Modern people come to have high standard and variety need for the oneself expression these days. This phenomenon also, appears in the house space clearly. There are design characteristics in an element expressing a lifestyle and personality in the house space and a living room is the space that is important at time to do a design characteristics plan. Therefore, this study is going to analyze the design characteristics of the apartment house which is a representative house type these days. Concretely, there are design characteristics that a color, an Image, a style. This study used questionary survey from June 10, 2008 to July 9. The color analyzed a color and tone through a color palette of PCIS and the living room image used SD(semantic differential method) method by a concrete analysis method. The result of the analysis were as follows; 1) Various colors and tone were prefer in a house future than the house where lived in. 2) It was done prefer to 'comfort' image for the future living room image in the future but 'provocative' image and 'splendid' were not done a choice 3) A 'modern style' was done prefer to of with a house living room style in the future.

Disposal of industrial waste in cities where municipal authorities permitting higher floor area ratio coupled with increasing living standards, a lot of demolition waste is being generated. Its disposal is a challenge particularly in megacities where no landfills are available. The ever-increasing cost of building construction materials also necessitates consuming demolition wastes in a useful manner to save fresh natural raw materials. In the present work, the crushed waste glass is used in high-strength concrete as a partial replacement of fine aggregate. The control concrete of grade M60 was proportioned following BIS 10262-2009. The crushed waste glass has been used as a partial replacement with varying percentages of 10, 20, 30, and 40% by weight of fine aggregate. Experimental tests were carried on the fresh and hardened state of the concrete. The effect of crushed waste glass on the workability of the concrete has been investigated. Non-destructive tests, acid attack tests, compressive strength, split tensile strength, and X-ray diffraction analysis was carried out for the control concrete and concrete containing crushed waste glass after 7, 28, and 270 days of normal curing. The results show that for the same w/c ratio, the workability of concrete increases with increasing replaced crushed waste glass content. However, the decrease in compressive strength of the concrete after 28 days of normal curing and further after 28 days of acid attacks, up to 30% replacement level of fine aggregate by the crushed waste glass is insignificant.

In the 1970's, the environmental preservation is out of public issue, caused by rapid economic growth and industrialization. When the people's living standard Is grows, they aware of the environmental importance. In modern times, the environment preservation is global tendency and self social awareness is arise. Measures to the environment preservation and pollution is going on study. One measure is recycling and reuse of by product and it is already developed in some advanced country. But, the study about by product reuse is just beginning in domestic. The purpose of this study is reusing copper slag by product which produced in the copper refining process-as fine aggregate for developing high strength concrete. Concrete nix and properties, the result of mock up test for site application are analyzed.

In this study, the quality properties according to the ratio of magnesia and potassium phosphate of the magnesia composite were evaluated to control the quality of the parent material in terms of materials when designing living concrete panels. The quality properties are 7 levels (30, 35, 40, 45, 50, 55 and 60%) for W/B, 4 levels for P:M (1:0.5, 1:1.0, 1:2.0 and 1:3.0 vol. %) was prepared and evaluated. As a result of evaluating the flow of the magnesia complex, as W/B increased, the flow showed a tendency to increase, and the flow showed a tendency to decrease as the P:M increased. As a result of the evaluation of the compressive strength of the magnesia composite, the strength showed a tendency to decrease as P:M increased. In addition, it was confirmed that an optimal P:M ratio exists.
