Workability and Rheology of Flowable and Self-Consolidating Concrete

Self-consolidating concrete (SCC) is increasingly used by both the ready-mix and precast concrete industries. Its properties make it especially useful in specialist applications.

Covering both the fundamental and practical aspects of the rheology of cement-based materials, this book is a valuable guide for using SCC. It particularly emphasizes testing protocols and methods, directed for assessing the rheology and workability of highly flowable concrete and SCC. It also explains the effects of material characteristics, mixing conditions, and mix design parameters. Also covered are factors influencing the packing characteristics of aggregate, admixture demand, workability loss, robustness in production, surface quality, thixotropy and form pressure. Case studies highlight the techniques discussed, while relating the properties of fresh and hardened concrete to basic rheological parameters, such as the influence of combined yield stress and viscosity on the flow of SCC in a restricted area (filling capacity). It also dives you various approaches to concrete design and their significantly different rheological parameters and several merits are reviewed.

A key reference for professionals, which also offers graduate students a good grounding in the use of SCC.
