    Nov 23 2016 · The cement pastes cured at 60 °C showed a similar electrical resistivity to the cement pastes cured at room temperature at early age but the electrical resistivity decreased at later ages. The observed electrical resistivity results can be interpreted in view of the effect of high temperature curing on microstructure.

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
