TILES• Tiles are thin slabs of low melting clays used for various

purposes in engineering constructions.• These give a very pleasing appearance and good service

properties. Some examples are– Roofing tiles – Flooring tiles– Wall tiles – Partition tiles

Roof Tiles• Various types of Roofing Tiles in common use are shown in

Fig. 2.16. (pp 33 to 36) • Roofing tiles have lost their importance due to

– Considerable Mass– Labor consuming manufacture– Erection and Drainage problems– Appreciable Transportation charges

FLOOR & WALL TILESFLOOR TILES• Floor tiles are extensively used in houses and industrial buildings.• These are Durable and Impervious to Water, resist Abrasion well and Wash

easily. • Raw mtrl for mfg Floor Tiles

– White burning Clays– Red burning Clays– Fire Clays– Shales

WALL TILES• Differ from Floor tiles principally in

– Design – Degree of Burning.

• Temperature control– Wall tiles are burned at a comparatively low temperature, – Glazed, and – Fired again in Muffle Kiln, at a still lower temperature

MANUFACTURING• Tiles are made in the same manner as Bricks, but are thinner and

lighter, so require greater care. • ***(If Question comes in Exams about Manufacturing of Tiles, you

will have to write the Process involved in Brick making and then add the following important pts.)

• These are manufactured – from a Clay Mass – with or without ADMIXURES of colouring impurities – by Moulding and – subsequent Burning until Baked, up to about 1300°C.

• The Clay should be – Highly Plastic with – Lean Admixtures and – Fusing agents to lower the Melting Point.

• Moulded in – Auger type m/c – Plunger type m/c

• commonly burned in Continuous Kilns.

1. For tiles also, Auger/Plunger type Plastic Moulding machines are used. 2. Shown below Is the drawing and cutting process for Bricks. 3. For Tiles, Drawing and Cutting process will be different.
