Increasing accumulation of inorganic waste has been becoming one of the most serious problems from the point of environmental loading. As the useful mean to solve the problem the development of the recycle technique has been required. Especially the production of the new material by mixing together more than two kinds of raw materials is more useful method. However, a number of trials are required in this method. It is available to make clear the target of production first. In this study, the targets of the production are the glass ceramics with the prismatic crystals of an Anorthite,Wollastonite, and Gehelenite, and inorganic wastes as fly ash, concrete sludge, and glass cullet are selected as construction materials. Some batches were prepared by mixing these inorganic wastes in the weight ratios determined on the basis of a phase equilibrium diagram of CaO-Al2O3-SiO2 to get the desired materials. Glass samples were produced by melting the batches at 1400°C. From these batch compositions, the amorphous glasses were produced. They were reheated in the region of crystallization temperatures to make them transform into glass ceramic. The properties of the obtained glass ceramics were examined by XRD analysis, SEM observations, and strength tests by four point bending. The XRD analysis and SEM observations showed that the crystallized phase of the produced glass ceramic samples were identified as Anorthite, .Wollastonite, and Gehelenite, respectively. The strength test showed that any glass ceramics have the high strength of 80 to 90 MPa, and can be applied for various facets of the construction materials.
