm as recommended by the American Society for Testing and Materials. 5. The higher the density and the strength, the better they will be. Now I’d like to hear from you, which section was new to you or maybe I missed something. A rat-trap bond is a type of wall brick masonry bond in which edge is used to leading the brick, not in the center. (6.4 mm), except: a. Size of brick in metre=0.230 ×0.115×0.075 Adding 10 mm mortar thickness in size of brick. If you choose a half brick laying, then the ceiling thickness will be 120 mm, one brick - 259 mm, two bricks - 510 mm (in addition to the blocks, 10 mm of cement mortar, which fills the layers) and 2.5 bricks - 640 mm. Some bricks are made with different work sizes. for each successive 10.668m (35 ft.) height or fractions of this height measured from the top of the masonry wall. Cheers C. Let your imagination run wild! The impact of strength of both mortar and brick on compressive strength of brick masonry were studied. Brick Size: An standard size of 230mm x 110mm x 55mm Mortar Thickness: Assume 10mm thickness of mortar and add on standard dimensions of the brick i.e size of a brick with 10 mm mortar joint-240mmx120mmx65mm. With mortar thickness, the dimension of the brick becomes 200 mm x 100 mm x 100 mm which is also known as the nominal size of the modular brick. The mason laid the brick with head joints as small as 3/16 inch and as large as 1/2 inch to overcome the size variation. Tolerances of -10 mm on length, -5 mm on width and ±3 mm on thickness shall be acceptable for the purpose of thick walls in this Mandatory Rules of Thumb (MRT). To choose the type of brickwork, you should consider the conditions of the building design. Bigger bricks are sometimes used for extra economical laying and as a design characteristic either by themselves or mixed with smaller bricks. With mortar thickness, the size of such a brick becomes 200 mm x 100 mm x 100 mm (8 inch x 4 inch x 4 inch) and it is known as the nominal size of the modular brick. So let’s get started. According to National Building Code (NBC 205 : 1994) of Nepal, the bricks shall be of a standard rectangular shape, burnt red, hand-formed or machine-made, and of crushing strength not less than 3.5 N/mm². With the thickness of the mortar, the dimension of the brick turns into 200 mm x 100 mm x 100 mm which is often known as the nominal size of a minor brick. The thickness of load bearing masonry wall should be at least 304.8 mm (1 ft.) thick for maximum wall height of 10.668m (35 ft.). What is the thickness of wall? Save my name, email, and website in this browser for the next time I comment. Continue this process every time you lay the bricks.

A generally used modular brick is 7 5 /8 × 3 5 × 8 × 2 1/ inches (194 × 92 × 57 inches). In this case the co-ordinating metric works because the length of a single brick (215 mm) is equal to the total of the width of a brick (102.5 mm) plus a perpend (10 mm) plus the width of a second brick (102.5 mm). Standard brick size & dimensions are 240 x 115 x 57 mm with 10 mm horizontal and vertical mortar joints. So interested here to know what maximum bed joint thickness would be permitted before compressive strength of the mortar might be affected. Wider (150 mm wide) bricks can also be used in walls requiring lower sound transmission, higher fire resistance levels and higher load bearing capacity depending on the specific brick properties. Of Bricks Larger bricks are often used for more economical laying and as a design feature either on their own or combined with smaller bricks. The mortar joint makes a unit dimension of 225 × 112.5 × 75 mm (9 × 4 1/2 × 3 in) for a ratio of 6 × 3: 2. In cyclonic areas larger (140 mm wide x 90 mm high x 290 mm long) hollow bricks are used to allow reinforcement and grouting in the wall. ASTM) are approximately 8 × 3 5⁄8 × 2 1⁄4 in.
