How To Lay Blocks/Bricks

Objectives
Blocks are laid to create wall. Wall in turn   are used to achieve the followings:
Load bearing
Partitioning of space
Create privacy
Define boundary
Create retention-as in retaining wall
Create visual obstruction
Modern block and bricks bare formed into tongue and groove shape at their  ends to  achieve firm grips. So as they are arranged linearly side by side, they are tongue and grooved into one another.
The special  arrangement of block and bricks to form wall is called inter bonding. This is the linear staggered  interlocking arrangement to provide lateral stability and resistance to side thrust
Blocks are usually hollow core with spaces and opening in them, while bricks are usually solid core, with no spaces in them.
Steps to lay Block and bricks
Basic Tools:
Hand trowel
Rubbing Board
Line
Plum and level
Range
Basic Materials.
Block/Brick
Cement
Coarse sand
Water
NB
Mix cement, sand, and water to form mortal ratio 1:8 of cement and sand.
Establish the whole length of the wall you are about to create
Place the mortal on starting point and at the ending point.
Position a block or brick at the starting and another block or brick at the end point with groove end facing the tongue of flat end.
Depending on the span or interval use either line of ranging pole to connect the two start and end block to ascertain their alignment
Employ the use of plum to check vertical alignment and horizontal level. You can adjust level with mortal or broken blocks.
Spread the mortal along the alignment part of the start and end block.
Lay the blocks or brick along the path with tongue and facing the groove/flat end.
Observe at least 40mm mortal joint gap in between each block.
Use the line and plum to check the alignment and levelto check the level.
Then fill the gap in between block with cement mortal, using hand trowel and scrubbing board.
Dress up the hand trowel
Repeat the process for next layer, but stagger the arrangement by ensuring the start block and end block do not fall exactly on the lower one to achieve bonding effect.
Do not lay beyond four layer consecutively in a single operation. This is necessary so that the dead weight of the of the block will not be too much for the wet mortal to bear, thereby causing instability.
