Effects of waste-glass fineness on sintering of reservoir-sediment aggregates

During sintering, waste-glass can reduce sintering temperature. Therefore, this study uses reservoir sediments blended with waste-glass with different degrees of fineness to investigate how waste-glass fineness affects the sintering behaviors and material characteristics of reservoir-sediment aggregates. Analytical results show that fine waste-glass powder smoothed the surface of reservoir-sediment aggregates and decreased the aggregate’s pore size. Moreover, the maximum failure point loading increased to 75.9%. When waste-glass fineness was >150 μm, this glass is suitable for sintering lightweight reservoir-sediment aggregates with a specific gravity of <1.8. Conversely, when waste-glass fineness was <150 μm, this glass was suitable for sintering reservoir-sediment aggregates with normal weights and a specific gravity exceeding 1.8. Waste-glass fineness affects the lightweight characteristics of reservoir-sediment aggregates more significantly than do volatile organic compounds. Adding finer waste-glass into reservoir sediment positively affects the chemical-corrosion resistance and potential alkali-silica reactivity of the reservoir-sediment aggregates.
