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 BRICK EARTH FORMED IN KILNS CONCRETE

3. KINDS OF TILES MAINLY OF THREE KINDS ROOFING TILES FLOORING OR PAVING TILES 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

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.

11. 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.

12. 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.

13. 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.

14. 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.

15. 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.

16. 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.
