Influence of Chemical Additives and Curing Conditions on Mechanical Properties and Carbonation Resistance of Alkali Activated Slag Composites

Popis výsledku v původním jazyce

The main aim of the presented work is to investigate the effect of the addition of air entraining (AEA) and shrinkage reducing agents (SRA) on mechanical properties and carbonation resistance of alkali activated slag (AAS). The materials used for sample preparation were blast furnace slag activated using sodium silicate and AEA or SRA in varying amounts. Samples were cured in various conditions (air curing at laboratory conditions and water curing at the same temperature) and the influence of these was also studied. The prepared samples (specimens with dimensions of 100 mm × 20 mm × 20 mm) were tested for compressive and bending strengths. The experimental results show that the addition of AEA did not have a significant influence on mechanical properties, while the addition of SRA had a negative effect. However, carbonation resistance markedly decreases with an increase of both agents. The same is true for air curing, as mechanical strengths are lower compared to those samples cured in water and the ratio of the strength of the air-cured composite and that of the water-cured composite decreases with an increase in the content of SRA.
