In 2011 I've received a Marie Curie grant and became a part of TRANSCEND project. I'm enrolled at the 4 years Engineering Doctorate (EngD) course at University of Surrey. But I carry out my research activity at Lafarge Research Centre in France.
The main goal of the EngD is to couple a 2D 1H NMR (proton Nuclear Magnetic Resonance) technique with temperature variation. This allows effectively freeze out larger pores and explore connectivity between the smaller pore. Thus we aim to better understand the microstructure of C-S-H (calcium silicate hydrate) - the main binding phase of the cement.
During nearly 4 years of the project, a number of reference SiO2 materials with known porosities were studied with coupled cryoporometry - relaxometry technique. The studies reviled a hidden pore wall - water interaction, which is very similar to the processes occurring in cements especially on a nano-scale.
2D T2-T2 (REXY) was applied to the synthesised C3S phase. The existence of complex connectivity and different rates of the water transport within the nano porosity of C3S was shown.
I expect to defend in the beginning of 2016.
