Recently, it is certain that the increase of heating and cooling energy consumption by radical change in climate condition has caused serious problems related to environmental and energy concerns associated with increase of fossil fuel usage and carbon dioxide production as well as global warming. Therefore, various actions to reduce greenhouse gas and energy consumption have been prepared by world developed countries.
Our government has also been trying to seek energy control methods for houses and buildings by proclaiming political polices on low-carbon green growth and construction and performance standards for environment-friendly housing. The energy consumption by buildings approximately reaches 25% of total energy consumption in korea, and the increasing rate of energy consumption by buildings is stiffer than that of the other industries. The biggest consuming building element is building facade. While lots of research projects for reducing energy consumption of the facade have been conducted, few research projects on concrete covering more than 70% of outsider of buildings has been tried.
This research presents here a study to improve the insulation property of structural concrete by calcined diatomite powder and lightweight aggregate with experimentally reviewing the physical, mechanical and thermal conduction characteristics of the concrete. The result of experiment showed calcined diatomite powder 10% series mixtures resulted in positive workability, compressive strength and resulted of thermal conductivity, which was the improvement of 43% compared to plain.
In the future, various studies must be progress that review of various insulation performance improvement materials, review of performance and durability of the structure in order to field application and improve insulation performance of concrete.
