Evaluation of various properties of ceramic floor glazed tiles

الملخص EN

This study aims at evaluating the various properties of ceramic floor tiles from the Egyptian local market.

Fifteen factories are registered at the Egyptian Industrial Union-Construction Material Chambers- Ceramic Department.

Test specimens were obtained from the local market for the fourteen factories during three months period (January till March 2008).

The specimens were all "of first choice" type.

The specimens were tested to determine water absorption, apparent porosity, apparent relative density and bulk density.

Evaluation of modulus of rupture, breaking strength, resistance to surface abrasion for glazed tiles as well as coefficient of friction were carried out according to both ESS (Egyptian standards Specifications) and ISO (International Organization for Standardization).

Test results indicated that most of the factories satisfy the requirements of both ESS and ISO for modulus of rupture and breaking strength.

The resistance to surface abrasion for specimens from the fourteen factories was classified as Class 3.

The dynamic coefficient of friction was in the range of 0.26μ to 0.66μ.
