Water absorption in ceramic tiles.

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. Homogeneous tile granite tile. Absorbent value less than 0 5 e g. Tiles can be differentiated according to their water absorption into 3 types as follow.

Water absorption w a a tile s rate of water absorption. Porcelain brick water absorption e 0 5 ceramic brick water absorption e 10 the water absorption of the tiles refers to the percentage of the weight of the inhaled water after the mouth of the product is filled with water. A mere 0 5 in the case of porcelain tiles compared with 6 for stoneware ones groove by keraben. Weight of water absorbed as percentage of tile weight.

Laboratory reports individual test results for each tile as well as the average of 5 measurements. 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. Wet areas such as a shower or steam room should have porcelain tiles. Rustic tile glass mosaics resin mosaic.

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. It can directly describe the density of the product and affect the moisture resistance of the. Umbrella shielding rain nonvitreous. Absorbent value between 0 5 3 e g.

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. Ceramic tile that is fire glazed is 100 perfect for indoor floor use. Ceramic tiles have been produced from spent pot liner after oxidizing the same at high temperature to remove fluoride and cyanide content and burning out carbon value to obtain a vitrified mass which was later mixed with glassformer like soda lime silica glass collect fly ash from utility boilers incinerated ash lime stone gypsum silica sand and nucleating agents like.

Ceramic will absorb the moisture like a sponge but will only bead up on porcelain. Both ceramic tile and porcelain tile usually receive a surface glazing that makes them hard to distinguish from one another. Porcelain tiles have a far lower water absorption rate than glazed stoneware tiles for example. Not suitable for outdoor use or for rooms.
