This book aids concrete producers in improving the quality of ready mixed concrete. It quantifies the benefits of improved quality in terms of cost savings, increased efficiency and consistency, and sustainability. It shows the relation between concrete quality and concrete strength variability, and discusses the components of variability and how one could methodically relate component changes to variability in concrete strength and other properties. It also recommends specific steps that producers might take to reduce component variability and achieve a more consistent product.
