Abstract:
Uniformly dispersed, hollow-core polymeric microspheres can protect concrete from freezing-and-thawing damage. However, issues with handling and delivery of this material have prevented its widespread use. The article presents test data that show the effectiveness of a new method of delivering such microspheres into concrete. The method is based on a microsphere-powder blend that minimizes particle agglomeration and eases handling and delivery of the microspheres into concrete mixtures.
