✦ Synopsis

The influence of Sea, ground, Nile and drinking waters on the microstructure of some hydraulic cements is investigated by means of X-ray diffraction analysis. The calcium sulfo-and carboaluminate hydrates form well with a water cement ratio of 2.

Seawater leads to the precipitation of gypsum.

The hydration products of ordinary portland cement (OPC) pastes hydrated for a year with the four water types are similar.

A survey on the analysis of waters used is given.
