✦ Synopsis

Synthetic clinkers, similar to high-silica Portland Cement clinkers, were prepared from raw material containing at times more than 50% oil shale from Har-Tuv area (central Israel) to which phosphate rock and laboratory grade CaC03 and Si02 were added. Although some clinkers contained more than 3% P205, their mineralogical composition was satisfactory (50 to 60% C3S). This result was obtained by taking into account in the SM formula the P20s concentrations. The resultant relatively high silica concentrations raise the melting point of the raw meal, causing a non-equilibrium state which allows the formation of C3S and its preservation.
