Abstract: This paper deals with the compressive strength development of cement pastes and mortars with superabsorbent polymers, SAP. Addition of SAP to high performance cementitious mixtures is done to reduce or avoid self-desiccation and self-desiccation shrinkage, but also influences the compressive strength. This study shows that whereas the compressive strength of high-strength cement pastes is slightly reduced by SAP addition, the strength of mortars is almost unaffected. Additionally, the paper examines briefly the effect on strength of degree of hydration and porosity, moisture conditions and pore structure of the SAP composites.
