Abstract
The paper presents performance analysis of fibre reinforced cement mortars modified by two types of superabsorbent polymers (SAP). Comprehensive studies of the mechanical properties, adhesion characteristics and shrinkage progress are accompanied by the microstructural analysis of composites. The effect of SAP water absorption capacities and the size of particles have a strong effect on the mechanical characteristics. Generally the higher absorption leads to the higher reduction in strength. The effect on flexural strength diminishes with the progress of hydration. The effectiveness of SAP for internal curing is evidenced in a reduction of autogenous shrinkage. Microstructural examinations (MIP and SEM) confirmed a negative effect of SAPs on bond between fibres and cement paste.
