Clinker minerals, dry Portland cement and hydrating Portland cement paste were studied by small-angle neutron scattering. For a clear characterization of the scattering results the clinker minerals and the Portland cement powder were separated into several fractions of grain sizes. Observing the sh

✦ Synopsis
The stage of hydration of hardened cement paste (hcp) has been investigated by small-angle neutron scattering (SANS) from the beginning of the hydration process up to 28 days. A special mixture of HnO and D.O eliminating the various influences of the ~linker ~hases was used as mixing water. SANS-experiments have shown the correspondence of the deveIopment of the radii of gyration with the increasing volume of the hydration products. Therefore the radius of gyration is a useful scattering parameter for the characterization of the hydration progress.

Finely divided fumed silica (Aerosil) has been used as a model substance to interpret the change in fractal dimension and specific surface of hardened cement paste (hcp) with relative humidity. Hcp is essentially a surface fractal at relative humidities below ca. 40% where the specific surface dimin

## Abstract Amorphous blends from a deuterated polyaryletherketone and a polyetherimide have been prepared and investigated by neutron scattering. The used components differ remarkably in their structure and their solution properties. The blends on the other hand are combinatorial mixtures: the sca
