 note = {When the concrete waste is recycled as the aggregate, the concrete waste is generally carried to the plant and the recycled aggregate is manufactured. However, in this method it needs significantly much energy and causes much CO₂ when the concrete waste is carried to the plant. Therefore, we need to consider about environment to study on recycling of concrete waste in site. In this study, we investigated, appropriate mix proportions used recycled coarse aggregate, properties of fresh concrete, pumpability, and properties of hardened concrete in case recycling of concrete waste in site. As a result, we proposed following process. (1)When mortar is manufactured at the plant, we add amount of additional water absorption of the recycled coarse aggregate into the water content. (2)The mortar is carried from the plant to the site. (3)The recycled coarse aggregate is manufactured in site and mixed to the mortar. To compare with recycled aggregate concrete manufacturing at plant it is same as this method of slump, pumpability, compressive strength, tensile strength, elastic modulus of elasticity, properties of chloride penetration., 本研究では，モルタルを現場に搬入し，気乾状態の再生粗骨材を使用する場合，気乾状態の再生粗骨材の有効吸水率分の水量を補正したモルタルに，再生粗骨材を投入して製造したコンクリートの，フレッシュ性状および硬化性状，また，スランプの経時変化およびポンプ圧送性について検討を行った．},
