Laboratory reports individual test results for each tile as well as the average of 5 measurements.
Water absorption in ceramic tiles.
According to the industry group that decides whether a tile is porcelain or ceramic everything boils down to whether the tile can meet a set of highly controlled water absorption criteria.
Absorbent value more than 3 e g.
Wet areas such as a shower or steam room should have porcelain tiles.
Both ceramic tile and porcelain tile usually receive a surface glazing that makes them hard to distinguish from one another.
Typical water absorption on non porous tiles and glass tiles is 0 1 0 5 while the porous products can exhibit water absorption in the range 9 15.
Ceramic will absorb the moisture like a sponge but will only bead up on porcelain.
Ceramic tile that is fire glazed is 100 perfect for indoor floor use.
The water absorption rate is directly related with the suitability of the various types of tile for interior or exterior applications.
High absorption more than 7 water absorbed.
Tiles can be differentiated according to their water absorption into 3 types as follow.
If you take the 2 tiles flip upside down and sprinkle water on them.
Not suitable for outdoor use or for rooms.
Homogeneous tile granite tile.
Absorbent value between 0 5 3 e g.
It can directly describe the density of the product and affect the moisture resistance of the.
Objective determination of water absorption and bulk density of all ceramic tiles apparatus oven capable of maintaining temp of about 1100c balance accurate to 0 01 of the mass of test specimen water bath desiccators chamois leather wire basket preparation of test sample a test sample consists of 10 numbers of whole tiles.
Rustic tile glass mosaics resin mosaic.
Water absorption w a a tile s rate of water absorption.
Weight of water absorbed as percentage of tile weight.
For exterior applications the selected tiles must have a very low water absorption rate as close to an impervious rating as possible especially in climates subjected to rainfall freezing and thawing cycles.
Porcelain tiles have a far lower water absorption rate than glazed stoneware tiles for example.
A mere 0 5 in the case of porcelain tiles compared with 6 for stoneware ones groove by keraben.
Absorbent value less than 0 5 e g.
