건ㆍ습식 복합 분체이송 뿜칠시공시스템의 재료분리저항성에 관한 실험적 연구 = An Experimental Study on the Material Separation Resistivity in Complex Dry and Wet Process Machinery System

다국어 초록 (Multilingual Abstract)

Recently repair and reinforcement of large-sized reinforced concrete structures have been interested, because of their early deterioration and durability deterioration as time goes by. And adequate repair method has been required urgently in order to cope with these repair works which are growing bigger and larger. As one of appropriate repair method, spraying method has been discussed and applied job site recently.
This study" is focused on the examination of quality stabilization dry mortar which is transferred mechanized and automated dry and wet compounded system.
It is investigated that two important equipments are transfer hose wave and dry mixing hopper to increase material separation resistivity. In case of material transferred hose wave and dry type mixing hopper, quality stabilization shows much better result than not transferred. And appropriate transfer pressure and distance to decrease material separation is 0.8~0.9 bar and 150m.
It is believed that the effect of shortening term of works and cost reduction will be expected by this mechanized and automated concrete repair system.
