Foamed Eco-Geopolymer Modified by Perlite and Cellulose as a Construction Material for Energy-Efficient Buildings

Irreversible climate change, including atmosphere temperature extremes, is one of the most important issues present time. In this context, construction industry requires solutions for increasing energy efficiency buildings through feedback between adjustment inside and better isolation external parts buildings. Newly developed thermal insulation materials play an role in strategy. This paper presents foamed geopolymer based on metakaolin that can be used as a modern facade material. order to further improve its properties, composition was modified with organic substances, i.e., perlite cellulose fibers (30% 50% volume). The conductivity density, mineral phases, absorbability, compressive strength were improved composite materials. It has been shown final properties controlled great extent by modifications, determine applicability.
