APPARATUS FOR FEEDING ADDITIVE FOR CIVIL ENGINEERING

To provide an apparatus for feeding additive for civil engineering which can feed a preset amount of an additive for civil engineering without depending on temperatures.SOLUTION: An apparatus 10 for feeding an additive for civil engineering comprises a liquid feed control part 17. The liquid feed control part 17 is configured to: acquire viscosity related information of additive A for civil engineering; calculate a liquid feed time of the additive A for civil engineering which is required for a liquid feed execution part 14 to feed a preset amount of the additive A for civil engineering with viscosity corresponding to the acquired viscosity related information; cause the liquid feed execution part 14 to start feeding the additive A for civil engineering; and, when the calculated liquid feed time elapses after the start of feeding the additive A for civil engineering, cause the liquid feed execution part 14 to stop feeding the additive A for civil engineering.SELECTED DRAWING: Figure 1 【課題】気温によらず土木用添加剤の設定量を供給することができる土木用添加剤供給装置を提供する。【解決手段】土木用添加剤供給装置１０は、送液制御部１７を備える。送液制御部１７は、土木用添加剤Ａの粘度関連情報を取得し、その取得した粘度関連情報に対応する粘度の土木用添加剤Ａの設定量を送液するのに必要な送液実行部１４による土木用添加剤Ａの送液時間を計算し、送液実行部１４に土木用添加剤Ａの送液を開始させ、土木用添加剤Ａの送液を開始してから計算した送液時間が経過したとき、送液実行部１４による土木用添加剤Ａの送液を停止させる。【選択図】図１
