Durability of HPC

2.3.6.1 Introduction

Durability is one of the most important desired properties of concrete. Concrete is inherently a durable material. However, concrete is potentially vulnerable to attack in a variety of different exposures unless some cautions are taken. HPC that has a water/binder ratio between 0.30 and 0.40 is usually more durable than ordinary concrete not only because it is less porous, but also because its capillary and pore networks are somewhat disconnected due to the development of self-desiccation [75]. However, self-desiccation can be very harmful if it is not controlled during the early phase of the development of hydration reaction, therefore, HPC must be cured with more acres in order to achieve the designed properties. This section discusses the different durability aspects of HPC.
