염화물함유 콘크리트의 투수성과 철근부식에 미치는 영향을 규명하기 위해 염화물 함유량을 0, 0.3, 0.6㎏/㎥으로 변화시키고 W/C비를 0.4, 0.45, 0.5, 0.6으로 변화시킨 상태에서 투수계수, 철근 부식면적율, 압축강도, 슬럼프, S.E.M에 의한 미세구조를 보통 콘크리트, fly ash 혼입 콘크리트, AE 혼입 콘크리트와 비교하여 다음과 같은 결론을 얻었다. 1) 콘크리트 투수계수는 W/C비 또는 염화물 함유량이 클수록 증가하였다. W/C비 0.5까지는 투수계수의 증가폭이 크지 않으나 W/C비 0.65에서는 염화물 혼입 및 보통 콘크리트의 투수계수가 크게 증가하여 W/C비가 염화물 함유량 보다는 특수성에 더 큰 영향인자임을 알 수 있었다. 2) 철근부식 면적율은 투수계수와 마찬가지로 W/C비 또는 염화물 함유량이 클수록 증가하였다. W/C비 0.65에서 보통 콘크리트의 투수계수는 염화물 혼입시와 유사하나 철근부식 면적율은 현격히 작은 결과를 나타내 투수계수의 증가에 따라 철근부식 면적율이 반드시 비례하여 커지는 것은 아님을 알 수 있었다. 3) 플라이애쉬 및 AE감수제를 혼입하면 콘크리트 투수계수 및 철근부식 면적율이 크게 감소하여 밀실화 효과가 우수하였으며, 피복두께를 2㎝에서 3㎝로 증가 시키면 염화물 및 혼화재 혼입 유무에 관계없이 철근부식 면적율은 모두 감소하였다. The purpose of this paper is to investigate the coeffecient of permeability and the properties of corrosion of steel in concrete containing chloride.

VOCs (Volatile Organic Compounds) have been produced commercially and used for many purposes in the chemical industry including the manufacture of herbicides, plastics, and solvent. Their emissions affect the change of climate, the growth and decay of plants, and the health of human beings and animals. Therefore it is necessary to limit and control of VOC emission. There are various removal technologies of VOCs, such as catalystic oxidation, biofiltration, Adsorption, Thermal oxidation and Menbrane separation. In this study, we examined both source and components of odor and VOC pollutants emitted from Jeonju and Iksan industrial Area. According to the results, the main VOCs used in the two industrial Area were benzene, toluene, chloroform, methanol, methylene chloride, xylene, ethyl ethyl ketone etc. Especially, hydrogen peroxide and methanol were extremely used in these complex. The regulation of VOC will be more strict within near future. Therefore, this research work will be applicable removal efficiency of VOC emitted from Jeonju and Iksan industrial Area as a fundamental data.

We examined odor concentration during two seasons(fall and winter). The results were as follows : We confirmed the concentration of H₂S, MM, DMS were high. And especially DMA, TMA and i-PA were detected highly in fall and odor indices of those were more than 1, so we confirmed those materials were odor origin materials, but did not detected those materials in winter. The concentrations of n-butylicacid and MEK in VOCs in winter were higher than fall. Therefore we think that examination odor materials with temperature are very important. The concentrations of DEA, i-BA and methanol, methyl ethyl ketone(MEK), methyl cyclo hexane, toluene, and stylene were not exceed minimum sensitive concentration, but those are presumed odor potential material. The odor origin materials in Kunsan industrial complex in fall were H₂S, DMA, TMA, i-PA, n-butylicacid, and the odor potential material were MMA, sec-BA, methyl ethyl ketone(MEK). The odor origin materials in Kunsan industrial complex in winter were H₂S, MM, DMS, n-butylicacid, and the odor potential material were DEA, i-BA, methyl ethyl ketone(MEK), methyl cyclohexane. The dilute magnification in Kunsan industrial complex in fall were examined DMA 10, TMA 3 and total of those was 13, and that in winter were examined H₂S 3, MM 2, DMS 2 and total of those was 8. But the regulation of boundary of factory in industrial complex is <20. The number of odor intensity(1.0 - 2.0) were that H₂S was one in fall and four in winter and therefore that of total five. And the number of odor intensity(1.0 - 2.0) of TMA was four in fall. Generally a civil appeal occur that odor intensity is more than 2.0.
