ASTM International Workshop on Cementitious Mixtures Scheduled for December

Words: Dan Kamys

A workshop on Methods for Investigation of Unexpected Performance and Properties of Cementitious Mixtures will be held Dec. 7, 2014, at the Sheraton New Orleans in New Orleans.

Sponsored by ASTM International Subcommittee C09.48 on Performance of Cementitious Materials and Admixture Combinations, part of Committee C09 on Concrete and Concrete Aggregates, the workshop will be held in conjunction with the committee’s standards development meetings.

As concrete and related mixtures become more complex, with multiple and/or unfamiliar cementitious materials and chemical admixtures, prediction of performance and properties becomes more challenging. Unexpected trends are experienced more frequently, and resolution is often elusive. The objectives of this workshop are:

  1. To present case history examples of unexpected performance and properties that have been observed in such mixtures and methods that were useful in evaluating and understanding them;

  2. To consider and generate dialogue on the extent to which various standard methods and standard practices such as those based on paste or mortar mixtures can be useful in understanding such behavior and leading to resolution of problematic trends, and

  3. To present new approaches and methods or modifications to existing tests or practices that have been productively used toward these ends.

The target audience will include but would not be limited to: concrete technologists responsible for the developing and/or specifying concrete mix designs; quality control managers of production concrete; and industrial and academic material scientists looking to further understand the complexity of cementitious-admixture-aggregate interactions.

Online registration is now open and closes Dec. 3. For registration and additional information, visit
