TL;DR: In this article, a method for reducing autogenous shrinkage in a material based on a hydraulic mineral binder, e.g. cement, by preparing a mixture comprising the binder and water and a water-entraining agent selected from the group consisting of hydrogels and microencapsulated water, casting the mixture in a desired configuration, and allowing the mixture to cure.

TL;DR: In this paper, various mechanisms suggested to cause autogenous shrinkage are presented The mechanisms are evaluated from the point of view of their soundness and applicability to quantitative modeling of autogeneous shrinkage.

TL;DR: In this paper, a new concept for the prevention of self-desiccation in hardening cement-based materials is proposed based on using fine, superabsorbent polymer (hydrogel, SAP) particles as a concrete admixture.

TL;DR: In this article, the effects of the size distribution of Portland cement particles on a variety of performance properties are explored via computer simulation and a few experimental studies, including setting time, heat release, capillary porosity percolation, diffusivity, chemical shrinkage, autogenous shrinkage and internal relative humidity evolution.

TL;DR: An overview of autogenous deformation and change of the relative humidity (RH-change) can be found in this article, where an overview of the current status of this research field is given.
