Brief Description of Research Project

The research objectives of this Re-CAST study are to:

1. Improve methods for measuring and modeling formwork pressure of HPCAR,

and improve methods by appropriate laboratory experiments and

analysis.

2. Study fresh and hardened properties, and the transition from one to the

other. The transition from liquid to solid is not merely a function of

hydration, but of rheological behavior. HPC-AR must exhibit “robustness”

and “stability” in real-world application. Develop better understanding of

gelation and microstructure development to develop predictive models for

material properties.

3. Develop improved mixture design methodology to produce HPC-AR with

reliable, stable, robust performance while having desired flow and hardened

properties.

4. Conduct field tests of placement of HPC-AR in tall forms. Measure formwork

pressure, fresh properties, robustness, and assess all aspects of

constructability.
