Week 1 brick

  1. 1. brick C A 1 0 4 I materials for building construction june 2012 nur shuhada bt hanapi
  2. 2. 1.0 brick manufacturing flow chart of clay masonry units
  3. 3. 1.0 brick common brick  Do not have proper finishing on its surface  Suitable for construction which needs plastering such as partition wall  The price is cheaper compare to facing brick and engineering brick  The colour of the brick can change due to the weathering effect  Suitable for general building work, but have no special claim to give an attractive appearance
  4. 4. 1.0 brick facing brick  Has attractive finishing with uniform colour  Suitable for construction that do not require plastering  It is durable to weather ; rain, frost, etc  Produced using pressed process  Facing brick is more dense to carry applied load
  5. 5. 1.0 brick Sultan Abdul Samad Building The Old General Post Office
  6. 6. 1.0 brick engineering brick  Produced from selected clay  Engineering brick is more dense because its function is to carry applied load  Strong  Difficult to absorb water  Suitable to be used for several purpose Retaining wall Load bearing wall Sewer and manhole Bridge construction Other purpose that may exposed to chemical reaction
  7. 7. 1.0 brick other brick  Other than clay bricks mention above, there are also: Fire brick Sand lime/ calcium silicate brick Concrete brick Cement brick Marl brick Special purpose brick Shale brick Glazed brick
  8. 8. 1.0 brick brick dimension bricks do not have specific dimension because it shrink during drying and burning process,but it can be measured into the standard size of modular brick
  9. 9. 1.0 brick cut brick Bricks are often cut into different shapes to fill in spaces at corners and other places where a full brick will not fit
  10. 10. 1.0 brick mortar  mortar is a plastic mixture of cement or lime or a combination of both, with sand and water  used as a bonding agent in masonry construction  ratio for mortar mixture •1:3 (general brickwork or plastering) •1:4 (for engineering brickwork)  Types of mortar • Lime mortar • Cement mortar • Coloured mortar
  11. 11. 1.0 brick lime mortar  used widely before the existing of cement mixture of lime, sand and water rarely used because of its: •slow rate of hardening •low compressive strength •easy to absorb water
  12. 12. 1.0 brick cement mortar  Made by mixing Portland cement, sand and water  Mixture ratio (cement: sand) -1:3 / 1:4  High compressive strength compare to lime mortar  High rate of hardening  Suitable for all brick bonding and damp areas  Admixture can be added to improve the quality
  13. 13. 1.0 brick coloured mortar  Made by mixing coloured cement, sand and water  High rate of hardening  Suitable for all brick bonding and to give special effect
  14. 14. 1.0 brick brick terminology The creative use of brick bonding with or without contrasting or complementary brick colours can have a dramatic effect on the appearance of a building Course- a row of bricks Header- short side of the brick faces out Stretcher- long side of the bricks faces out Stretcher Header
  15. 15. 1.0 brick terminologies in brick lying
  16. 16. 1.0 brick brick bonding BRICK BONDING RULES  Avoid horizontal/ continuous jointing x  Bonding must overlapping each other ¼ or ½ should be used BRICK BONDING PRINCIPLES  Provide stability to a masonry wall   Maintain the aesthetic value  The wall should not collapse
  17. 17. 1.0 brick brickwork bonds Types of brickwork bonds that commonly used a. Stretcher bond b. Header bond c. English bond d. Flemish bond
  18. 18. 1.0 brick Stretcher Bond Stretcher Bond is the easiest bond to lay and minimises the amount of cutting required Used for ½ brick wall Not suitable to be used for load bearing wall Suitable to be used for general work such as partition wall
  19. 19. 1.0 brick Header Bond Header bond is not used as often as stretcher bond, but is equally simple Its impractical for single skin walls 1/3 bat brick used at the end of the layer Suitable to be used for load bearing wall, arches, etc
  20. 20. 1.0 brick English Bond  Consist of alternate courses of stretchers and headers  This is one of the strongest brickwork bond patterns
  21. 21. 1.0 brick Flemish Bond  Flemish bond features alternating headers and stretchers within the course  This is a more decorative pattern than English bond, especially if the headers use a differently coloured brick but a bit weaker than English Bond
  22. 22. 1.0 brick brick jointing & brick pointing  Both term used for the finish given to both; the vertical and the horizontal joints in brickwork irrespective applied on facing brickwork • The finish given to the joints when carried out as the work proceeds BRICK • Purpose: produce a neat and good brickwork JOINTING • Advantages: practical, strong, faster and economical • Disadvantages: hard to get the uniformity of the colour and cannot be done during rainy day • Is the finish given to the joints by racking out to a depth of BRICK approximately 15mm and fills in on the face with a hard- setting cement mortar POINTING • Can be applied to both; old and new • Purpose: to make future plastering work easier
  23. 23. 1.0 brick Brick jointing
  24. 24. 1.0 brick Brick pointing New New old mortar old mortar mortar mortar Beaded Point Cantilever Point
