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

1.九州地区工业废弃物和建筑土壤状况调查调查了国土交通部的《九州地区建筑副产物实况调查》和九州地区建筑副产物现状。因此，列举了这些问题，以促进建筑副产品的有效利用。对混凝土废料和建筑土有效利用制度的审查作为一项有效利用的政策，从“减少”、“再利用”和“回收”的角度对该制度进行了审查。特别是对混凝土废料用作混凝土骨料进行了试验研究。为了建立这一体系，不应该只审查混凝土废物的使用情况，但有必要在考虑到生命周期流程的所有阶段(规划、设计、施工和拆除)中的“减少”、“再利用”和“回收”的基础上进行审查。作为这些检查的结果，混凝土废料的循环系统是Sho…更糟的是。给出了利用建设用地进行“减量化”、“再利用”和“再循环”的技术实例，说明了其在信息系统建设中的重要性。混凝土废料有效利用技术的研究(1)基层材料的应用为了提高混凝土废料的附加值，通过对混凝土废料粉碎方法和基层材料级配的改进，论证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试验，了解了再生骨料的质量。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，并对再生骨料混凝土的特性进行了考察。结果表明，按性能要求作为再生骨料的构件，再生骨料的用途扩展是可以预期的。较少

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
