Understand how fresh concrete flows with a practical, physics-based approach. This book presents a simple plastic-viscosity model that links mixture composition to workability across six families of concrete and mortar. It explains a compressible packing view, introduces a compaction index, and shows how packing density affects viscosity and workability.
The discussion centers on how air, water, and particle packing influence the rheology of fresh mixtures. It covers how to estimate packing density for wet mixtures, how HRWRA dosages alter water demand, and how to translate these factors into a usable model for predicting plastic viscosity. The result is a coherent framework that integrates experimental data with a clear, physically justified method.
- How relative solid concentration and packing density relate to plastic viscosity for diverse mixtures
- How to compute virtual packing density and compaction index under different placement conditions
- Practical steps to apply the model to six families of fresh concrete and mortar
- Guidance on measuring binder effects and water demand in the presence of additives
Ideal for engineers and researchers working on concrete rheology, mix design, and quality control.
