Evaluation of hardened state properties of GGBS-PC mortars modified by superabsorbent polymers (SAP)
This paper evaluates the effects of superabsorbent polymers (SAP) on autogenous shrinkage, mechanical properties and microstructural characteristics of mortars with different levels of cement replacement by ground granulated blast-furnace slag (GGBS). Two types of SAPs with different water absorption capacities in cement-paste solution have been considered. The effects of SAP on mortars have been assessed during the first 28 days. The results showed that both polymers used notably reduce autogenous shrinkage. Moreover, the type of SAP has an effect on the pore structure formation in hardened mortars and consequently influences their mechanical properties.
