Abstract: This research reports the effects of super absorbent polymers (SAPs) on linear early age shrinkage response of self-compacting cement paste systems (SCPs) containing fly ash (FA) and marble powder (MP) as secondary raw materials (SRMs) also called supplementary cementitious materials (SCMs). The results show that the use of powdered super plasticizer (SP) increased the early age shrinkage of self-consolidating paste systems (SCPs) without SRMs while the use of SAPs in SCPs induces some early expansion in all of the studied formulations. SAPs were also successful internal curing agents for the mitigation of early shrinkage of SCPs especially those containing fly-ash. In another side investigation by the authors, it was observed that SAPs work more efficiently in cement based systems without super plasticizer.
