Use of Ternary Mixtures in Concrete.

摘要

This manual is a summary of the findings of a comprehensive study. Its purpose is to provide engineers with the information they need to make educated deisions on the use of ternary mixtures for constructing concrete structures. It discusses the effects of ternary mixtures on fresh and hardened mixture properties and on concrete sustainability; factors that need to be considered for both structural and mixture design; quality control issues; and three example mixtures from constructed projects. A ternary mixture is one that contains portland cement and two other materials in the binder, blended either at the cement plant or at the batch plant. The materials included may be interground limestone or supplementary cementitious materials (SCMs) such as slag cement, fly ash, silica fume, or metakaolin.
