BRICK MASONARY



1 . Stretcher : 
  • Stretcher is the longer face of the brick ( i.e. 19 cm × 9 cm )
  • A course of bricks in which all the bricks are laid as stretches on facing is known as a stretcher course or stretching course 
2. Header : 
  • Header is the shorter face of the brick ( i.e. 9 cm × 9 cm ) . A course of bricks in which all the bricks are laid as headers on the facing is known as header course or heading course . 
3. Lap : 
  • Lap is the horizontal distance between the vertical joints of successive bricks courses 
4 . Prepand : 
  • Perpend  is an imaginary vertical line which includes the vertical joint separating two adjoining brick 
5 . Bed : 
  • Bed is the lower surface ( 19 cm × 9 cm ) of the brick when laid flat 
6 . Closer :  closer may be of various types 
  • closer it is a portion of a bricks with the cut made longitudinally, and is used to close up bond at the end of course 
  • it helps in preventing the joints of successive sources ( higher or lower ) to cone iin a vertical line
6 . Queen - closer : 
  • Queen - closer it is a portion of bricks obtained by cutting A brick lengthwise into two portions .thus it is a brick which is half as wide as the full brick 
  • it also known as queen queen closer half 
  • if a queen closer is broken into two pieces , it is known aa queen closer quarter , such a closer is thus a brick piece which is one quarter of the brick size .
8 Bevelled close  : 
  • it is a special form of a king closer in which the whole length of the brick ( i .e . stretcher face ) is bevelled in such a way that half  width is maontmaint at one end and full width is maintained at the other 
9 . king closer : 
  • it is the portion of a brick which is such cut that widthof one its end is half that of a full brick while the width at the other end is equal to the full width 
  • it is obtained by cutting the triangular pices betwee  the center of one end and the centre of the other side 
  • it has half - header and half - stretcher face 
10 mitred closer : 
  • mitred closerit is a portion of a brick whoes one end is cut splayed or mitred for full width 
  • Angle of splay may very form 45° to 60° 
  • one longer face of the mitred closer is of full length of the brick while the other face is smaller in length
11 . Bat : 
  • it is the portion of the brick cut acress the width  
  • A bat is smaller in length then the full brick   
  • if length of the bat is equal to half the length of the original brick, it is known as half bat 
  • A three quarter - bat is the one having its length equal to three quarters of the length of a full brick 
  • if bat has its width bevelled . it is known is bevelled bat 
12. Arris : 
  •    it is the edge of a brick 

13 . bull Nose :

  • it is a special moulded bricks with one edge rounded or with two edge rounded 
  • these are used in copings or in such positions where rounded corners are perferred to sharp arises

WHAT IS SLUMP TEST

Image
Slump test is one of most extensively used test all over the world  Slump test does not measure workability of concrete , although it gives a measure of consistency , but is very useful in detecting variation in uniformity of mix of given nominal proportions  Dimensions of the mould are, bottom diameter =200 mm top diameter =100mm and hight = 300 mm  Mould is filled in with fresh concrete in four layers , each layers of approximately one - quarter of the height of the mould and tamped with 25 strokes of the rounded end of the tamping rod ( dia 16 mm and length 600 mm)  Strokes are distributed in a uniform manner over the cross section and for the second and subsequent layers should penetrate into the underlying layer  After the top layer has been rodded, the concrete is struck off level with a trowel or the tamping rod such that the mould is exactly filled .  Mould is removed immediately by raising il slowly and carefully in a vertical direction   It allows the concrete to sub

WARKABILITY

Warkability is defined as the property of concrete which determines the amount of useful internal wark necessary to produce full compaction  In simple words it can also be defined as the ease with which concrete can be compt 100% with regard to made of compaction and place of deposition  A concrete which can be readily compacted is said to be workable , but to merely say that warkability determines the ease of placement and the resistance to segregation is to loose a description of this vital property of concrete  Desired warkability in any particular case would depend on the means of compaction available likewise ,a warkability suitable for mass concrete is not necessary sufficient frothing , inaccessible ,or heavily reinforced section  It should be noted at warkability is different form consistency . consistency indicates fluidity or mobility  Concrete with high consistency may not be workable for a particular job and concrete having same consistency many very in warkability

TYPES OF RAILS

Image
1. Double headed rails ( D.H. rails) These rails wear used in the beginning  The idea was , when the head will wern out in course of time, the rail can be inverted and reused  In the lower part the inundations wear so formed that smooth running over that surface at the top was impossible , so idea got failed  2 . Bull headed rails ( B.H. rails ) :  In B. H. Rails the head was made a little thicker and stronger then the lower part  3 . Flat footed rails ( F.F. rails ) :  F.F. rails are also called vignole's rails after the name of the inventor  Bearing plates are used between the sleeper and rail at rail joints  These rails are designated by wt of rail per unit length  52 kg/ m or 52 MR and 60  kg / m or 60 MR F.F. rails are used in India  52 kg rail is suitable upto speed of 130 kmph and 60 kg rail is suitable upto speed of 160 km/h
