Classification of Bricks Based on Manufacturing Method. On the basis of manufacturing method bricks are of the following kinds: Extruded Brick: It is created by forcing clay and water into a steel die, with a very regular shape and size, then cutting the resulting column into shorter units with wires before firing. It is used in constructions with limited budgets.
20mm which is placed on raw brick during moulding.It serves two purposes. 1.It indicates the trade name of the manufacturer . 2.In brick work, the bricks are laid with frog uppermost. It thus affords a key for mortar when the next brick is placed over it. The ground moulded bricks of better and with frogs on their surface are made by quality
process is non-destructive in that the bricks are merely baked at low temperature, sufficient to melt the waste plastic that gets diffused within the body of the bricks. The compressive strengths after addition of waste plastic is same as normal brick strength. And also reduce the water absorption capacity
