Mitigation Strategies for Autogenous Shrinkage Cracking
The fundamental parameters contributing to the autogenous shrinkage and resultant early-age cracking of concrete are presented. Mitigation strategies which are discussed include: the addition of shrinkage-reducing admixtures more commonly used to control drying shrinkage, control of the cement particle size distribution, modification of the mineralogical composition of the cement, the addition of saturated lightweight fine aggregates, the use of controlled permeability formwork, and the addition of superabsorbent polymers ("water-entrained" concrete) .

Influence of Mineral Admixtures on the Rheology of Cement Paste and Concrete
Rheological tests on cement paste were used to successfully select the type and dosage of mineral admixtures that improved concrete workability. Among the six different mineral admixtures tested, the ultra fine fly ash was determined to give the best results by reducing the yield stress and viscosity.
