High strength concrete
Report on investigations into the effects of setting and hardening on the properties of high strength concretes, and in particular on the behaviour with restrained deformation at a young age. The shrinkage (in particular the autogenous shrinkage) as well as the release of heat of hydration and the associated strength development were investigated. [12 pages, 597 kB, PDF]

Mitigating Autogeneous Shrinkage by Internal Curing
Two different sources of internal water supply are compared: 1) replacement of a portion of the sand by saturated low-density fine aggregate and 2) the addition of superabsorbent polymer particles (SAP).

Registered on: Mar 15, 2005 | Category: Materials Science: Shrinkage-reducing Additives

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) .
