Abstract: 
Although the use of SAP as internal curing agents in concrete has been widely documented in the literature for over a decade their suitability for general use is still not clearly articulated and cohesive. The research programme, of which a fragment is presented in this paper, endeavours to elaborate on materials characteristics and performance of SAP modified mortars made of CEM I and CEM II type cements. The variations in microstructural features and mechanical/physical properties of composites are the subject of the presented investigations. Application of SAPs in CEM I resulted in reduction of shrinkage. The opposite effect in fly ash cement could be attributed to the altered water management. Differences in strength development in different composites can be attributed to the combined effect of SAP internal curing, fly ash pozzolanic reaction as well collapsing of SAP.
