Bricks definition, Advantage and disadvantage,Property of bricks and Bricks uses

 One of the oldest building material brick continues to be the most popular and leading construction material because of being cheap, durable and easy to handle and work with. Clay bricks are used for building-up exterior and interior walls, partitions, piers, footings, pavement and other load-bearing structures.

A brick is rectangular in shape and of the size that can be conveniently handled with one hand. Brick may be made of burnt clay or mixture of sand and lime or of Portland cement concrete. Clay bricks are commonly used since these are economical and easily available.

clay is plastic earth, is constituted largely of sand an alumina and may contain various quantities of chalk, iron oxide, magnesia, alumina etc.


Strength of bricks

Following factor affect the strength of brick 

    1 composition of brick earth.

    2 preparation of clay and blending of ingredients.

    3 Nature of moulding adopted.

    4 Care taken in drying and staking of raw bricks.

    5 types of kiln used including type of fuel and its feeding.

    6 Burning and cooling effect.

    7 care taken in unloading.

Advantage 

    1 Economical

    2 Very low maintenance cost is required.

    3 Massonery is easier, faster and stronger.

    4 Bricks have grater fir resistance 

    5 Better thermal insulation 

    6 It enhances good sound absorption. 

    7 It can be easily adapted to small and large scale structure to give pleasing appearance and texture.

Disadvantage

    1 Time-consuming construction

    2 Very less tensile strength.

    3 Rough surface of bricks may cause brick growth if not properly cleaned.

    4 Bricks absorbed water easily, therefore it causes fluorescence when not exposed to air.

Properties of Bricks

    1 Size and shape variations

    2 Colour

    3 Texture 

    4 Porosity

    5 Compressive strength

    6 Absorption 

    7 Fire resistance

Use

    1 Construction of the wall 



    2 Construction of flooring



    3 Construction or arches



    4 Construction of staircase



    5 Construction of the foundation

    6 Making of surkhi

    7 Construction of veneer wall

   A brick veneer wall is constructed by having a non-structural external layer, usually with bricks and it is backed by an air cavity. The innermost the element of this type of wall is structural can consist of wood, metal framing or masonry. A brick veneer construction has many advantages over solid masonry.

Concrete and its grde

  Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates (Crushed or natural stones) mixed with water which hardens with time. Portland cement is the commonly used type of cement for the production of concrete. The proportion of Concrete: The proportion of concrete depends upon 1.       cement, 2.       sand, 3.       aggregates and 4.       Water. A mixture of Portland cement and water is called a paste. So, concrete can be called a mixture of paste, sand and aggregates. Sometimes rocks are used instead of aggregates. The cement paste coat the surface of the fine and coarse aggregates when mixed thoroughly and binds them. Soon after mixing the components, hydration reaction starts which provides strength and a rock solid concrete is obtained. Materials are mixed in specific proportions to obtain the required strength.
