This study aims to analyze the lifecycle and lifestyle of the elderly and apply it to modular housing equipped with economic feasibility and flexibility to make housing plans for the elderly. To attain the goal, first, this study divides the behavior of the elderly into two types, the independent type and dependent type. Second, the elderly housing characteristics are analyzes. Third, this study organizes the flexible elements of housing planning. Fourth, a user survey are conducted regarding elderly housing planning elements. Fifth, based on the elements of housing plans for the elderly analyzed, this study suggests a prototype for flexible housing. In conclusion, this study proposes prototypes for independent couples, independent singles, dependent couples, and dependent singles. With this research, it will be possible to plan module units for each room applying the changes of behavior and lifestyles of the elderly and apply flexibility housing plans so as to improve dwelling environment for the elderly afterwards.

In this paper. variations of the period of cold weather concrete in Korea are discussed based on the climate data of Korean Meteorological Adminstration(KMA). Determination of the period of cold weather concrete with the region is done by following Korean Concrete Institute(KCD, American Concrete Institute(ACD and AIJ(Architectural Institute of Japan(AIJ) specification. Present study is compared with previous study done by the authors. Period of cold weather concrete is found to increase with high altitude and in-land and mountain area. Period of cold weather concrete by present study is shorted compared with that of previous study by about 3~6 days regardless of applied specification. Especially. the period of cold weather concrete at southern region near sea is reduced remarkably compared with that of previous study. This is due the rise of mean air temperature by global warming. In the scope of present study, period of cold weather concrete is provided with table and map diagram.

In this paper, field application test of super retarding agent is discussed to reduce hydration heat of mass concrete considering setting time difference of super retarding agent by using horizontal placing layer in Megatrium building construction field at Yongsan in Seoul. Properties of fresh and hardened concrete and hydration heat are investigated, According to test results, both base concrete and flowing concrete meet the requirement of designed slump and air content, although some variances exist. As for compressive strength, it also satisfies the specified strength the consumer need in base concrete and hardened concrete. As for hydration heat, highest temperature of middle section in top placing layer is 65v at 28hours, and in bottom placing layer is 73℃ at 68hours.

According to the test, An increase of super-retarding-agent (SRA), which combined the SRA with admixture, delayed initial and final setting time. Interestingly control concrete incorporating only admixture also retarded setting time. In addition concrete, adding combination of the SRA and admixture simultaneously, exhibited considerable results, due to the absorbing, pozzolanic and potential hydraulicity reaction of the admixture. Overall, to secure initial setting time as control concrete does, particular coefficient value considering the properties of each materials, should be applied, before it is placed in the field construction.

This paper investigated the temperature history of mass concrete mock up structure considering different heat generation by varying with mixture proportion. Setting time difference between high early strength mixture (E-P) and retarding mixture (R-F30) was 14.5hours. Incorporation of 30% of fly ash contributed to 10℃ of hydration heat reduction. In generally used A and B combination, bottom concrete shows earlier hydration, while C~G combination showed reverse tendency and thus, this method can reduce the crack occurrence. For compressive strength, the mixture combination of S-F30(top section), R-F30(bottom section), which incorporate fly ash exhibits a reduction in compressive strength by as much as 5~10MPa compared with other mixture combination. There's no remarkable difference of strength development with and without fly ash based on the results of core test. Therefore, heat generation difference method has beneficial effect on reducing crack induced by hydration heat resulting from heat generation difference between surface and center section.
