In previous report streaming potential of aggregates and bond strength between aggregates and cement paste were investigated. Bond strength was affected by surface roughness andρpotential, i. e. bond strength increased with inρpotential and is stronger in the case of rough surface than smooth surface but this relation is not linear and the rate of increase becomes slower with the increase inρpotential. In this paper membrane potential of aggregates was investigated. It is belonged to the electrostatic phenomena in the electrochemistry. In previous report streaming potential is belong to the electrokinetic phenomena. Membrane potential of aggregates are affected by chemical constituentes that is less the content of SiO_2, greater the membrane potential and greater the contain of CaO+MgO, less the membrane potential. This is the same phenomenon as streaming potential. Membrane potential of artificial aggregate was affected by chemical constituent and burning temperature, that is less the content of clay, greater the potential and higher the burning temperature, less the potential.
