Construction of the Effective Use System for Concrete Waste and Construction Soil

1.九州地区的工业废弃物和建筑土壤的状况对国土交通省的“副产品调查”数据和九州地区建筑副产品的现状进行了调查。因此，列举了这些问题，以促进有效利用建筑副产品。混凝土废弃物和建筑土的有效利用制度的探讨作为有效利用的政策，从“减量化”、“再利用”和“再循环”的角度对该制度进行了探讨。特别是对混凝土废料作为混凝土骨料进行了研究。为了建立该系统，不应该只检查混凝土废物的使用情况，而需要在生命周期流程的所有阶段（规划、设计、施工和拆除）考虑“减少”、“再利用”和“再循环”。通过这些试验，对混凝土废料的循环系统进行了研究， ...更多信息 wn。然后，以实例说明了建筑土的“减量化”、“再利用”和“再循环”技术，说明了信息系统建设的重要性.混凝土废料有效利用技术的探讨（1）基层材料的应用为了提高混凝土废料的附加值，通过对混凝土废料破碎方法的改进和基层材料等级的提高，说明了基层材料应用的可能性。（2）再生骨料的质量评价及再生骨料混凝土的特性对各种再生骨料进行了物理性能测试，了解再生骨料的质量。在此基础上，提出了了解再生骨料混凝土性能的简易试验方法，并从再生骨料混凝土的性能和取代率两个方面对再生骨料混凝土的性能进行了研究。结果表明，再生骨料作为构件按要求的性能使用，其使用范围的扩大是可以预期的。少

1. The state of Industrial waste and the construction soil in Kyushu regionThe data of "A fact-finding of by-product" made by Ministry of Land, Infrastructure and Transport, and a present state of construction by-product in Kyushu region was investigated. As a result, those problems were enumerated in order to promote effective use of a construction by-product.2. An examination on the effective use system of concrete waste and the construction soilAs a policy of effective use, that system was examined from the point of view of "reduce", "reuse" and "recycle". Especially the concrete waste was examined to use as concrete aggregate. In order to build up that system, only the usage of a concrete waste should not be examined, but it is necessary to examine based on taking into consideration "reduce", "reuse", and "recycle" in all the stages of the lifecycle flow (plan, design, construction and dismantle). As a result of those examinations, the circulation system of a concrete waste was sho … More wn. Then, the techniques for using construction soil for "reduce", "reuse" and "recycle" were given as actual examples, the importance on constructing an information system was shown.3. An examination on the effective use technique of concrete waste(1) Application for the base course materialIn order to raise the added value of concrete waste, the possibility for applying the base course material was shown by improving of crush methods on concrete waste and the grade of the base course material.(2)The quality evaluation of recycled aggregate and characteristics of recycled aggregate concreteThe physical property tests for various kinds of recycled aggregate were performed ; the quality of recycled aggregate was understood. Then the simple test method for understanding those qualities was proposed.Moreover, characteristics of recycled aggregate concrete were examined considering those qualities and replacement ratio with natural aggregate. It is shown that the use expansion of recycled aggregate is expectable, by using as a member according to a required performance. Less
