     View Summary

    Rigid plastic and large deformation analyses of the finite element method (FEM) require multiple remeshing procedures to avoid a decrease in the analysis accuracy. Thus, a three-node triangular element that can perform automatic mesh generation is suitable for these FEM analyses. However, in the FEM analysis of nearly incompressible materials using the displacement-based three-node triangular element, the inhibition of volumetric locking and pressure checkerboarding is required. The generalized finite element method (GFEM) approximation can improve the analysis accuracy for three-node triangular elements without the addition of midpoint nodes. In this study, we performed a detailed performance evaluation of a three-node triangular element based on the GFEM approximation for nearly incompressible materials in the linear elastic analysis. The GFEM approximation employs a polynomial of degree 1–3. Performance investigation using a compression test revealed that each GFEM element required the application of selective reduced integration to avoid volumetric locking and pressure checkerboarding. Furthermore, we investigated the number of constraint degrees of freedom of the GFEM element, which is related to volumetric locking. In the case of the GFEM element, we inferred that the application of this investigation is difficult because of the additional nodal degrees of freedom, which are different from the translational nodal displacement.

     View Summary

    <p>This study investigated the conditions for zeolite synthesis from waste concrete powder (WCP) using the hydrothermal synthesis method. The WCP was prepared by milling the waste concrete using pot mill equipment. The synthesis conditions, i.e., the heating time, heating temperature, and NaOH solution concentration were varied. Furthermore, hydrochloric acid-treated WCP (WCP-HCl), which is removed the calcium component, was prepared to examine the effectiveness of acid treatment in the zeolite synthesis. The zeolite synthesis was investigated using X ray diffraction (XRD) and scanning electron microscopy (SEM). Analcime-type zeolite was synthesized using WCP and WCP-HCl. The requirements of synthesis conditions for analcime were as follows: heating time above 12 h, heating temperature above 433 K, and NaOH solution concentration above 2 mol/L. With a progressive increase in the concentration of the NaOH solution from 5 to 7 mol/L, analcime could be synthesized at NaOH concentrations below 4 mol/L, while cancrinite was synthesized at NaOH concentrations exceeding 5 mol/L. The peak intensity of analcime and cancrinite of WCP-HCl showed high value in comparison to the WCP. Thus, the effectiveness of the HCl treatment of WCP was confirmed from the XRD patterns.</p>
