THIS PPT COVERS ABOUT TILES,ITS TYPES AND ITS PROPERTIES. ROOFING TILES: PLAIN TILES,PAN TILES,POT TILES , ALLAHABAD TILES, MANGALORE TILES , CONCRETE ROOFING TILES . FLOORING TILES AND DRAIN TILES.

1. TILES
TOPICS TO BE COVERED
• TILES
• TYPES OF TILES
• PROPERTIES OF TILES
PRESENTATION BY
UTKARSH JAIN

2. TILES
• ARE THIN SLABS
• USED FOR COVERING ROOFS,FLOORING OR FOR MAKING DRAINS
• FORMED OF
I. BRICK EARTH FORMED IN KILNS
II. CONCRETE

3. KINDS OF TILES
• MAINLY OF THREE KINDS
1.ROOFING TILES
2.FLOORING OR PAVING TILES
3.DRAIN TILES

4. ROOFING TILES
• MAY BE FLAT LIKE SLATES OR MAY MADE OF DIFFERENT SHAPES.
• SOME COMMON VARIETIES

5. ROOFING TILES (VARIETIES)
•PLAIN TILES
• MESURES ABOUT :25 X 15 CM TO 28 X 18 CM
• THICKNESS : 10 – 17 CM
• HAVE CONTINUOUS PROJECTION AT ONE END OR TWO SMALL
PROJECTING RIBS.
• NIBS : NOT LESS THAN 2 CM WIDE & 1 CM DEEP.
• CAMBER : B/W 5 -10 MM FOR HAND MADE.
• CAMBER : MAY BE REDUCED FOR MACHINE MADE

7. ROOFING TILES(VARIETIES)
•PAN TILES
• ARE CURVED IN SECTION
• 33 – 38 CM LONG & 23 – 28 CM WIDE.
• MOULDING IMPLEMENTS : MOULD, HORSE ,BOW AND STRIKE
• BALL OF PREPARED CLAY IS PRESSED WELL TO FILL MOULD WELL.
• SURPLUS EARTH IS CUT WITH BOW AND REMOVED.

8. ROOFING TILES (VARIETIES)
•PAN TILES (CONTINUED)
• STRIKE IS PASSED OVER WET TOP OF TILE IN MOULD.
• DONE MANY TIMES TO RENDER TOP SURFACE OF TILES SMOOTH.
• TILE , THEN REMOVED AND PLACED OVER ALERADY BURNT TILE TO
DRY.
• AFTER LITTLE DRYING IT IS PLACED ON CURVED TOP OF HORSE AND
PRESSED.
• THIS MAKES TILE CURVED.

9. ROOFING TILES(VARIETIES)
•PAN TILES (CONTINUED)
• AFTER ANOTHER 5 – 6 HOURS OF DRYING TILE IS AGAIN SHAPED AD
EDGES ARE TRIMMED.
• ASH IS SPRINKLED BEFORE EVERY USE TO PREVENT CLAY FROM
STICKING.

11. ROOFING TILES (VARIETIES)
•POT TILES
• SEMICIRCULAR IN SECTION & TAPER ALONG LENGTH.
• DIAMETER : 23 CM AT LARGER END & 20 CM AT SMALLER END.
• ROWS OF THESE TILES : LAID WITH CONCAVE SIDE UP.
• ROWS OF SAME TILES WITH CONVEX SIDE UP : LAID TO COVER EDGES
OF EVERY PAIR OF PREVIOUSLY LAID TILES.

13. ROOFING TILES (VARIETIES)
•ALLAHABAD TILES.
• CONSISTS OF TWO SET OF TILES.
• LOWER ONES ARE FLAT WITH UPTURNED SIDES.
• END WIDTH REDUCE FROM 27 -23 CM & LENGTH IS ABOUT 38 CM.
• OVER TILE IS HALF ROUND IN SECTION.
• TAPERS : 16.5 -12 CM IN DIAMETER.
• TAPER ALLOWS TILE IN NEXT COURSE TO FIT IN.

14. ROOFING TILES (VARIETIES)
•ALLAHABAD TILES (CONTINUED)
• HALF ROUND TILES : MOULDED ON POTTERS WHEEL.
• TWO LONGITUDNAL CUTS ARE GIVEN IN CYLINDER ON HALF WET
CONDITION.
• AFTER BURNING THESE CUTS MAKE IT EASY TO BREAK INTO TWO
SEMICIRCULAR PIECES.

16. ROOFING TILES (VARIETIES)
•MANGALORE TILES
• FLAT PATTERN TILES.
• HAVE SUITABLE KEY PROJECTION.
• APPROX 16 TILES ARE REQUIRED TO COVER 1 SQUARE METRE ROOF.
• FOR DETAILS REFER IS : 654 – 1972.

18. ROOFING TILES(VARIETIES)
•CONCRETE ROOFING TILES
• COULD BE MADE OF ANY SHAPE , COLOUR , SIZE.
• MADE OF CEMENT CONCRETE.
• ARE MORE STRONG , DURABLE AND WEATHER RESISTANT.

19. FLOORING TILES
• USUALLY THICKER THAN ROOFING TILES.
• THICKNESS : B/W 15 – 30 MM.
• SHAPE : SQUARE , HEXAGONAL OR ANY OTHER GEOMETRICAL SHAPE.
• TILES MAY ALSO BE COLOURED.
• CLASSIFIED INTO CLASS I , CLASS II AND CLASS III TILES.
• MAX. WATER ABSORPTION % ARE 10 , 19 AND 24.
• MIN. FLEXURAL STRENGTH KG/CM ARE 6 , 3.5 , 2.5 RESPECTIVELY.

21. DRAIN TILES
• CURVED TILES MADE OF VARIOUS SHAPES AND SIZES.
• SHOULD SUIT THE WORK FOR WHICH IT IS USED.
• TILES SHOULD BE GLAZED FOR SEWAGE CARRYING DRAINS.

23. PROPERTIES OF TILES
• SHOULD BE OF REGULAR SHAPE AND SIZE.
• SHOULD BE FREE FROM TWISTS, CRACKS AND FLAWS.
• SHOULD BE WELL BURNT AND OF UNIFORM COLOUR.
• MUST GIVE CLEAR RINGING SOUND WHEN STRUCK.
• BROKEN SURFACE MUST SHOW AN EVEN AND COMPACT STRUCTURE.
