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...

ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...

In the present study, a proprietary 0.2 tonne/h Dusty Cloud Separation (DCS) technology prototype by Value Ash Technologies NV (Belgium) was used to obtain ultra-fine fly ash as a novel by-product. Two types of Class F fly ash were used: separated fly ash (FA1) with particle size < 9.3 μm and ultra-fine fly ash (FA2) < 4.6 μm as sub-fraction of...
