15. ADVANTAGES OF BRICKS

16. 1.Strong and Durable 2. Low Maintenance

17. Thermal Performance Brick buildings, particularly double brick, have excellent thermal mass

18. Design Flexibility Fire Resistance

19. PROPERTIES OF BRICKS

20. Feels Hard - moulded clay is baked at a very high temperature to form bricks Roughish- and looks dull Dry Easy to handle - bricks are all the same regular shape and size making them easy to carry and build

21. Takes Bonding - they make a strong structure when bonded together Resistance Cold - brick keeps in heat (insulates) Electricity - they will not carry an electrical charge Weather - bricks are hard-wearing and reasonably weatherproof Fire - they will blacken but not burn.

22. Changes If frozen - bricks are not waterproof and will slowly absorb water - if the water freezes and therefore expands then the ice will lead to the bricks flaking and breaking up  If  knocked - bricks are brittle and will shatter - some bricks are stronger than others depending on the sort of clay used

23. ` MANUFACTURING O BRICKS DEMERITS OF BRICKS

24. 1.Continuing use of clay bricks in construction industry will lead to extensive loss of fertile top soil. This could be a devastating environmental hazard. 2.High demand for clay bricks would result in price hike of clay bricks.

25. 4.Burnt clay bricks are manufactured using old outdated technology and no quality testing facilities are available at manufacturing site. Most bricks which are manufactured using outdated technology are inferior in quality with low compressive strength. They are not suitable for multi-storey buildings. 5.Modern Fly ash bricks are manufactured using high end pre-programmed hydraulic machines. Bricks from these machines are tested for its quality and durability.

26. MANUFACTURING OF BRICKS

27. In this step the soil is excavated in steps and then laid on leveled ground. 2.High demand for clay bricks would result in price hike of clay bricks.

28. 1. Preparation of brick clay or brick earth In this step the soil is excavated in steps and then laid on leveled ground. 2. Moulding of Bricks Bricks are moulded in many ways depending on the quality of the product to be made. Generally the moulding is done in the following two ways Hand moulding Machine moulding

30. 3. Drying of Bricks Drying is usually done by placing the bricks in sheds with open sides so as to ensure free circulation of air and protection from bad weather and rains. The drying period usually varies from 7 to 14days. 4. Burning of the Bricks It is the very important step in manufacture of bricks. Bricks may be burnt by two distinct methods given below. clamp burning kiln burning
