4. Description Abstract

In this work, we studied the comparative between the effect of inorganic additions such as the P.Lime and the PN on the physical-chemical properties of cement and the mechanical performances of mortar and/or concrete, while partially substituting the clinker by these materials, at various percentages ranging from 5% to 40% of each add by weight of cement with an interval of 5%.

The obtained results by the different formulations elaborated show that the substitution a part of clinker by PN and/or P.Lime produced a new durable hydraulic binder with the physical-chemical and mechanical properties improved, namely the increases in the fineness by specific surface, the density is decreased, the setting time decreased as a function of the increase in the percentage of P.Lime and increased with the increases in the percentage of PN, the report of water/cement decreased as a function of the mass fraction of PN and increased with the percentage of P.Lime. The compressive strength at a young age (2days), median age (7days) and long term (28days) improve with the percentage of P.Lime and/or PN was increased.
