    • The present invention relates to environment-friendly bio drying cement mortar by using bituminous coal bottom ash which comprises: a bottom ash; an air-entraining agent; a water-reducing agent; and a bonding agent which comprises cement and a shrinkage reducing agent. Provided is the environment-friendly bio drying cement mortar using the bottom ash, wherein the weight ratio of a melamine based melamine water reducing agent about a naphthalene based naphthalene water reducing agent is 1.0 times or more and 5.0 times or less in the water reducing agent. The water-reducing agent is mixed as a ratio of 3.5% about the bonding agent, thereby having excellent water reducing effect and compressive strength; the shrinkage reducing agent is mixed as a ratio of 15% about the cement, thereby drastically reducing the drying shrinkage; and the air-entraining agent is mixed as a ratio of 0.06% about the total weight of the bonding agent by considering the porous properties of bottom ash, thereby preventing the reduction of compressive strength. The present invention has the excellent compressive strength and constructability by comprising the melamine based melamine water reducing agent and the naphthalene based naphthalene water reducing agent.

    • The present invention relates to a dry particle separation apparatus for using air-cooled coal-fired bottom ash for agricultural bed soil. The present invention provides a soft coal bottom ash processing apparatus for aggregate for agriculture comprising a first screening part for screening bottom ash being the residue of coal combustion; a first transfer device for transferring the bottom ash screened by the first screening part while cooling the bottom ash with air; a crusher for crushing the bottom ash transferred by the first transfer device; a second transfer device for transferring the crushed bottom ash while cooling the bottom ash with air; a first storage for storing the bottom ash transferred by the second transfer device; a second screening part for screening the bottom ash transferred to the first storage; a second storage including a dust-collecting filter at the upper part and storing the bottom ash screened by the second screening part; a particle separation part for receiving the bottom ash stored in the second storage and separating the particles of the bottom ash stored in the second storage; and an acidity treatment part for controlling the acidity of the bottom ash screened by the particle separation part within a range of 6 to 9. The present invention is environmentally friendly because there is no remaining waste such as sludge owing to water being used as a refrigerant. The bottom ash can be instantly used as aggregate for agriculture, civil engineering and construction because the bottom ash is completely sterilized by a reburning process. Energy efficiency can be maximized by heat recovery owing to the reburning process and the quantity of unburned carbon particles can be reduced, thereby reducing environmental pollution.
