The porosity was enlarged compared with LP-free paste system. The results showed that neither monosulfoaluminate nor ettringite was found in any of the XRD patterns,instead carboaluminate was observed.Hemicarboaluminate produced in FA-PC or BFS-PC system transformed into monocarboaluminate with the addition of LP. The pore structure was evaluated by Mercury intrusion porosimetry(MIP). The mineralogy in pastes was identified by means of X-Ray diffraction (XRD) and thermogravimetry (TG). The mineralogy and pore structure were determined after 28 days of curing at 20☌ and 95% relative humidity. In order to better understand the synergistic effect, this article investigated the effect of LP on the microstructure ofPC-FA and PC-BFScementitious system. fly ash (FA) and blast furnace slag (BFS), has been documented.
