Study on 3 Dimension Geometrical Modeling of Porous Concrete and Application to Design and Construction

本研究旨在建立多孔混凝土的广义理论、施工及质量控制方法。由此，成功地提出了多孔混凝土体积变化特性的几何模型，以及作者先前提出的强度和抽水能力的几何模型。设计了一种用于多孔混凝土施工的原型浇筑机和精整机，并对其适用性进行了评价。利用振动能量的概念，提出了一种控制多孔混凝土压实性能的方法。最后，根据研究结果，总结出多孔混凝土的施工标准。

Purpose of the present study is to establish a generalized theory, construction and quality control methods of porous concrete. From the result, a geometrical model of volume change characteristics of porous concrete was successfully proposed, as well as the geometrical models of strength and water pumping ability previously suggested by the authors. A prototype placing machine and a finisher for porous concrete work were devised, and applicability of these machines was evaluated. A method to control compaction performance of porous concrete was proposed by using the concept of vibrating energy. Finally, a construction standard of porous concrete was summarized up, based on the result of this study.
