Abstract

PURPOSE:To effectively utilize a refuse fuel incineration ash which is a waste and obtain a high-strength air milk suitable as a mounding material, etc., without causing temperature cracking by mixing the refuse incineration ash with cement, water and a foaming agent. CONSTITUTION:A refuse fuel incineration ash is mixed with a cement (e.g. a high-early-strength cement), water and a foaming agent (e.g. an alkylarylsulfonate) to produce an air milk. Bubbles at 0.1-0.2 volume ratio are more preferably mixed in a mixture prepared by mixing 1 refuse incineration ash with the cement at 0.1-0.25 weight ratio, water at 1-1.25 weight ratio and a high-performance water-reducing agent (e.g. naphthalene-based water-reducing agent) at 0.011-0.02 weight ratio to produce the air milk. Thereby, since the surface area of the refuse incineration ash is large, the material separation such as bleeding is eliminated and a small amount of the cement is sufficiently used simply by mixing the refuse fuel incineration ash therein.

Since water and a foaming agent are mixed to produce air milk, cement hardens the air milk and develops strength. On the other hand, bubbles are generated by the foaming agent, and the weight of the air milk is reduced. At this time, the specific gravity of the air milk can be freely set by changing the amount of bubbles.

In addition, the amount of cement used can be reduced by mixing incinerated ash from waste fuel. According to the invention of claim 2, by using the high-performance water reducing agent, the fluidity of the air milk is improved, and the strength of the air milk is also improved by reducing the unit amount of water.
