Abstract

The hydrothermal hot-pressing method is found very useful technique for solidifying various inorganic powders. In this study, the hydrothermal hot-pressing method is applied to solidify pulverized concrete waste with the objective of developing a recycling technique for concrete waste. Although the tensile strength of the solidified concrete waste with no admixture was typically 5 MPa, the strength could be increased by addition of cement or slag up to 12-13 MPa. Furthermore, adding short fibers increased the fracture energy significantly, and the maximum fracture energy achieved in this study was approximately 8 kN/m.
