Influence of Chemical Additives and Curing Conditions on Mechanical Properties and Carbonation Resistance of Alkali Activated Slag Composites
Original language description
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). Materials for the sample preparation were blast furnace slag activated using sodium silicate and AEA or SRA varying in content. Curing of samples was carried out in various conditions (air curing at laboratory conditions and water curing at the same temperature) and influence of these was studied too. The prepared samples (specimens with dimensions of 100 mm x 20 mm x 20 mm) where tested on compressive and bending strengths. The experimental results have shown that the addition of AEA had not significant influence on the mechanicalproperties while the addition of SRA had negative effect. However, the carbonation resistance markedly decreases with increasing amount of both agents. The same stands for the air curing as mechanical strengths are lower compared to those
