To provide a spray material blending system capable of precisely determining W/C of spray material and easily adjusting it when blending the spray material at a construction site of a spraying operation.SOLUTION: A spray material blending system (100) of the present invention comprises a sand supply device (3) for weighing and supplying sand, a surface water rate measuring device (21) for measuring the surface water rate of the supplied sand, a cement supply device (5), a device (water tub 8, pump 9) for supplying water, a spraying device (11) for mixing water, sand and cement and supplying it to a spraying nozzle (14) via a spray material hose (13), and a control device (30). The control device (30) has a function of determining a surface water rate in the supplied sand, and a function of calculating the moisture amount of the sand and controlling the amount of water supplied to the difference between the moisture amount necessary for compounding the spray material and the calculated moisture amount of the sand.SELECTED DRAWING: Figure 1
【課題】吹付作業の施工現場で吹付材を配合する際に、吹付材のＷ／Ｃを正確に決定し且つ容易に調整することが出来る吹付材配合システムの提供。【解決手段】本発明の吹付材配合システム（１００）は、砂を計量して供給する砂供給装置（３）と、供給される砂の表面水率を計測する表面水率計測装置（２１）と、セメント供給装置（５）と、水を供給する装置（水槽８、ポンプ９）と、水、砂、セメントを混合し吹付材ホース（１３）を介して吹付ノズル（１４）へ供給する吹付装置（１１）と、制御装置（３０）を備え、制御装置（３０）は、供給された砂における表面水率を決定する機能と、砂の水分量を計算して、供給される水の量を、吹付材の配合に必要な水分量と前記計算された砂の水分量との差に制御する機能を有する。【選択図】図１
