<p>PURPOSE:To provide the method for producing the material for civil engineering and construction from garbage which prevents the pollution arising from the generation of gaseous CO2 and the generation of dioxine by incineration of garbage and eliminates the need for the treatment of incineration ashes by reutilizing the garbage occupying the substantial part of municipal refuse without discarding. CONSTITUTION:The garbage fractionated and recovered at the time of recovering the municipal refuse is crushed and thereafter large iron pieces and aluminum pieces are removed therefrom. This garbage is charged into a disposer and is made into a slurry. The excessively high moisture of the slurried garbage is removed by drying to adjust the moisture content. Water contg. a cement admixture for curing cement to a ceramic state at ordinary temp. and cement are charged at prescribed distribution ratios into a kneading machine and are kneaded with the above-mentioned garbage. The kneaded raw material is pressurized and molded by using molds and is bonded and formed to a desired shape and size with high density by a water absorption reaction; thereafter, the molding is completely cured in a aging line.</p> |
