Aggregate proportioning for slip formed pavements and flowable concrete
Abstract
This is an investigation into developing a relationship between aggregate proportioning and the workability of concrete for slip formed pavements and flowable concrete applications. Workability tests were developed for each application. Various aggregate proportioning techniques and aggregate concepts were evaluated. The aggregate proportioning technique based off gradation was shown to predictably change the workability of the concrete. Almost 800 different mixtures were conducted to validate workability tests and also develop gradation and proportioning limits for slip formed pavement and flowable concrete applications. These gradation and proportioning limits were further investigated to find insights into a mechanism.
