Abstract

PURPOSE: To prevent lowering of water-resisting strength and also, to prevent the elution of noxious contaminated substance, by mixing dry process waste matter, such as incinerated ash etc., containing Cd, Pb etc., with water before kneading with asphalt and finishing the reaction of water reactive component and then, kneading with asphalt after drying.
CONSTITUTION: Dry process waste matter containing noxious contaminated substance of municipal garbage incinerated ash or electroprecipitator dust etc., such as Cd, Pb etc., is reacted with water reactive component (for example; Na2O, CaO, Al etc.) by mixing with water. Next, the above matter is dried after the reaction is finished and is kneaded with asphalt and then, is solidified in a fixed shape. By the above method, crushing strength of solidified formed body is heightened, because the substance lowering mechanical strength or gas is removed by carrying out pretreatment process reacting with water.
