Time reverse modeling of acoustic emissions in structural concrete
Details on acoustic emission (AE). An often used application of AE analy- sis is the localization of concrete cracks and reinforcement ruptures. However, for progressed crack patterns, common localization procedures fail, because the waves have either been reflected repeatedly or experienced interference with other waves. In this dissertation a new method of AE analysis is developed which takes advantage of the wave field interferences.

On the mechanisms of shrinkage reducing admixtures in self con-solidating mortars and concretes
Compared to conventional concrete, SCC have an increased paste volume, and therefore show a higher shrinkage than conventional concrete. Shrinkage reducing admixtures (SRA) are proved to have the desired effect. Better understanding the working mechanism of SRAs was a main objective of this research. The effects on cement hydration, drying and shrinkage were investigated.

Certification of SRM 2492: Bingham Paste Mixture for Rheological Measurements
As measurements with rheometers can involve flow in a complex geometry, it is important that they are calibrated with a standard reference material (SRM). NIST has produced a Standard Reference material for paste (SRM 2492) as the first step for the development of a reference material for concrete rheometers. The process used to develop both the SRM 2492 and the mortar reference material is presented, including measurements, statistical analyses, and modeling. The developed SRM consists of a mixture of two components, corn syrup and fine limestone and has the texture of cement paste.

Kinetics of the Reaction of Calcium Hydroxide and Fly Ash
The reaction kinetics of a Type-F fly ash with calcium hydroxide (CH) has been investigated at temperatures between 25°C and 60°C. Thermogravimetric analysis (TGA) was used to determine CH consumption and production of hydrates (non-evaporable water) as a function of hydration temperature and time for various CH/fly ash ratios. The results indicate that the reaction rate, reaction stoichiometry and activation energy are dependent on the CH/ash ratio.
