As is known, smelting dust has been reclaimed so far. But, it has the possibility of being used as a recycled material. When it is used as a substitute for cement, the amount of cement can be decreased. However, there is a problem with this; the amount of the hydroxide calcium in the concrete will also be reduced, thereby affecting the strength and the durability of concrete due to neutralization and other influencing factors. This research has clarified the reactivity of smelting dust and hydroxide calcium. First, the change over time of the amount of the hydroxide calcium in the paste was measured. Then, some basic experiments were conducted concerning fresh properties and the coagulation stiffening reaction of the concrete when some percentage of the cement is substituted for smelting dust. We have tried to detect how much the substitution addition rate affects various physical properties of the concrete.
