Environmental degradation of foamed geopolymers

Abstract Modern materials used in civil engineering should fulfill the numerous of requirements connected building standards, but not only. They also be ecological and durable. Geopolymers are characterized by very good mechanical properties, high resistance against acids, chlorides sulfates, thermal resistance, other properties confirmed previous research. There is still a few amount research with this for different environmental conditions, especially lack investigation foamed geopolymers area. The main objective article to analyze possibilities development new geopolymer composites increase durability, degradation corrosive water environments. This paper presents influence on environment. As raw materials, fly ash from coal power plant ‘Skawina’ (located in: Skawina, Lesser Poland, Poland) metakaolin (Czech Republic) were used. chemical composition typical class F. Additionally, reinforced flax fiber. Solid foam samples prepared. foaming agent, hydrogen peroxide (H $$_{2}$$ 2 O $$_{2})$$ ) was applied. following methods applied: compressive strength, flexural porosity measurements, absorption fresh salt water. results show that, however, conditions have significant composites; can successfully produced addition natural fibers strength parameters even after long-term use (materials tested 360 days).
