Microstructure-based relative humidity in cementitious system due to self-desiccation

The internal relative humidity (RH) plays a crucial role in most of the concrete properties. Self-desiccation caused by continuous cement hydration is a major factor affecting the RH of concrete. This paper investigates the relationship between RH and microstructure for cementitious systems in the case of self-desiccation. A series of paste...

Experimental study on pore connectivity and its influence on chloride transport in saturated cementitious system

The purpose of this paper is to investigate the pore connectivity and its influence on chloride transport property in cementitious materials under saturated condition. Mercury intrusion porosimetry experiment was carried out on a variety of hydrated cement pastes curing up to one year. By repeating pressurization-depressurization cycles, pore...
