Water Absorption Test For Ceramic Tiles

This is where porcelain tile is generally categorized.

Water absorption test for ceramic tiles.

Water absorption m2 m1 m1 100. Then it is weighed again. Lcs laboratory offers laboratory testing of water absorption bulk density apparent porosity and apparent specific gravity of ceramic and glass tiles. 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.

In this test 5 identical tiles are tested for their ability to retain water inside the open pores. Porcelain tile 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. The boiling method is used to classify the ceramic tiles and involves drying the tiles out and then boiling them in water for 2 hours followed by cooling to room temperature over a four hour period. For each tile calculate the water absorption in percentage to the first decimal place of the dry mass using the following formula.

If water is absorbed quite quickly the tile is considered to be normal absorbent type. Reflecting the density of the tile body ceramic tiles are also classified by their water absorption rate apart from the resistance to wear and tear. Impervious extremely dense tile with water absorption of 0 5 percent or less. Where m1 mass of the dry tile in g.

If water is still on tile back and takes time to be absorbed the tile is considered to be low absorbent type. M2 mass of the wet tile in g.
