Introduction Recently, several studies on Incremental Sheet Forming were presented in literature and most of them are focused on materials formability [1-4] and on the development of models able to predict material response, before any experimental test [5-6].
This results shows a high potential thinking to the possibility to investigate the application of SPIF to new materials or including new variables, such as the temperature during material processing at non-room temperature. 2.

However, with recent discoveries of extensive premature corrosion in new bridges, there are concerns regarding the long-term performance of such systems. [5] A completely different approach to control the corrosion process would be to use materials that are highly corrosion resistant, such as reinforcing bars constructed of composites materials.
The bond mechanisms of GFRP bars to concrete is significantly different from that of steel due to the differences in materials properties (both the fibers and resin) and geometry. [3] GFRP materials are anisotropic and are characterized by high tensile strength only in the direction of the reinforcing fibers.
Furthermore, GFRP materials do not yield; rather, they are elastic until failure.
For purposes of design, some researchers recommended that materials should have a Tg at least 30 °C above the maximum expected temperature. [18] Below zero temperatures can cause changes in mechanical properties and create additional micro cracks in GFRP materials.

The materials are classified as pozolanic material according to ASTM C618-2012.
The result is reasonable since density of lime is the lowest among other materials and the using of lime increased the water needs.
The properties of aerated concrete depend on its microstructure, composition of its materials, methods of pore-formation and curing [9].

However, it is significantly superior to these materials in inducing proliferation of the human osteoblast cell line.
Cell attachment and proliferation on these materials, titanium and polystyrene were investigated.
Dunnett's test [9] was used in both the attachment and proliferation assays to compare the control material (polystyrene) with the other tested materials.
As no phases were detected, none of the three materials had decomposed at 1200°C.
In contrast, there is no significant difference among the remaining materials for cell proliferation.
