Concrete is the most commonly used material in construction field and it is the permanent construction material with respect to civil property. But, if concrete loses its alkalinity by CO2 gas, it loses its structural characteristics and results in total collapse in construction field. Therefore. it is needed to be studied the alkali-recovery performance by alkalization agent on carbonated concrete by accelerated carbonation test. In this paper, we investigate recovery performance by impregnating alkalization agent in carbonated concrete, then we evaluate alkali maintenance performance by pH survey in each kinds of finishing materials. The results of this paper can be summarized as follows. 1)Carbonated concrete under pH 10 was recovered its alkalinity to pH 11 at first stage by spreading alkalization agent on its outer surface. 2)After spreading alkalization agent, there is a difference due to types of moreover effect of anti-rust paint and ordinary cement paste were excellent.

Multimedia information includes image information, sound information, character information and various informations. Difficulty follows to look for image which user wants by existent retrieval method. Therefore, introduce MSE(Mean Square Error) by index method for efficient practical use of video information in this research and propose scene change detection retrieval method of video. This image data for diagonal line direction color value of schedule pixel draw, (By j^(*)i matrix to Matrix A, i is frame number, j stored cost that express diagonal line Image height of frame to Matrix A). So that can grasp whole structure of video, do sampling in still image, Made user can grasp whole structure of video, do sampling in still image. Made user grasp scene change point of total video on one eye. If MSE of each frame exceeds critical value, search the frame by scene change.

최세진,임정열,정우성,김완영,김무한 공주대학교 자원재활용신소재지역협력센터 2000 2차년도 센터 사업 성과집 Vol.2000 No.1

This is an experimental study to analyze the usability of fly ash in the tunnel lining concrete. For this purpose, the mix proportion of plain concrete and concrete using fly ash(the replacement of 15 and 30% by weight of cement) to satisfy slump 15cm, air content 5% and compressive strength 270kgf/cm2, was selected. And then tests for slump, setting time, compressive strength, tensile strength, drying shrinkage and adiabatic temperature rise were performed. According to test results, it was found that the concrete using fly ash 15% (FA 15 concrete) was better than the plain concrete and FA 30 concrete. FA 15 concrete was more useful than the others in reducing the drying shrinkage : the drying shrinkage strains of FA 15 concrete after 20 weeks of air drying was lower about 10% than the plain concrete, and lower 6% than FA 30 concrete. And the highest compressive strength after curing for 28 days of 365kgf/cm2 was obtained from FA 15 concrete. This was almost 10-20% improvement in compressive sterngth, compare to the plain concrete and FA 30 concrete. And the effect of 5~7.5℃ of concrete using fly ash for hydration heat reducing was calculated. Therefore, concrete using fly ash 15% (FA 15) was expected to improve the performance of lining concrete.
