  • As the use of cement increases with the development of modern society along with the increase of buildings, environmental pollution intensifies and researches on industrial byproducts are continuing. Research on blast furnace slag and fly ash as industrial byproducts is increasing, and research on industrial byproducts such as polysilicon sludge and paper ash used in this study is increasing. Blast furnace slag, which is one of the industrial byproducts, has been widely studied as a material used with cement. However, in this study, we fabricated lightweight matrix of polysilicon sludge and paper ash replaced based on blast furnace slag, and performed SEM analysis.

  • This study is the experiment for manufacturing the Lightweight non-cement matrix based on the blast furnace slag, paper ash. Materials like cement and blowing agent in foamed concrete is replaced by by-products fro blast furnace slag and paper ash. Further, the experiment was performed by replacing alkali with nature gypsum and α type gypsum by (0, 5, 10, 15, 20) of weight of alkali (wt.%) in order to reduce the amount of expensive alkali-activator. Consequently, in the case of the density, plain showed the lowest density and it seems that specimen adding nature gypsum 5% has the best compressive strength and flexural strength. It is detemined that the strength is lowered in accordance with the α type gypsum replacement ratio is higher. The research that it can supplement the further intensity seems to be needed.

  • In this study, the possibility of the use of a new raw material in paperboard industry was investigated. Fly ash is one of the residues generated in the combustion of coal and generally captured from the chimney of coal-fired power plant. This material is utilized in many industries including cement, soil stabilization, composite etc., but it is not used in paper industry. Three types of fly ashes were collected from Hadong, boryeong and Seocheon steam power plants and we investigated their properties by scanning electron micrographs and particle size distribution. Papers were manufactured with KOCC and fly ashes, and the physical properties such as bulk, tensile strength, internal bond strength and ISO brightness were measured to identify the effects of fly ash on the paper properties.

  • 본 연구는 제지 플라이애시 지반안정재를 활용하여 개량토 토사 비탈면의 현장 적용을 통한 안정화 방법을 연구하였다. 개량토에 요구되는 목표강도는 500kPa이며 토사 비탈면을 개량후 식생이 발아하기 위한 압축강도는 1,000kPa 이하이다. 이 조건을 만족하기 위해 현장에서 반입된 시료를 가지고 표층개량의 주원료인 지반안정재와 혼합하여 배합설계를 거처 강도시험 및 투수시험 그리고 식생 발아시험 등 다양한 시험을 실시 하였다. 그리고 개량토로 시공된 비탈면에 대한 기존 압축시험 결과를 분석한 후 개량토의 지반정수를 제안하였다. 또한 개량토의 비탈면 현장 적용성을 평가하기 위하여 붕괴된 비탈면에 대하여 현장 시공을 실시하여 개량토의 표층부 보강평가를 실시하였다. 그 결과 보강 전에는 안정성을 확보하지 못했지만 개량토로 보강한 이후 안전율은 강우 지속시간 48시간까지 최소 안전율을 확보하는 것으로 나타났다. 그리고 현장 개량토의 압축강도는 설계치인 점착력 200kPa 이상을 확보하고 토양경도계 시험 결과도 규정 값인 18~23mm 이내로 확인되어 개량토 비탈면의 경우 강우에 저항성이 증대되고 표층부의 식물생육이 가능한 것으로 나타났다.
