International Summit on Cement Hydration Kinetics

The Program Content

The following is a description of the workshop format and tentative (preliminary) program.  In keeping with the interactive nature of a workshop, the program has been designed to stimulate discussion while providing enough time for individuals to present their viewpoints and provide input.  The program is tentatively divided into six “Topical” Sessions, though some Topics may be subdivided into sub-Sessions where a large number of presentation proposals have been submitted.  The six tentative Topical Sessions are:

 

1.       Early Age Hydration (State I, II and III)

1.1   Early Stage Mechanisms

1.2   Modeling

1.3   Instrumentation and Experimentation

2.       Effect of Supplemental Cementitious Materials (SCMs)

3.       Post Peak Hydration (Stage IV)

4.       Thermochemistry and Geochmeical View of Cement Hydration

5.       Admixture Interactions

6.       Alternative Cement Systems

 

The Session Format

Each Session will be moderated by an appointed individual who is knowledgeable about the subject.  Each Session with have no more than five presentations by a select panel of experts.  Each presentation will be no more than 20 minute in length. The presentations will be followed by an extended moderated discussion period.  Detailed notes will be kept by a student scribe, to be used later as a form of transcript and for publication input.

 

The Topic format will incorporate as much time as possible for discussion and will focus on the discussion and will in general use the following format:

 

Opening Remarks – 15 minutes: The Moderator will be permitted to give opening remarks.

 

Presentations – 100 minutes: Each panelist will be given up to 20 minutes to present his or her viewpoint or recent developments in the field, this should address the Session’s list of questions that were distributed by the Moderator two months in advance.

 

Discussion – 100 minutes + as necessary: The Moderator will oversee a discussion period wherein the group at large can ask questions of the panel and the panel can interact to address and debate relevant topics.  During this period one of the student participants will record notes to be used by others for documentation.

 

The Moderator’s Job Description

The moderator of each session will be charged to develop a list of questions and distribute them to the panelists at least two months in advance of the meeting so that the panelists can be prepared to address those questions that they wish to.   These questions should be developed with input from the steering committee and other participants and might be done via this website’s blog feature.  The Moderator should come prepared to cultivate the discussion and keep the Session or sub-Session on track.
