Some compositions in the lime rich portion of the CaO-SiO<sub>2</sub>-P<sub>2</sub>O<sub>5</sub> system are studied using laboratory reactants. The results showed that the compositions lying in the range of CaO = 69,5-70,1; P<sub>2</sub>O<sub>5</sub>= 16,2-19,5; SiO<sub>2</sub> = 11,1-13,6 (wt%) give, at 1000 °C, the mineralogical composition (HAp, β-C<sub>2</sub>S, C<sub>5</sub>PS) which can develop a high strength in chemically bonded ceramics. At high temperature (1400 ºC) these compositions give a large amount of silicocarnotite (C<sub>5</sub>PS) and 2C<sub>2</sub>.C<sub>3</sub>P phase. A selected composition of the industrial raw meal with added phosphate: CaO = 62,66; SiO<sub>2</sub> -= 17,33; Al<sub>2</sub>O<sub>3</sub> = 4,88; Fe<sub>2</sub>O<sub>3</sub> = 4,29; P<sub>2</sub>O</sub>5</sub> = 8,73; MgO = 2,09 (wt%) forms at 1350 ºC a clinker containing high amount of α-C<sub>2</sub>S to replace C<sub>3</sub>S. Such a clinker may have good applications in the synthesis of active belite cement.}, number={237}, journal={Materiales de Construcción}, author={Diouri, A. and Boukhari, A. and Aride, J. and Puertas, F. and Vázquez, T.}, year={1995}, month={Mar.}, pages={3–13} }
