Maximum water absorption percentages in case of these are 10 19 and 24 respectively.
Properties of clay roof tiles.

Clay roof tiles are the perfect solution for preventing insects like masonry bees from tunnelling and as long as you use a quality clay tile they are resistant to thermal damage from freezing and thawing.
This study explores the possibility of substituting clayey raw materials using ceramic sludge in clay roof tile production.
Bulk density reduces with increasing the sludge content which is a favorable property of roof tiles.
It should not deform shrink when drying swell when wet or crack when under prolonged stress.
Clay roof tiles are fire proof.
Since clay is a naturally occurring material clay tiles maintain their original color for years despite being subjected to weather conditions.
The tile specimens were manufactured in an industrial scale plant by replacing clay with ceramic sludge.
Another advantage is that it is available in a variety of shapes sizes and colors unlike regular shingles adding more character and interest to the appearance of your home.
Here are some of the most common shapes and types of clay roof tiles which you must know.
Plain tiles hollow tiles or overlapping tiles monk nun tiles over and under tiles flat tiles pantiles.
Uneven temperatures in the kiln and the nature of the hand making process also contributed to variations in shape and form and the quality of the clay resulted in rough and therefore textured surfaces.
Cedar shakes shingles.
Due to the firing flat tiles would come out slightly convex and this added to their character.
For details refer to is.
Clay replacement up to 20 is acceptable satisfying water absorption and penetration in standards.
0 10 15 20 and 25 by weight.
Any roofing material that can last for over 100 years has to be good.
Ceramic finishes offered by many clay roof tile manufacturers are baked in high temperatures of around 2 000 degrees creating a non porous finish that will virtually last forever.
Concrete clay roof tiles.
Bricks blocks roof tiles and pavers made from clay are dimensionally stable meaning that structural defects during construction are unlikely when the products are installed correctly.
Transverse breaking strength was optimum at 20 sludge indicating 22 9 increment compared to the conventional tile.
Minimum average flexural strength kg cm width in respect of these is 6 3 5 and 2 5 respectively.
Clay roof tile popularity soared after the great fire of london.
