Water absorption m2 m1 m1 100.
Water absorption test for ceramic tiles.
There are 2 methods to determine the water absorption of the ceramic 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.
Impervious extremely dense tile with water absorption of 0 5 percent or less.
This is where porcelain tile is generally categorized.
Where m1 mass of the dry tile in g.
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.
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.
If water is absorbed quite quickly the tile is considered to be normal absorbent type.
For each tile calculate the water absorption in percentage to the first decimal place of the dry mass using the following formula.
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.
According to china s national standards for testing tiles tiles according to the different water absorption divided into porcelain brick water absorption e 0 5 fine stoneware tile water absorption 3 e 6 stoneware brick water absorption 6 e 10 ceramic brick water absorption of 10 or more and so on.
In this test 5 identical tiles are tested for their ability to retain water inside the open pores.
Lcs laboratory offers laboratory testing of water absorption bulk density apparent porosity and apparent specific gravity of ceramic and glass tiles.
M2 mass of the wet tile in g.
