Abstract

The behaviour of cemented granular material is complicated by the fact that the eventual cemented properties depend on the conditions under which cement hydration (curing) takes place. There are a number of situations in industry where granular materials are mixed with small quantities of cement and deployed in highly transient curing environments. Understanding and predicting the responses in these situations requires a constitutive model where cemented properties are an output, rather than a pre-determined input. This paper presents a constitutive model that is capable of representing the formation and destruction of bonding in weakly cemented granular material in a transient stress environment.
