Presentations are Invited for ASTM International Workshop on Thermal Methods for Prediction of Properties of Cementitious Systems
Press release date: September 23, 2011
W. CONSHOHOCKEN, Pa.-Presentations are invited for a workshop on Thermal Methods for Prediction of Properties of Cementitious Systems, to be held on Dec. 2, 2012, at the Hyatt Regency Atlanta in Atlanta, Ga. Sponsored by ASTM International Committees C01 on Cement, C09 on Concrete and Concrete Aggregates, and the joint Subcommittee C01.48/C09.48 on Performance of Cementitious Materials and Admixture Combinations, the workshop will be held in conjunction with standards development meetings of the committees.
Thermal measurements are increasingly used as research and troubleshooting tools to capture the hydration kinetics of cementitious mixtures. As the cementitious binder reacts with water, it releases heat that can be measured either as heat flow (ASTM C1679, Standard Practice for Measuring Hydration Kinetics of Hydraulic Cementitious Mixtures Using Isothermal Calorimetry) or a temperature rise, resulting in a "fingerprint" of the reactivity of the mixture tested at the current conditions. Popular applications include but are not limited to:
Sulfate optimization of cement; Effect of temperature on hydration rate; Strength prediction using maturity (ASTM C1704, Standard Test Method for Sampling and Testing Structural Cementitious Panels); Incompatibility (C1679); Set time estimation; Finishing time and saw cutting time prediction; and Mix design optimization (selection of admixture and SCM).
Interested participants must submit a 250-300 word abstract via email to workshop co-chairmen Tim Cost (firstname.lastname@example.org) or Paul Sandberg (email@example.com) by June 4, 2012.
