Valorisation of Industrial Waste for the Development of Fire Resistant Material to Be Used as Filler in Paints and Varnishes

The development of a Feslag based geopolymer [1] and its use is further examined.The developed geopolymer is used as a filler in paints, varnishes and plasters.The physical and thermal properties of those products are measured.It is shown that the materials present adequate mechanical strength, physical and thermal properties.All developed materials were subjected to thermal loading with the modification of a standardized passive fire protection test.The plaster succeeded to the test without failing in any of the criteria concerning the temperature in the unexposed surface of the specimen and its internal integrity.Further plaster testing on elasticity, open time, gloss value, alkali resistance and CO 2 carbonation protection is also performed on developed plasters with very positive results.
