Brick masonry

Brick masonry is a unified mass obtained by systematic arrangement of laying bricks and bonding together with mortar. Brick is  a building unit of hard inorganic clay material of size which can be  conviently handled. The brick masonry is used in foundations, walls,  columns, buttresses, retaining structures window sells, jambs, corbels,  copings ornamental brickwork, circular brickwork, fire places, flumes,  
tall chimneys, cavity walls, thresholds, culverts, steps, floors, arches etc.
The strength of brick masonry works depends upon the quality of bricks
and type of mortar used.
Generally mortars are following types used for brick masonry
(i) Mud mortar 
(ii) Cement mortar 
(iii) Cement lime mortar 
(iv) Lime surkhe 
General principles in brick masonry construction:
1. A good brick masonry should utilize bricks, which are sound, hard, well burnt and tough with uniform colour, shape and size.  
2. The bricks should be compact, homogenious, free form holes, cracks, flaws, air-bubbles and stone lumps and soaked in water  for atleast two hours before use.  
3. In the brickwork, the bricks should be laid on their beds with the
frogs pointing upwards.
4. The brick courses should be laid truly horizontal and should have truly vertical joints.  
5. As far as possible the use of brick – bats should be discouraged.
6. As far as possible the brick wall should be raised uniformly less than 1.5m in day with proper bond.  
7. When the mortar is green the face joints should be racked to a depth of 12 to 19mm in order to have a proper key for plastering  
or pointing.
8. In order to ensure continuous bond between the old and the new, the wall should be stopped with a toothed end.  
9. Finished brickwork should be cured for a period of 2 to 3 weeks for lime mortar and 1 to 2 weeks for cement mortar.  
10. In order to carryout the brickwork at higher level, a single scaffolding is used.

Formwork

             Formwork is the term used for the process of creating a temporary mould into which concrete is poured and formed. formwork it is a temporary support. 1)This is temporary casing is known formwork or forms or shuttering. 2) It becomes sufficiently strong to support its own weight. 3) Traditional formwork is fabricated using timber, but it can be also constructed from Steel, glass fibre, reinforced plastics and other material. specification:- 1. Capable of resisting hydrostatic pressure of the wet concrete. 2. Join should prevent leakage of cement grout. 3. High quality workmanship and inspection necessary. 4. As light weight has possible. 5. Material used be suitable for reuse. 6.Formwork base or soffit must be capable of resisting the initial dead load of wet concrete. 7.Strong enough to withstand dead and live loads. 8.Capable of retaining its shape by being efficiently propped and braced horizontally and vertically...

It generally consist of small wedge-shaped unit which are join together with mortar. 3.The archers made of steel and R.C.C are built in single unit without the use of wedge-shape unit and they are used for the bridge construction. Types of arches:- 1. Flat arch 2. Segmental arch 3. Semi-circular arch 4. Semi-ecliptical arch 5. Inverted arch 6. Pointed arch 7. Relieving arch 8. Horse-shoe arch 9.Silted arch 10. Venetian arch 11. Florentine arch  Flat arch:- 1. The apparent shape of this arch is flat. 2. The Skewback form is angle of 60 degree with the horizontal. 3. An equilateral triangle is formed with one side has intrados  4. The extrados is kept perfectly horizontal or sometimes ,in order to prevent it from becomes hollow when arch settle. 5. The flat arch are found to be comparatively weak and they are used only for light load and for span up to 1.5 m. Segment...
