Provided is a method for manufacturing panels used in building construction by utilizing waste glass fiber to thereby prevent environmental contamination caused by reclaiming or burning waste glass fiber. The manufacturing method of panels used in building construction comprises the steps of: cutting waste glass fiber with a cutter to a uniform size(10); preparing a polyester resin to be used as a binder(20) by mixing a thermosetting resin, an inorganic filling agent such as calcium carbonate, a hardener, and a releasing agent such as Zn-stearate or Ca-stearate; wetting the glass fiber and the polyester resin(30), which is accomplished by compressing the waste glass fiber and the polyester with a roll; and compression molding a glass fiber mat(40) by molding the compressed, half-hard sheet in a mold having a cavity therein.

A color concrete composite for fabricating structures is provided to be employed in manufacturing various coastal and/or offshore structures such as reef for fish or weed, bridge, TTP(tetra pod), port structure, etc. by comprising steel mill slag and/or furnace slag powder together with other materials including fly ash, lime stone and color pigment. The composite comprises: 65 to 84wt.% of at least one of steel mill slag or furnace slag; 10 to 24wt.% of furnace cement; 5 to 10wt.% of water; 0.5 to 1.5wt.% of an inorganic color pigment based on 100wt.% of the composite. The furnace cement is formed by mixing 25 to 64wt.% of Portland cement, 25 to 64wt.% of furnace slag fine powder, 10wt.% of fly ash and 1wt.% of calcined lime. The concrete structure is fabricated by the steps of: mixing all of the ingredients to prepare the composite; introducing the composite into a mold; compacting the composite in the mold by applying pressure or vibration to the mold; and curing the compacted mixture then releasing the cured product from the mold.

Disclosed are an ultra-light insulation material composition with superior flame-retardant and thermal resistance characteristic, an apparatus for manufacturing the composition, and a method for manufacturing the composition by using the apparatus. A flame-retardant layer including inorganic nonflammable material is formed on a surface of a chip, which is obtained by pulverizing expended polystyrene resin in a size below 3 mm. Through compress-kneading and pressing works with adding thickener, flame-retardant, curing control agent, auxiliary adhesive, dyes/pigments, and waterproofing stuff. The insulation material composition is subject to a pressing work including a vibration pressing work, a press pressing work, and an extrusion pressing work, so that the ultra-light composition can be rapidly obtained. Waste resource is reused and a tire and poisonous gas caused by the insulation material can be prevented. The composition makes a great contribution for solving a pollution problem and disposable polystyrene can be reused.

섬유로 보강되며 무기 충진재를 포함하는 전분 결합 매트릭스를 갖는 쉬이트 제조를 위한 조성물 및 방법이 발표된다. 쉬이트 형성에 적절한 혼합물은 물, 비변성 및 젤라틴화 안된 전분 과립, 셀룰로오스 에테르, 섬유, 무기 충진재를 필요한 성질을 가지는 쉬이트 형성에 적절한 비율로 혼합하여 제조된다. 이 혼합물은 한 세트 이상의 가열된 롤러 사이에 통과됨으로써 초기 쉬이트를 형성한다. 가열된 롤러는 셀룰로오스 에테르가 쉬이트 외면상에 스킨을 형성시키게 하여서 전분의 젤라턴화시 쉬이트를 롤러에 접착시키는 것을 방지한다. 초기 쉬이트는 가열된 롤러사이에 통과되어서 전분 과립이 젤라틴화하고 이후에 증발에 의해 물을 제거시킴으로써 쉬이트를 건조시킨다. 전분과 셀룰로오스 에테르는 섬유와 결합 매트릭스에 분산된 무기충진재와 함께 쉬이트의 결합 매트릭스를 형성한다. 전분 결합 쉬이트는 종이 또는 판지와 유사하게 절단, 감기, 압축, 스코링, 천공, 접힘, 접착되어서 쉬이트로 부터 제조품이 된다. 이러한 쉬이트는 식품 및 음료수 용기와 같은 용기의 대량생산에 특히 유용하다.
