Application of superabsorbent polymers in blended cement mortars reinforced by polymeric fibre
Superabsorbent polymers (SAP) have been proved to be an effective internal curing agent which facilitate hydration process and control water supply of cement-based materials in the fresh, hardening, and hardened states. Although the use of SAP in concrete has been previously documented, however, its effect on prolonged hydration, microstructure alteration and mechanical characteristics of fibre reinforced mortars with supplementary cementitious materials (FRM-SCM) still remains unclear and deficient. This paper provides an overview of the effect of Superabsorbent polymers (SAPs) on short- and long-term performance of FRMSCM. The experimental results confirmed that the addition of SAP to FRM leads to notable reduction of workability and it has a dominant influence on mitigation of shrinkage of FRM-SCM. SAPs facilitate SCM hydration by a prolonged supply of water, adhered to smaller pores and by provision of space for deposition of secondary hydration products. Finer SAP is more effective and more efficiently facilitate improvement of compressive strength.
