Original Abstract

Alkali activated aluminosilicates present a promising way for future advances in materials engineering towards environmental sustainability. In this paper, the mechanical, thermal and hygric properties of aluminosilicates designed using waste brick powder from insulation blocks are investigated. The applied waste material is alkali activated by the mixtures of sodium hydroxide and sodium silicate with the silicate modulus ranging from 0.8 to 1.4. The obtained results reveal a significant influence of increased silicate modulus on the properties of analyzed aluminosilicates. The more dense and compact material structure observed for higher silicate moduli leads to an improvement of mechanical properties of designed materials. The thermal and hygric properties are found to be influenced by the occurrence of cracks in the material structure. The experimental results indicate a good potential of alkali activated aluminosilicates for design of new building materials in tenns of sustainable development principles.
