Abstract:We present a method of observing the relaxation process reflecting the motion of water molecules masked by the contribution of electrical conduction. By using this method, we can observe the Cole−Cole-type relaxation process reflecting the motion of the bound water molecules in cement-based materials. The relaxation time and strength of this process increase with curing time, and both parameters saturate to a constant value. The curing time dependence of compressive strength can be described by a logarithmic f… Show more
