Shrinkage Reducing Admixtures – Their Science and Role in Education
Speaker: Professor Jason Weiss, Edwards Distinguished Chair of Engineering, Oregon State University

Title: Shrinkage Reducing Admixtures – Their Science and Role in Education

Shrinkage-reducing admixtures (SRAs) emerged on the scene in the 1980’s. While these materials have been introduced to reduce the risk of restrained shrinkage cracking in concrete; they have several additional benefits. This presentation will review properties of shrinkage reducing admixtures in an effort to describe how they reduce shrinkage. Discussions will include surface tension, viscosity and contact angle. The presentation will highlight their influence on shrinkage, shrinkage cracking, moisture diffusion, plastic shrinkage, and transport properties.
