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. There are also polymers used to make the cement waterproof or sufficiently elastic so that it acts like an anti-fracture membrane. 15 MM cement plaster is required on the rough side of 9” and 4.5” wall. 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. Let your imagination run wild! This gives a ratio of 3:2:1, meaning that: With a standard mortar joint of 10 mm, a repeating unit of bricks laid in a stretcher bond will be 225 mm lengthwise and 75 mm in height. Standard brick size & dimensions are 240 x 115 x 57 mm with 10 mm horizontal and vertical mortar joints. TMS 602-13/ACI 530.1-13 3.3.B Placing mortar and units indicates that a 3/8" (9.5mm)thick bed is anticipated/typical. Thus the nominal size of the brick includes the mortar thickness. The standard co-ordinating size for brickwork is 225 mm x 112.5 mm x 75 mm (length x depth x height). So interested here to know what maximum bed joint thickness would be permitted before compressive strength of the mortar might be affected. 15 MM cement plaster is required on the rough side of 9” and 4.5” wall. For calculating the number of bricks, the thickness of plaster should be deducted from the thickness … Different countries have different standard brick size and dimensions, however brick could be made in lots of sizes and shapes, depending on its application. 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. In India, the usual brick size is 190 mm x 90 mm x 90 mm as per the recommendation of BIS. So let’s get started. In India, standard brick size is 190 mm x 90 mm x 90 mm as per the recommendation of BIS. 1/4 - in. There are several cases in which the above conditions may not be applied for load bearing masonry walls. Some bricks are made with different work sizes. The average thickness of the different types of masonry: half-brick wall (single leaf wall) – 120 mm; single wythe (one brick thick wall) – 250 mm; 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. The description of various structural and non-structural parts for three-story reinforced concrete (RC), simple residential building, built by proprietors in Nepal. 50 mm and 90 mm high bricks, 90 mm wide bricks and 290 mm long bricks are used for different structural and aesthetic effect. 3.3.F Site tolerances indicates that the bed joints between courses may vary by +/- 1/8" (3.2mm). Moreover, the thickness of masonry wall need to be increased by 101.6 mm (4in.) 1. Thickness of -10 mm on length, -5 mm on width and 3 mm on thickness would be acceptable for the purpose of thick walls on this mandatory rule (MRT). 9.20.4.2. The thickness of the mortar should not be more than 10 mm between the courses and sides of the bricks. Moreover, the thickness of masonry wall need to be increased by 101.6 mm (4in.)

Estimate Brickwork (V): Let’s assume V=1 m³ Brick can be made in multiple shapes and sizes, depending on the application. Hi.. Genrally for tile flooring cement -mortor ratio varies from 1:5 to 1:9 for 50mm thickness. for each successive 10.668m (35 ft.) height or fractions of this height measured from the top of the masonry … of bricks required in a wall. 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. The mortar thickness of 12 mm was maintain throughout the study. For brick walls, a common thickness is 230mm or 9" (finished thickness). The more commonly used is the modular brick 7 5⁄8  × 3 5⁄8  × 2 1⁄4 inches (194 × 92 × 57 mm). Note: The primary goal of these mandatory rules of thumb (MRT) in Nepal’s Nationwide Construction Code is to offer ready to use dimensions. We generally adopt 10-16mm of thickness between each layer of Bricks. BRICK MASONRY | HOLLOW BLOCK | STONE MASONRY | BRICK BONDS. of bricks required for 1 cubic meter, No. The standard dimension of a modern brick is 215 × 102.5 × 65 mm (approximately 8 5⁄8 × 4 1⁄8 × 2 5⁄8 inch), with a nominal 10 mm (3⁄8 inch). The compressive strength was determined by masonry prism specimen and the shear bond strength was determined by triplet specimens in this investigation [1] . Copyright © 2020 | Powered by Civil Engineering Blog, Top Civil Engineering Schools, Universities. (203 × 92 × 57 mm). Various countries have various standard brick size and dimensions, however, brick can be made in multiple shapes and sizes, depending on its application. This includes 10 mm mortar joints, and so the standard size for a brick itself is 215 mm x 102.5 mm x 65 mm (length x depth x height). Volume of 1 brick with mortar = 200 X 100 X 100 ( 10 mm mortar thickness on all sides) = 0.2 X 0.1 X 0.1 . This includes 10 mm mortar joints, and so the standard size for a brick itself is 215 mm x 102.5 mm x 65 mm (length x depth x height). 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. 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). Cement-rice husk ash blended masonry mortar was developed with 75% cement and 25% rice husk ash. Size of brick =230×115 ×75 mm. Hence, a standard dimension is determined for various brick works. This gives a ratio of 3:2:1, meaning that: 1. Save my name, email, and website in this browser for the next time I comment. Mortar joints should not exceed 6 mm or 0.5 inch in thickness. Minimum thickness of mortar or grout between brick and reinforcement: 1/4 in. However, if bricks are small, a higher quantity of mortar is required; due to this fact, a normal dimension is set for various brickwork. In Pakistan, with mortar and center to center the standard size of brick is 9 x 4.5 x 3 inches. the height of each course in case of a brick size 230x110x75 mm, this is 110 mm plus mortar thickness) such that the shinner and rowlock are visible on the face of masonry as shown in the figure. What is the thickness of wall? Bigger bricks are sometimes used for extra economical laying and as a design characteristic either by themselves or mixed with smaller bricks.

In the table below, we have given the standard sizes of different brick as follows: In UK, the size and width of common brick had remained constant over the centuries, however, the depth is greater than about two inches (about 51 mm) or smaller than two and a half inches (about 64 mm). 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. “In England, the length and width of the common brick has remained fairly constant over the centuries but the depth has varied from about two inches (about 51 mm) or smaller in earlier times to about two and a half inches (about 64 mm) more recently. The standard brick size of 240 x 115 x 57 mm with 10 mm thick horizontal and vertical mortar joints is preferable. The building code for weight-bearing brick walls calls for mortar to be no more than 3/8 inch thick. To choose the type of brickwork, you should consider the conditions of the building design. Actual size (or the specified size), is the real dimension of the brick. He also suggested possibly using firebrick type block which are not too thick. Some bricks are made with different work sizes. 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. (6.4 mm) bars may be laid in 1/2-in.
