Fly ash modified mortar with content of agloporite exposed to CO2 and high temperature

Popis výsledku v původním jazyce

This paper presents our research focused on the synergic influence of CO2 and extreme temperature on polymer-cement mortars. The basic criterion of the design for the composition of these materials was to achieve the required properties and maximum possible use of components originating from alternative raw material resources. For this reason, the matrix or binding component was modified with high temperature fly ash. Fly ash agloporite created a substantial proportion of the aggregate. Agloporite is a porous aggregate artificially produced by means of self-firing from high temperature fly ash. Mortars were subjected to tests of their resistance to carbonation in accordance with CSN EN 13295 and subsequently exposed to temperatures from 22°C to 1,000°C. Mortars were also analyzed in the longer term: after 90 and 150 days; physico-mechanical and physical-chemical properties, including microstructure, were analyzed (SEM, DTA, XRD and CT). It was determined that, as regards the analyzed influence of synergic action of CO2 and high temperature, the mortars showed considerable levels of resistance.
