Characterization of ASR products formed in concrete aggregates

ASR products formed in various aggregates of two different concrete mixtures tested both at 38 °C and 60 °C with the concrete prism test have been analysed by scanning electron microscope with energy dispersive X-ray spectroscopy. Additionally, Raman spectra of ASR products have been acquired. The variations in the chemical composition of ASR...

Autogenous shrinkage of HPC and ways to mitigate it

The Integration of EIS parameters and bulk matrix characterization in studying reinforced cement-based materials

Corrosion in reinforced concrete is a major and costly concern, arising from the higher complexity of involved phenomena on different levels of material science (e.g. electrochemistry, concrete material science) and material properties (macro/micro/ nano). Reinforced cement-based systems (e.g. reinforced mortar and concrete) are multi-phase...

The characterisation, improvement and modelling aspects of Frost Salt Scaling of Cement-Based Materials with a High Slag Content

Blast furnace slag cement concrete is used extensively in a number of countries. In comparison with OPC, it is particularly well known for its excellent performance in marine environments. One dis-advantage of slag cement is its vulnerability to scaling under the combined load of freezing-thawing and de-icing salts. The current investigation was...

Microstructure and properties of styrene acrylate polymer cement concrete

The paper systematically describes the evolution of the microstructure of a styrene acrylate polymer cement concrete in relation to its mechanical properties and durability. The results presented and discussed at the present paper involve the interaction of the polymer dispersion with portland cement; the effect of the polymer modification on...
