Abstract Aiming at the problem of a large amount of municipal solid waste (MSW) incineration slag and difficult utilization, the research topic of using MSW incineration slag instead of natural sand as the fine aggregate of concrete is proposed. Three water-binder ratios ( 0.2, 0.4 and 0.6) and three sand replacement ratios ( 0%, 25% and 50% ) were selected. The change laws of macro-mechanical properties and micro-structure of MSW incineration slag fine aggregate concrete and ordinary concrete under different freeze-thaw cycles and self-healing after freeze-thaw were studied. The results show that the compressive strength decreases gradually with the increase of freeze-thaw cycles, but the strength reduction of MSW incineration slag fine aggregate concrete is less than that of ordinary concrete, indicating that the freeze-thaw resistance is better than that of ordinary concrete. After self-healing curing, the strength of MSW incineration slag concrete and ordinary concrete has a certain increase, because of the potential hydraulic hardness of MSW incineration slag, the growth rate of self-healing strength is greater than that of ordinary concrete.

Key words： municipal solid waste incineration slag concrete fine aggregate freeze-thaw cycles self-healing
