This study deals with the Hydrated Ability of the Ready-Mixed Concrete's Sludge which is the recycling technology of that sludge. The experiment gathers sludge from Ready-mixed factory. shatters these into pieces in dry condition and understands the differences between current using Portland cement. And then. this examines the possibility of the recycle as a bonding agent through the Compressive Strength and considers the recovery of the hydration. This experiment concludes the same Chemical Composition with the normal Portland cement. while. under the appropriate procedure in hydration recovery. this sludge can be used as the bonding agent in cement. The chemical composition of solid Remicon sludge shows that it has 1.8 times $SiO_2$ than the normal Portland cement. meaning lots of aggregate in Remicon sludge. Also. the specific gravity of Remicon sluge increases with the rise of Baking Temperature and has no difference between 2.77 and 2.94. The mortar flow used for combining the baking material of Remicon sludge does was not changed and is the highest between $750^{\circ}C{\cdot}120min\;and\;800^{\circ}C{\cdot}180min$. Additionally. the Compressive Strength increases with the age, certifying the same Hydrated Ability like cement and the best condition for hydration is $750^{\circ}C{\cdot}120min.$

It is a world wide tread for museums to become specialized museums emphasizing their characteristics, but Seongbo museums(museums that preserve Buddhist artifacts) are more general and show no specialization or characterization. The purpose of this study is to emphasize the special character of the Seongbo museum which manages and maintains sacred Buddhist cultural artifacts, and to understand the architectural characteristics of the building distribution and interior composition to implement a more systematic spatial composition plan. For our analysis we selected 6 currently operating museums as our subjects, and analyzed the characteristics of their spatial composition through their plans including the plot plans and ground plans. As a result, we found that most of them were small scale museums, and that the character and rank of each building changed according to its positioning. In terms of areas, the museums consisted of exhibition areas, storage areas, maintenance areas, and other miscellaneous areas and were lacking areas for research and education. It is necessary for these museums to possess facilities for managing these cultural artifacts as well as adequate exhibition and storage spaces. Seongbo museums, which are connected with Buddhist temples, must possess differentiated preservation and maintenance methods unlike museums dealing with artifacts that need only be preserved, and must have an area plan suitable to the characteristics of the various artifacts near and around the temple so as to help build our Buddhist cultural heritage in a systematic and continuous matter.

After the introduction of the 7th education program, educational facilities have been requested to change to face new curriculums and have been planned. The purpose of this study is to fill up a gap between the study of education facilities, building planning and real educational spot and also find difference of plan composition by analyzing latest middle school floor plans. In this regard, floor plans of 8 middle schools proposed in LH design competition is compared and analyzed in this study. To sum up this analysis, the guide lines suggested from Korean educational development institute(KEDI) has not been followed in many building planning. For subject classrooms, guide lines from KEDI were ignored and support facilities did not planned as necessary space calculated through scale estimation program. To select a planned proposal in the future, demand of scale estimation, various studies, real educational spot and etc. should be reflected.

This study was conducted as part of research and development of high-strength grout. Accordingly, dolomite aggregate was used as a filler incorporated into the high-strength grout. Dolomite aggregate has a disadvantage of increasing the viscosity of the grout due to higher generation of fine powder than other aggregates. Accordingly, in this experiment, it was confirmed that the viscosity, flow time, and flow of high-strength grout change according to the volume composition ratio of dolomite aggregate and cement-based material. All experiments were conducted based on the Korean Industrial Standard KS F 4044, and the mixing factor was applied according to the composition ratio of the binder and the filler. In the experiment, the amount of fine powder contained in the dolomite aggregate rather than the silica sand used in the past is grasped, and after mixing with the grout accordingly, the mixture is proceeded to measure the viscosity in an unhardened state. In addition, the flow and flow time of the grout are evaluated according to the viscosity. As a result of the experiment, it was confirmed that the viscosity and flow time decreased and the flow increased as the volume composition ratio of the dolomite aggregate to the cement-based material increased.

Waste Concrete Powder will be generated during the manufacture of construction waste as recycled aggregate Waste concrete. The main component of the waste concrete Powder is a silica-based composition 51% SiO₂, waste concrete cement-based composition Al₂O₃ 10%, CaO 26% component are contained. The material is silica sand of PHC piles should experiment by replacing the Waste Concrete Powder. The compressive strength results are as follows. 25% when the Silica was replaced 32.5Mpa, when 50% have replaced 43.4Mpa, when 75% have replaced 45.3Mpa was measured. Compared with the non-replaced test sample it appears that the strength increases. Therefore, it is determined that the practical use of the PHC piles by replacing silica via this experiment is possible.

The paradigm of contemporary times became different from paradigm of modem times. The change of paradigm is caused by the side effect of paradigm of pre-times. It could be said that contemporary paradigm is pluralism. In the forms of contemporary building and interior design, the informal form is the result of pluralism. This study is researching and analyzing the informal design tendency in the interior space composition of contemporary architecture. the 1950's free form movement, 1960's Informal movement and pluralism after 1970's affected the latest informal forms. The tendencies of contemporary informal design are organic-degital tendency and deconstructive tendency. Along this two kinds of tendencies, I studied the specific characters in expression and analyzed some natural-degital, deconstructive building.
