METHOD FOR RECYCLING REBOUND MATERIAL
PROBLEM TO BE SOLVED: To provide a method for recycling rebound material that can save the trouble and costs needed to dispose of the rebound material by recycling the rebound material.SOLUTION: The present invention relates to a method for recycling rebound material that comprises: a recovering step S3 of recovering rebound materials of sprayed concrete; an aggregate manufacturing step S4 of manufacturing recycled aggregates by decomposing mutually sticking rebound materials; a separating and sorting step S5 of separating and sorting fine-grained fractions among the recycled aggregates; a water absorbing step S6 of letting the recycled aggregates absorb water; and a material manufacturing step S7 of mixing the recycled aggregates with a cement-based solidifying material to manufacture a cement-based material.SELECTED DRAWING: Figure 2
【課題】はね返り材を再利用することで、はね返り材の処分に要する手間および費用の低減化を可能とした、はね返り材の再利用方法を提案する。【解決手段】吹付けコンクリートのはね返り材を回収する回収工程S3と、互いに付着したはね返り材を分解して再生骨材を製造する骨材製造工程S4と、再生骨材の中から細粒分の分離選別する分離選別工程S5と、再生骨材に吸水させる吸水工程S6と、再生骨材をセメント系固化材と混合してセメント系材料を製造する材料製造工程S7とを備えているはね返り材の再利用方法。【選択図】図2
