Brick

>> Clay is the most common material, with modern clay bricks formed in one of three processes - soft mud, dry press, or extruded.
 * What are they made of?
 * "Bricks" for building may be made from clay, shale, soft slate, calcium silicate, concrete, or shaped from quarried stone. However, true bricks are ceramic, and therefore created by the action of heat and cooling.
 * What are they used for?
 * Bricks are used for building and pavement


 * How many types of brick are there?
 *  Brick masonry units may be solid, hollow, or architectural terra cotta. All types can serve a structural function, a decorative function, or a combination of both. The various types differ in their formation and composition.
 * What is the meaning of brick laying techniques


 * It is the procedure of laying bricks in certain ways in order to make a structure out of bricks. It is about how every brick fits in with another to form a compound unit
 * Describe 2 brick laying techniques

There are three tipes of bonds: structural bond, mortar bond, or pattern bond.


 * Overlapping (interlocking) the masonry units.
 * Embedding metal ties in connecting joints
 *  Using grout to adhere adjacent wythes of masonry. Mortar bond refers to the adhesion of the joint mortar to the masonry units or to the reinforcing steel


 * What are their advantages and disadvantages?

 Advantages: they are fireand weather resistant, they are easy to transportate, in production and in laying. <span style="font-family: 'Comic Sans MS',cursive;"> Disadvanges: they can only be used in conjuction with mortar, since they are too small, too light an too irregular to be stabilized by weight.

I think bricks are a great choice for building. They have more advantages than disadvantages. They are weather resistant and also very easy to produce, transport and lay. Finally, bricks vary in shapes so that they may fit certain structures and be more resistant.media type="file" key="Brick.wav" width="300" height="50"
 * My thoughts on the use of brick in constructions and public spaces:**

 * Reading:**
 * <span style="color: black; font-family: 'Times New Roman','serif';">Brick __compares__ favorably with stone as a structural material for its fire-and-weather resisting qualities and for the ease of production, transportation, and laying. ||
 * __<span style="color: black; font-family: 'Times New Roman','serif';">fire-and-weather resisting … __ ||
 * <span style="color: black; font-family: 'Times New Roman','serif';">(__for example__, wedge-shaped bricks are sometimes employed in arch construction and bricks with rounded faces in columns). ||
 * Bricks may be used in construction only in conjunction with mortar, __since__ the unit is too small, too light, and too irregular to be stabilized by weight. ||
 * <span style="color: black; font-family: 'Times New Roman','serif';">The size of bricks is limited by the need for efficient drying, firing, and handling, but shapes, along with the techniques of bricklaying, have varied __widely throughout history__. ||
