Aluminosilicate binders are generally electrical insulators; however, electrical properties of building materials gain the importance in the new field of applications such as self-sensing or self-heating materials.
Materials and Methodology Materials.
The main difference in capacitance between both materials was observed at low frequencies.
Although aluminosilicate materials are considered good electrical insulators and the resistivity of cement-based materials is very high, substantially different electrical behaviour was observed for alkali-activated slag.

To evaluate the freeze-thaw resistance of the specimen, a 100×100×400mm prismatic specimen was manufactured, and it was cured in water for the material age of 28 days.
For mixing the high-performance concrete, a fan-type mixer with the capacity of 80 liters was used, and the constituent materials were separately and uniformly injected in the (cement+fine aggregate)→(water+AE agent)→(coarse aggregate+viscosity agent) stages, as summarizes in Table 4.

Introduction Modern building solutions demand permanent and good quality building materials such as bricks with excellent heat insulation and freeze-proof roof-tiles [1,2,3].
The quality of the raw materials used play a key role in the success of the final product besides the developing of production processes [4,5].
