Outline of Final Research Achievements

This study investigated the ideal clay environment and materials for invigorating the day-to-day sculpture activities of young children.The clay material model is a waste product emitted from river plants composed mainly of silt particles ranging from 2μm to 20μm in size.It has the following characteristics. 1. The clay has a high level of plasticity appropriate for sculpture play.2. It is also well-suited to intuitive play.
3. It can be easily broken down even when dried out, and has superb water absorption.4. Minerals are the main components, and plants do not grow easily in it.5. It has a low cost.This study used a clay with characteristics similar to this waste product named Super Clay by the researchers for practical applications. From an engineering studies perspective, the structural components required for the clay material were determined to be A2 silica sand, no. 9 silica sand, and sculpture powder mixed together.

Academic Significance and Societal Importance of the Research Achievements

河川プラントから排出される不要土によって構成される「ねんど場」は、扱いやすく子どもの造形活動を活性化する保育教材として意義のある土素材である。また、珪砂と彫塑紛で構成されたスーパークレイは、不要土に匹敵する優れた特性を持つと同時に安定的に供給でき、様々な地域に安価で供給できる優れた特性を持つ土（粘土質土）である。これらの土素材を使用し遊ぶことで幼児の触覚や想像力を豊かにすることが期待される。
