Development of porous structure of ceramic-based geopolymers

Original language description

Geopolymers are alkali-activated materials produced by mixing silicate and aluminate phases containing minerals or aluminosilicates. This reaction results in stable polymeric networks of aluminosilicates. Nowadays, geopolymers have become very popular since they are seen as a potential alternative to ordinary concrete-based materials. They can be produced with the utilization of a variety of waste products. Therefore, the development of these materials can help to reduce greenhouse gas emissions from the production of concrete-based materials. This study aims to analyze the impact of different curing temperatures (25, 40, 60 and 80 °C) on the geopolymerization process, development of pore structure, basic physical and mechanical properties of ceramic-based geopolymers activated by alkali. Fine ceramic particles used for this study are an industrial waste from the final cutting of the bricks, and thus, this material is available in high quantities. The results showed that the thermal treatment of the fresh mixtures at selected temperatures accelerated the geopolymerization process which was clearly seen on the enhanced 28-days mechanical properties. Nevertheless, this enhancement was in contrary to the data obtained from mercury intrusion porosimetry, as the elevated temperatures of 80 °C led to an increase of porosity at samples
