대한민국 대표 축제로 자리 잡은 보령머드축제의 핵심 프로그램인 머드 셀프마사지 행사의 재미와 다양성을 부여하기 위하여, 색상이 함유된 머드에 관한 연구를 수행하였다. 머드 고유의 낮은 명도를 조절하고자 이산화티탄을 첨가하여 머드의 질감을 유지하면서 색상이 발현되는 이산화티탄의 함량을 실험하고, 결정된 혼합비율에 황색산화철을 첨가하여 색상의 발현도를 색차계, 육안검사, 사용감 등으로 판단하였다. 결정된 색상은 물에 젖음 시 발색정도와 세척상태를 검토하여 보령머드 축제 프로그램인 머드 셀프마사지 행사에 사용하여 축제의 다양성을 높이고 또한 한국의 고유색인 오방색을 나타낼 수 있는 유색머드를 개발하고자 하였다.

During ballast of a LNG carrier, the mud at the sea floor can enter the tanks together with the ballast water if the LNG terminal is located at shallow water region. In order to remove the mud deposited on the tank floor during deballasting, the mud flushing system in the ballast tanks is applied. In this study, various analyses to conform the efficiency in the mud removal are performed. In order to design the mud flushing system, the particle size of the mud is measured by particle size analyzer. Flushing performance is evaluated by numerical analysis. From the results of numerical analysis including flow field and piping system network, the optimized flushing system is determined.

This paper aims to recycle red mud from a byproduct in the alumina industry as an alternative raw material for depleted natural resources. In order to apply red mud as a ceramic material, red mud ceramics were prepared according to mixing and temperature in a laboratory environment. Compared with KS L 4201 in terms of compression ratios and absorptions, it is found that two kinds of conditions for one type and three conditions for two types meet the standard. When red mud is used as a clay brick raw material, the substitution ratio of red mud is 10% or less, and the firing temperature is considered to be appropriate at $1200^{\circ}C$. In order to apply red mud to clay brick raw material in actual field, various samples and firing temperature should be considered in the future.

Red mud is an inorganic by-product produced from the mineral processing of alumina from Bauxite ores. the development of alkali-activated slag-red mud cement can be a representative study aimed at recycling the strong alkali of the red mud as a construction material. This study is to investigate the optimum water content, compressive strength, moisture absorption coefficient and efflorescence of alkali-activated slag-red mud soil pavement according to the recycling fine aggregate content. The results showed that the optimum water content, moisture absorption coefficient and efflorescence area of alkali-activated slag-red mud soil pavement increased but the compressive strength of that decreased as the recycled fine aggregate content increased.

This study was performed about color-contained mud to provide fun and diversity for the event of mud self massage as a core program of Boryeong Mud Festival which has become one of representative festivals in Korea. Adjusting its own lower brightness of mud and based on the primary study performed about the expressivity of yellowish colors, inorganic colors (oxidized steel in red, ultra marine pink, ultra marine blue, chrome oxide green) were added for the development of colored mud in diverse colors on the basis of Korean traditional colors. It had been judged about each expressivity of color by methods of colormeter, naked eyes inspection and feeling of usage, etc. For the color decided, it had been examined about the coloring when it got wet with the cleaning condition so that it can be used for the event of mud self massage as a program of Boryeong Mud Festival to increase diversity of the Festival and also attempted to develope colored mud to show Korean traditional colors.

Red mud is an inorganic by-product obtained from the mineral processing of alumina from Bauxite ores. A highly alkali inorganic waste product with a pH level over 11, red mud in its original state negatively impacts the ecosystem, so appropriate treatment is necessary. The development of alkali activated slag-red mud cement can be a representative study aimed at recycling the strong alkali of the red mud as a construction material. However, Alkali-activated binders that use sodium activators have been reported to be more vulnerable to efflorescence. Therefore, in this study, the compressive strength, pore characteristics, water absorption, elution characteristics, and efflorescence properties of alkali-activated slag cement mortar were assessed according to their red mud substitution ratio.

Red mud is an industrial by-product produced during the manufacturing aluminum hydroxide (Al(OH)3) and aluminum oxide(Al2O3) from Bauxite ores. In Korea, aproximately 2 tons of red mud in a sludge form with 50% moisture content is produced when 1ton of Al2O3 is produced through the Bayer process. Neutralization of red mud will help to reduce the environmental impact caused due to its storage and also lessen significantly the ongoing management of the deposits after closure. It will also open opportunities for re-use of the residue which to date have been prevented because of the high pH. Moreover, attention to liquefied red mud(LRM) that does not require heating and grinding process for recycling is needed. In this paper, characteristics of compressive strength for cement paste with content of LRM neutralized by nitric acid and sulfuric acid. The results showed that compressive strength of cement paste with neutralized LRM is higher than that of cement paste with LRM.

본 연구는 지방의 공동브랜드가 난립하고 있는 실정에서 보령머드의 차별성을 살리고, 원래 가지고 있던 고유성을 부각시켜서 시각적으로 이미지를 정립한 과정을 살펴보고자 한다. 공동브랜드의 가치를 높일 수 있도록 제품 이미지에 부합하고 소비자의 요구에 대응할 수 있는 디자인 방안이 제시되어야 한다. 그러나 현 시점에서 많은 공동브랜드가 유사성과 몰개성적인 난립으로 지역생산자에게 만족스러운 결과를 주지 못하는 부분이 크다. 보령머드는 이러한 점을 인식하고 보령머드의 현재 가치를 유지하면서 미래가치를 높일 수 있는 아이덴티티인 머드반지 개발과 적용을 브랜드 관리 차원에서 순차적으로 진행하고 있다. 세계인을 향한 보령머드의 약속을 상징하는 머드반지는 이미지 전달자인 보령과 이미지 수용자인 소비자 사이에 이러한 시각요소를 전달하고 있다.
