MANUFACTURING METHOD OF CONCRETE KNEADED ON SITE
To provide a manufacturing method of concrete kneaded on a site: which does not require to construct an erosion control dam by installing a construction road which a large vehicle (for example, a 10 tons dump and a large ready-mixed concrete vehicle) can pass in a planned place of an erosion control dam, manufacturing concrete at a ready-mixed concrete plant in advance, and transporting the concrete using the large vehicle; and which does not cause any trouble in a supply system of ready-mixed concrete when transportation is not finished within a transportation time of 90 minutes or less regulated in JIS even though many erosion control dams are constructed in places separated from a ready-mixed concrete plant in recent years.SOLUTION: Provided is a manufacturing method of concrete kneaded on a site, in which materials of concrete kneaded on a site are made by including a fine aggregate and a coarse aggregate that are packed, packed cement, and water 5 for kneading and an admixture 6 diluted with the water respectively stored in a storage tank, and the materials of concrete kneaded on a site are kneaded on a construction site.SELECTED DRAWING: Figure 1
【課題】砂防堰堤計画箇所に大型車（例えば、１０ｔダンプ、大型生コン車）が通れる工事用道路を設置し、生コン工場であらかじめコンクリートを製造し、このコンクリートを前記大型車で運んで砂防堰堤を構築することを必要とせず、また、近年、砂防堰堤を構築する箇所が生コン工場から遠方の箇所が多くなってきて、そのため、ＪＩＳで規定している９０分以内の運搬時間が満足できずに生コンの供給システムに支障をきたすとのことがない現場練りコンクリートの製造方法を提供する。【解決手段】パック詰めされた細骨材及び粗骨材と、パック詰めされたセメントと、各々貯留槽に貯留された混練り用の水５及び該水で希釈された混和剤６とを有して現場練りコンクリート材料を構成すると共に、該現場練りコンクリート材料を施工現場で混練りすることを特徴とする。【選択図】図１
