Reinforcement
Selection of reinforcement is considered by their availability, easy handling, flexibility, spread ability etc. The selected reinforcements used in the study are as follows:
1) Chicken Mesh (Hexagonal Shape) 2) Sand Mesh (Hard Type) 3) Sand Mesh (Smooth Type)
Chicken mesh is a low carbon content steel. The wire size is 0.2 mm and distance between two wires in hexagon in 15mm. In sand mesh (hard type) the wires are hard and size of wire is 0.25 mm running both ways making space of 2 mm square. But in sand mesh (smooth type) the wires are smooth and flexible. The reinforcement mesh which was cut slightly less than the brick size is placed at the predetermined height. Another installment of soil paste was filled. The procedure is continued for the required number of reinforcement layers. Top soil should be trimmed and mould is lifted up by leaving two bricks on the floor. Similar procedure is followed for more number of bricks by the side of prepared bricks. For un-reinforced bricks only soil paste was pressed without reinforcement and bricks were prepared.
