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.

Paperback. Zustand: New. Print on Demand. This book delves into the fascinating world of fresh concrete rheology, a field that is often overlooked yet crucial to understanding the behavior of this essential building material. The author explores the complex relationship between the composition of concrete and its flow properties, a relationship that has long been understood in a qualitative sense but lacks a precise mathematical description. Drawing on extensive experimental research, the book presents a detailed analysis of the rheological characteristics of concrete, using various rheological models to explain the observed behaviors. Through this analysis, the author proposes a physical interpretation of the parameters involved in these models, revealing the key role played by factors such as particle size, surface roughness, and the presence of water-reducing admixtures. The book concludes with a practical application of these findings, describing a modified slump test designed to provide a simple and inexpensive method for evaluating the rheological properties of concrete in the field. This exploration of the complex rheology of fresh concrete offers valuable insights for engineers, materials scientists, and anyone seeking a deeper understanding of this fundamental building material.
