Scanning Electron Microscopy Image Analysis (SEM-IA) was used to quantify the degree of alkali silica reaction in affected microbars, mortar and concrete prisms. It was found that the degree of reaction gave a unique correlation with the macroscopic expans ...
Cement pastes aged from 1 to 60 days were studied using synchrotron microtomography on the MS-X04SA beam line at the Swiss Light Source. This allowed three dimensional images to be obtained with a resolution approaching that of backscattered electron image ...
The role of cement in improving concrete durability is complex. Generally the role played by cement is secondary to the role of concrete mix design and curing. Some of these interacting effects are illustrated by discussing the roles of calcium hydroxide, ...
A RILEM technical committee on Internal Sulfate Attack (TC 186-ISA) was established in 1996. In the ensuing years considerable research was carried out, which helped to clarify the scientific knowledge surrounding this form of degradation. A Seminar was or ...
A fundamental research on cementitious materials at a Nanocem consortium comprising 21 academic and 11 industrial partners from 11 European countries is discussed. The research programme of the network consists of three core projects which includes hydrate ...
An Integrated Particle Kinetics Model (IPKM) to simulate the evolution of cement microstructure during hydration is presented. The advantages of the model are that the space is not divided into discrete pixels, so there is no lower resolution on the size o ...
