Preparation and properties of alkali activated fly ash foam

Popis výsledku v původním jazyce

This work aims at description of inorganic foams based on alkali activated fly ash. The foam is produced from alkali activated fly ash paste by powder alumina which reacts with the alkalies from the activation solution. Hydrogen is released during this reaction and creates a closed-pore structure. The amount of liquid activation solution and powder alumina has been optimized considering proper pore distribution and prescribed bulk density of the foam. The viscosity of the initial mix was found as a crucial factor for the foaming process and for the stability of the fresh foam. Compressive strength, flexural strength, thermal conductivity and capacity and residual strength on matured specimens were measured and compared with traditional porous buildingmaterials. The fire-resistance of the fly ash foam was determined. Mass loss, volume change, compressive strength and elasticity was obtained. It was found that during the fire resistance test almost all mass loss occurres below 500°C. On
