Effects of Superabsorbent Polymers on Shrinkage of Concrete: Plastic, Autogenous, Drying

Chapter
Part of the RILEM State of the Art Reports book series (RILEM State Art Reports, volume 2)

Abstract

This chapter deals prospectively with one of the main applications of SAP in concrete construction, the mitigation of the autogenous shrinkage of concrete. In particular, the effects of using SAP as an additive for internal curing in cementitious materials with a low water-to-cement ratio and a low-permeability microstructure are presented and discussed. Since the addition of SAP, often in conjunction with extra water, influences not only autogenous shrinkage but also other types of volumetric changes, this is addressed as well in this chapter. Furthermore, the development of stresses due to restrained autogenous shrinkage is also considered for concretes with and without internal curing.
