Multi-scale Characterization of Oil-well Cements for Water Dynamics and Microstructure Analysis

The use of X-ray/Neutron Pair Distribution Function (PDF) technique proves to be useful in providing the critical insight into the retarder mechanism and as a basis to engineer the retarders for various oil-well cementing applications.
