The study is to evaluate the physical properties of concrete under different curing conditions when some of the sands in the concrete are replaced by incinerator fly ash. The result indicated that when the incinerator fly ash was added to concrete, it would make concrete set earlier, increase early strength, and increase strength. The optimal amount of additive is between 15 % ~ 25 % of the weight of cement. The MTCLP was used in evaluation of leaching of heavy metals. According to 10 independently performed MTCLP, the total amounts of heavy metal bleached were below the regulatory thresholds measured by TCLP. As for the compressive strength of all the concretes exceeded the regulatory thresholds requirement. Accordingly, incinerator fly ash reused is feasible.
