ASTM workshop on cementitious mixtures

On 7 December, ASTM International is holding a workshop in New Orleans on Methods for Investigation of Unexpected Performance and Properties of Cementitious Mixtures. The workshop will be sponsored by ASTM International Subcommittee C09.48 on Performance of Cementitious Materials and Admixture Combinations, part of Committee C09 on Concrete and Concrete Aggregates. It will be held in conjunction with the committee’s standards development meetings.

The objectives of this workshop are:

• 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.
• 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 behaviour and leading to resolution of problematic trends.
• 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 3 December. For registration and additional information, visit www.astm.org/C09Wrkshp12-14. Additional technical information is available from workshop co-chairmen Tim Cost, Holcim US Inc., Canton, Miss. (phone: 601-856-2487; tim.cost@holcim.com) and Ara A.
