The results allowed us to affirm that the characteristics of this glass, in comparison with the tooth hard substances and other commonly employed inorganic dental materials, recommend it for further utilization in the dental field.
Ceramics are generally defined as inorganic, non-metallic materials.
Stress increased mutation phase contribution to the toughness .The composite material similar to natural tooth volume density, strength and hardness of natural teeth and excellent fracture toughness of dental materials to meet the performance requirements and the use for the special environment.

The use of fly ash in building materials is still limited, for example used as pile in road.
The oxides composition of precursor materials is shown in Table 1.
Red mud and EAFD slag contains finer particles than fly ash, making these materials are able to fill porous formed by fly ash.
Fly ash based geopolymer mortars is a potential material to be developed to replace cement based materials.

The addition of graphene as filler or as a platform improves the physico-chemical and electrical properties of conventional polymer materials.
In addition it enables to attain a low percolation threshold at lower loading fractions compared to other carbon materials[4].
Therefore it uses less amount of conducting filler and cheaper in contrast to other carbon particle materials.

One of the main reasons for the decline and exhaustion of wood materials in old buildings is biological factors.
According to the availability of local materials and hot climate in this region‚ most of architectural structures made with adobe.
