Tiles testing method

 

                                                 Testing Of Tiles

Different types of test performed on tiles are as follows:

a)      Transverse strength test: It consists of applying the load along the center line a right angle to the length of the tile (which has been immersed in water for twenty-four hours) supported on the rounded edges of wood bearers. Six tiles are tested and the average breaking load should not be less than specified.

Flexural strength (N/mm2)   =15WS/bt2

 

Where W= breaking load, S= span in mm (3/4 of tile length), and b,           

 t= width and thickness, respectively.

b)      Water absorption test (IS:2690): Six tiles are dried in oven at 105+_5⁰C and cooled at the room temperature. They are then immersed in water for twenty-four hours. Thereafter these are wiped dry and weighted.

Absorption in %=w2-w1/w1x100

 

 

 

Where, w₁ and w₂are the respective weights of dry and the immersed specimens.

c)       Impact test (IS :1478)

d)      Breaking strength test (IS:1464): a sample of six tiles is used for the test
