Electrical measurements are one of the oldest techniques also used in materials science.
The positron annihilation technique is one of the nuclear methods used in material science.
The advantages of this method are in the obtaining of both qualitative and quantitative data on defect behavior in materials.
The main assumption of the simple trapping model is that positrons annihilate in solid materials from a free or trapped state.
This model assumes that the positron exists in one of only two states in the materials, the free or Bloch state and the defect trapped state.

Material Characterization Applied materials.
Generally, no higher than ±1.0° average deviation occurred for all materials during the experiments.

Introduction Geopolymer is an aluminosilicate materials process by dissolving it in highly alkaline solution, then transform into three-dimensional tecto-aluminosilicate materials.
According to the material demanding in coating industry, geopolymer is inorganic materials, and unlike most of organic materials in coating industry which harmful to both humans and the environment.
Experimental Setup Raw materials.
