Microstructure and properties of Pb(Mg1/3Nb2/3)O3-Portland cement composites

Lead magnesium niobate, Pb(Mg1/3Nb2/3)O3(PMN), ceramics particles was mixed with Portland Cement (PC) using a water to cement ratio of 0.50 and PMN content at 40% and 60% by weight to produce 0-3 Pb(Mg1/3Nb2/3)O3-Portland cement (PMN-PC) composites. Microstructure and hydration of the composites wer...
