Abstract
The aim of this study was to analyze the physical properties of bottom ash from municipal recycling Solid waste incineration (MSWI) bottom ash and lightweight aggregate used to investigate the possibility Structural concrete and road construction, according to the Korean Industrial Standards (KS) bottom ash aggregate. Samples, results in resource recovery facilities "A" and "B" in the collection were taken from MSWI bottom ash Both samples were not satisfied
with the quality of the particle size. In particular, failed to comply with two samples Criteria for structural concrete physical and chemical properties of the light. on the other hand, The bottom meets the physical properties of bottom ash for road construction quality ash samples. Therefore, Construction Bottom ash can be a suitable method for the recycling of aggregate recycling, provided It is the most suitable pre-treatment as a screening process for bottom ash.

I. INTRODUCTION
Seoul, neck "2030 Seoul kind of low-carbon, green growth" Life tables (zero waste) in the implementation of resource recycling Tue pushing for zero waste land. Municipal waste Recycling, efficiency gains and environmental pollution problem sites on Earth And to address the driving force of the new value and growth Zero on the world's list to promote waste 1). Table 1 is a view in the presence and treatment of municipal waste As shown in Table Open and donations, is low to the ground And holding a tendency to increase sogakryang 2). sogakryang It also will increase the amount of ash, which should increase Increase in recycling and ash over the country Specifically, even when domestic recycling incinerator ash as a resource There is a need to discuss this project. Developed countries If you have already applied to the use of recycled and burned down to ashes no. In the US, the asphalt road solidification And packaging, used for soil conditioner Japanese ash Back Ceramic Eco Cement screen is actively researching he said. In Europe, road earth, a bank, building materials Especially used in France, 90% of the floor burned Used 3 is generated.). Some companies in Korea Bricks, blocks, tiles, etc. Use incineration Floor Building But accurately produce the amount they are doing and discourage recycling Or compared to the 3-6), a situation that is out of business very poor condition. In fact, municipal solid waste incineration bottom The actual recycling unclear regulations and standards for re- As a situation where thousands have faced many challenges. The study, incineration bottom ash created to facilitate the recovery of resources Legal standards, whether by minute according taken for recycling Seats and uses a wide range of recycled original Kindle floor Civil structural design and light weight for the Bottom Ash Aggregate How to perform a study assessing the appropriate standard Respectively.

1. Sampling
In this study, resource recovery facility located in Seoul 'A' 'B' gene targeting experiments incineration bottom ash to have taken This was performed. The test sample is determined on the basis of waste The sampling was conducted in accordance with ES 06130.b, collected, 7 of 10 ilgan incineration bottom ash cool features It was in a dry place.
