When the nano MgO content was 1.0%, the fluidity of the oil-well cement slurry worsened because the water demand of nano MgO increased and generated Mg(OH) 2, which also caused the consistency of the cement paste to become worse. The nano MgO has a small bulk density, which may affect the bulk density of the freshly mixed specimens.
