Introduction Geopolymers represent a revolutionary class of materials with the potential to transform a wide array of industries, from construction to waste management.
These inorganic polymers are formed through the reaction of aluminosilicate materials with alkaline activators, resulting in a three-dimensional network of Si-O-Al bonds.
In contrast, geopolymers can reduce CO2 emissions by up to 97% due to their reliance on industrial waste materials and low-temperature processing [3-5].

The implant of cochlear electrode arrays is standard nowadays as a result of the improvement of medical surgery, equipment, and material properties.
Stöver and Lenarz discussed the fundamental material aspects of Cis as well as the potential for their future development [3].
The mechanical flexibility of the array must be flexible to fit into the cochlea in selecting its material.

Generally speaking, in accordance with the materials, building structure systems can be divided into the masonry structure with the bulk (standard clay brick) as the main material and the structural system with concrete or steel as the main material.
The commonly strengthening methods to the engineering structures are enlarging section method, paste composite material, prestressing method, sticking steel, outsourcing steel method and so on.

Experimental program Material used.
The typical morphology of hydration production of PSS paste with 6.4% w/w of gypsum was evident: a gel-like material surrounding steel slag grains.
The micrograph of sample with 6.4% gypsum at 14 days shows small amount of needle-shaped crystallized ettringite between gel-like materials (Fig.6 and the C–S–H gel formed a fibrous network structure in slag pastes.
