Modified MSWI ash-mix slag for use in cement concrete
چکیده انگلیسی

In this study, fly- and scrubber-ash from a municipal solid waste incinerator (MSWI) were mixed uniformly in their production weight proportions; then, the mixture was added to waste glass frit and melted to form a glassy slag. The toxicity characteristic leaching procedure test results for the glassy slag revealed that the amount of leached heavy metals was far below the regulatory threshold. The slag-blended cement concrete (SBCC) specimens were manufactured with 20 wt.% of the cement replaced by slag powder. Three water/cementitious ratios, 0.48, 0.58 and 0.68, were selected to mold the specimens for compressive strength testing. The strengths of the SBCC specimens were close to or higher than those of the ordinary Portland cement concrete (OPCC) specimens at an age of 28 days and were 5–10% higher than those of the OPCC specimens at ages of 56 and 90 days. The experimental results demonstrated the feasibility of recycling MSWI fly- and scrubber-ash with waste glass.
