In fact it tells us that the ceramic.
Floor tile water absorption.
The water absorption percentage reflects the density of the tile body.
All grouts except epoxies will allow some moisture absorption.
Homogeneous tile granite tile.
Absorbent value between 0 5 3 e g.
Tiles can be differentiated according to their water absorption into 3 types as follow.
Water absorption astm c373 this is the measurement of density porosity and specific gravity as a tool for determining the degree of maturation of a tile or for determining structural properties that may be required for a given application.
For exterior applications the selected tiles should have a low water absorption rate especially in climates subjected to heavy rainfall and freezing and thawing cycles.
Water absorption is also directly related to the suitability for interior or exterior applications.
This may seem like just another characteristic on the list of specifications but it is more than this.
Tiles are classified according to water absorption percentages as follows.
Dense practically impervious tiles are highly unlikely to bend they are also highly resistant to liquid impregnation and subsequent staining consequently they are relatively easy to clean and.
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.
Glazed tiles are resistant to water at the tile surface but susceptible at the edges.
Suitable for all interior and exterior uses.
Low water absorption enhances durability especially in circumstances where tiles may be subjected to heavy loads and or high levels of foot traffic.
Porcelain tile has a water absorption rate of 0 5 percent or lower as defined by the american society for testing and materials astm section c373.
Rustic tile glass mosaics resin mosaic.
The water absorption rate is directly related with the suitability of the various types of tile for interior or exterior applications.
Water absorption en 99 iso 10545 3 astm c373 88 a tile s water absorption rate wa will tell you if the tile you re considering is the right tile to use in an outdoor or wet area.
The wa is determined by measuring the degree of internal porosity of the tile body and consists of boiling the tile in water and measuring its gain in weight.
Only vitreous and impervious tiles should be used outdoors or in.
Absorbent value more than 3 e g.
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.
To test this the fired tile is first weighed then it is boiled for five hours and left to sit in water for 24 hours.
