Geopolymers have appeared as promising materials in various fields as a result of the better properties relatively to ceramics and to cement-based materials.
However, further research is needed to understand the science behind the geopolymer technology.

So the traditional method to make the long development cycle, low accuracy and is easy to cause the waste of materials and other issues, this is bound to increase the cost of production[1] .
Injection Molding Process Based on Moldflow Moldflow is a software company's Moldflow series product, the company has been leading the market for CAE software, users can realize the choice of materials, through the Moldflow software product shape structure, mold design and molding process parameters were optimized.Especially for the flow simulation of thermoplastic plastics, more one's own knack in.
Fig 1 The mesh statistics and mesh model The choice of PP as the material analysis, the selection of PP series materials of Generic Default production, brand Generic PP, gate location analysis are shown in Figure 2.
Fig 2 The best gate area Moldflow based on the selection of materials will be recommended for initial injection conditions, melt temperature is 250℃, mold temperature is 60℃, injection time is 1s, pressure time is10 s and injection pressure of 80% others take automatic.

Parameter inversion and model optimization: physical properties of the geotechnical engineering materials and its mechanical characteristics is extremely complex, and indoor test again influenced by many complicated factors such as sample disturbance, the stress path, stress history and stress level and so on .
So the parameters attained by the back analysis can be regarded as the equivalent variables related to the model test materials.
Let for the equivalent elastic modulus of the equivalent wall materials and let for its inertial moment Let for elastic modulus of the core pile materials and let for its inertial moment.

Cementitious materials such as Portland cement are hydraulic binders which are commonly used in the conditioning of radioactive waste.
Before geopolymerization takes place, the fly ash feed materials need to be characterized to determine factors contributing to its synthesis behavior and overall end product quality.
Materials and Methods The fly ash used in this study was obtained from Sultan Salahuddin Abdul Aziz Power Plant, Kapar Selangor and Sultan Azlan Shah Power Plant, Manjung, Perak.
Microstructure of materials analyzed using field emission scanning electron microscopy (FESEM).
Study also showed presence of 226Ra, 232Th, and 40K radioactivity in the fly ash which makes the feed materials slightly radioactive although still below the regulatory limit to be classified as such.
