Recently, there has been a growing interest in reducing greenhouse gases in all industrial fields. In the construction industry, studies have been conducted for the use of high-volume fly ash concrete to replace cement with fly ash. Quantitative measurements of cement hydration and fly ash reactivity enable a clear understanding of the strength development mechanism of high-volume fly ash concrete. It is very difficult to describe the reactivity in a simple way because the hydration and pozzolanic reactions of cement paste containing fly ash are very complex and the composition of the hydration product cannot be accurately determined. This study investigated the hydration and mechanical properties of high volume fly ash (HVFA) cement according to the substitution rate of fly ash (FA). The hydration degree of cement and the reactivity of FA were evaluated through the selective dissolution method and the non-evaporable water content of the paste according to age. In addition, compressive strength was measured using HVFA mortar specimens according to age. As a result of the experiment, as the substitution rate of fly ash increased, the hydration degree of cement increased, but the reactivity of FA decreased.

The purpose of this study is to analyze whether the cosmetic interest of middle school female students(n=126) is related to purchase satisfaction by using purchase behavior and informatization level as control variables. Based on the research model, three hypotheses were set and statistical tests were conducted. The results of this study are as follows. First, middle school female students used cosmetics from elementary school and cosmetics education was requested from elementary school. Therefore proper early education on cosmetic use is needed. Second, the degree of interest and purchasing behavior of cosmetics was positively correlated with the purchase satisfaction of cosmetics. Third, the purchasing behavior of cosmetics was found to have a more effect on purchase satisfaction than the cosmetics interest. Especially, 'cosmetics purchase behavior' had a moderating effect on purchase satisfaction. Fourth, there was no difference in the average among the grades about cosmetics category(cosmetic interest, purchase behavior, informatization level, purchase satisfaction). This study needs to pay more attention to cosmetics purchasing behavior, which has the greatest effect on the satisfaction of cosmetics purchasing among middle school girls, and suggests that further studies will be continued to expand the range and ages in the future.
