Floor Tile Water Absorption

Absorbent value between 0 5 3 e g.

Floor tile water absorption.

Suitable for all interior and exterior uses. All grouts except epoxies will allow some moisture absorption. In fact it tells us that the ceramic. Low water absorption enhances durability especially in circumstances where tiles may be subjected to heavy loads and or high levels of foot traffic.

Glazed tiles are resistant to water at the tile surface but susceptible at the edges. 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. The water absorption percentage reflects the density of the tile body. Only vitreous and impervious tiles should be used outdoors or in.

This may seem like just another characteristic on the list of specifications but it is more than this. Homogeneous tile granite tile. Porcelain tiles have a far lower water absorption rate than glazed stoneware tiles for example. Tiles are classified according to water absorption percentages as follows.

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. 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. Absorbent value more than 3 e g. Rustic tile glass mosaics resin mosaic.

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. 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. 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.

Tiles can be differentiated according to their water absorption into 3 types as follow. 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. 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.

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.
