Application of Superabsorbent polymers as novel admixture for cementitious materials
Superabsorbent polymers (SAP) are novel materials to be used as internal curing agent in concrete and mortars. Their high capacity to absorb and release water can help to control cement hydration processes and hence to avoid cracking susceptibility in cementitious materials. The effect is usually evidenced by the reduction of autogenous shrinkage which is associated with self-desiccation process. This paper aims to present an overview of SAP application in cementitious composites and to illustrate their efficiency by comparing experimental results of mortars with and without SAPs. The paper argues that not only autogenous shrinkage may be reduced but depending upon the type of SAP mechanical characteristics may also be improved.
