Modelling compressive behaviour of cement paste with superabsorbent polymer

Superabsorbent polymer (SAP) can modify the microstructure and influence the mechanical properties of cement paste in at least two ways: while cavities left by SAP increase the total porosity, water released by SAP affects the hydration degree of the surrounding paste. As a starting point for investigation into the overall effect, this study...

Interactive mathematical model of self-healing in carbonated cementitious materials

A mathematical model for the post-damage recovery of carbonated cement is described. The model is based on a two-dimensional initial-boundary value problem for a system of partial differential equations. The study is embedded within the framework of investigating the effect of using lightweight expanded clay aggregate, which is incorporated into...

Role of modelling in the development of design methods for basal reinforced piled embankments

The paper details the role modelling (analytical, physical and numerical) has played in the development of design methods for basal reinforced piled embankments; specifically the level of embankment arching and the determination of the magnitude of the tensile loads in the basal reinforcement. The paper also reviews the major national design...
