PURPOSE: The method is to provide prefabricated construction members of industrial waste materials which are recycled for use and are chemically and mechanically stable in water and in soil underwater to be free of pollution. CONSTITUTION: Waste material 50-100 wt.%, supplement material 0-50%, plastic component 0-15%, and hardener 0-5% are to be kneaded in admixture and molded under pressure into a form to be calcined at 700-1000°C.C.C and sintered at 1000-13000°C.C.C for 10-30 hours into blocks for use of constructing artificial reef for fish breeding. The waste material is one or more kinds selected from red mud from the refining process of aluminum hydroxide, slag from blast furnace, mine sludge, crushed glass pieces, stone powder from quarry, sewage sludge, incinerator ash, pulp sludge, coal mine side products. The blocks produced in the same process as in sintering of ceramics are stable chemically in seawater and have affinity for the water to be free of pollution for fish breeding.

PURPOSE: A method for manufacturing clay bricks is provided to optimize the reduction of the deformation of the bricks through a sintering process by adjusting the mixing ratio, the sintering time, and the sintering temperature of decarburization slag. CONSTITUTION: A method for manufacturing clay bricks includes the following: Water is added to an admixture of 30-60 weight% of decarburization slag and 70-40 weight% of clay. The particle size of the decarburization slag is 50mm or less. The water and the admixture are mixed. A vacuum pugging process is implemented to shape bricks, and the shaped bricks are dried and sintered at a temperature between 1050 and 1150 degrees Celsius for 1 to 24hours.

A method for manufacturing a loess structure using a modified tar sludge binder is provided to reduce a harmful influence on environment such as aggregate harvest, recycle waste resources, and restore an ecosystem. A method for manufacturing a loess structure using a modified tar sludge binder includes the steps of: removing oils from tar sludge generated from the coke industry; subjecting the oil-free sludge and a polymeric resin to thermal polymerization to produce a modified tar sludge; melting the modified tar sludge at 100-200 °C to produce a modified tar sludge binder having low viscosity; mixing 5-20wt% of the modified binder, 50-95wt % of loess, and 0-30wt% of other additive which is any one selected from incinerated residues, waste stone, recycled aggregate from waste concrete, dredged soil, slag, sand, waste foundry sand, and waste ceramic powder, or a mixture thereof; stirring the mixture in a hot mixer of 100 °C or higher; putting the mixture into a forming mold; vitro-pressing the mixture; cooling the mixture in water for a predetermined time; and performing demolding to produce the loess structure.

It is intended to provide a coloring agent for ceramic products whereby shot waste can be effectively reused and the production cost can be lowered, and a colored clay using the same. Namely, a coloring agent containing a metal powder obtained by fractionating shot waste in which a metal oxide powder contained in the metal powder serves as the fundamental material. A colored clay is obtained by adding this coloring agent to clay employed as the starting material.
