Admixture Compatibility of Alternative Supplementary Cementitious Materials for Pavement and Structural Concrete

摘要

The objective of this research project were (1) to gain a better understanding about the interaction among alternative SCMS and chemical admixtures in Portland cement mixtures (2) to facilitate implementation of alternative SCMs in transportation structures. Such information can assist in the encouraging adoption of alternative SCMs in the United States, both in pavement and structural applications. In order to accomplish these goals, the NUTC project: (1) Investigated the influence of selected types of alternative SCMs on air-void system in concrete for pavements (2) Investigated the influence of selected alternative SCMs on key fresh and hardened properties of concrete designated for structural applications.
