This document provides information on bricks, including their definition, size, constituents, manufacturing process, types, bonding, and advantages and disadvantages. Bricks are clay construction materials that are durable and low-cost. They are standardized at 9 1/2 x 4 1/2 x 2 3/4 inches in Bangladesh. Bricks are made through processes of preparation, molding, drying, and burning. Their quality depends on factors like composition, strength, and water absorption. Bricks are used in various bond patterns and structures.
Brick masonry provides fire resistance, durability, and strength due to its homogeneous mass when bricks are laid in mortar. There are different types of bonds that provide varying strength, with English bond being the strongest. Bricks must meet quality standards like being uniformly shaped, emitting a clear ringing sound when struck, and having low water absorption. Proper tools and techniques are used to lay bricks in bonds with headers, stretchers, and closures to reinforce the wall structure. Brick masonry walls can be constructed using various bonds and have advantages of low cost and availability of materials.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

3. Definition Of Brick
A brick is an important construction material generally
available in rectangular shapes manufactured from
clay. They are trendy from the olden days to modern
days because of low cost and durability.
Size Of Brick
In Bangladesh, standard brick dimension is
9 1⁄2 x 4 1⁄2 x 2 3⁄4 inch.
For more country Brick size :
Country Brick size
London 215mm x 102.5mm x 65mm
USA 194mm x 92mm x 57mm
Australia 230mm x 110mm x 76mm
Romania 240mm x 115mm x 63mm
Russia 250mm x 120mm x 62mm
Sweden 250mm x 120mm x 62mm

4. Silica (sand) – 50% to 60% by weight
Alumina (clay) – 20% to 30% by weight
Lime – 2 to 5% by weight
Iron oxide – ≤ 7% by weight
Magnesia – less than 1% by weight
Constituent Of Brick
Function Of Constituents Of Brick
Silica prevents the cracking, shrinking, and
warping of raw bricks. It imparts a uniform
shape to the bricks. But excess silica makes
the bricks brittle
Alumina imparts plasticity to the earth so that
it can be molded. But if it is excess raw bricks
shrink and wrap during drying and burning.
Lime for binding particles together.
Iron oxide imparts color and gives strength
and hardness to bind particles.
Magnesia decreases shrinkage and gives a
yellow tint to brick
5. Qualities Of A Good Brick
Brick earth should be free from pebbles (kankars), stones, organic matter, saltpeter
(potassium nitrate) and other harmful chemicals.
A good brick should have a uniform size with plain and rectangular surfaces.
The shape of a brick should be uniform.
A good quality brick should have a proper frog.
The good bricks should have a pre-compacted and uniform texture.
The compressive strength of brick depends upon the composition of the clay and
degree of burning.
Bricks should be sufficiently hard. No impression should be left on the surface of a
brick when it is scratched with fingernails.
Water absorption of a good brick should not exceed 20 % of its dry weight when
immersed in water for 24 hours.
When the brick is struck with a hammer or with another brick, it should give a
metallic ringing sound.

7. Types Of Bricks
· First-class bricks
These bricks are moulded into table-
moulding and burnt in large kilns. As the result these bricks have
standard shapes, sharp edges and have smooth surface. These bricks
are more durable and have more strength. The first class bricks are
used for permanent structures.
· Second-class bricks:
These bricks are moderate quality bricks
moulded with ground-moulding process. These bricks are burnt in
kilns. As the ground moulding process is used they don't have
smooth surface and edges.
· Third-class bricks:
Third class bricks are used in temporary
structures as they have poor quality. These bricks are not suitable for
rainy areas. These bricks are ground-moulded and burnt in clamps.
The bricks have rough surface and edges are not proper.
· Picked bricks:
These types of bricks are also called rejected
bricks and are very similar in properties and quality to unburnt
bricks. They are over burnt and thus very weak and cannot be used
as a building blocks. They are of non-uniform shape, size, and color.

.Advantages Of Brick
Economical (Raw material is easily available)
Hard and durable
Compressive strength is good enough for ordinary construction
Different orientations and sizes give different surface textures
Very low maintenance cost is required
Demolishing of brick structures is very easy, less time consuming
and hence economic
Reusable and Recyclable
Highly fire resistant
Produces less environmental pollution during manufacturing
process
13. .Disadvantages Of Brick
Time consuming construction
Cannot be used in high seismic zones
Since bricks absorb water easily, therefore, it causes fluorescence
when not exposed to air
Very Less tensile strength
Rough surfaces of bricks may cause mold growth if not properly
cleaned
Cleaning brick surfaces is a hard job
Color of low quality brick changes when exposed to sun for a long
period of time
