【発明の詳細な説明】 （産業上の利用分野） 本発明は水中盛土等を構築する場合に使用する盛土材に
関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an embankment material used when constructing an underwater embankment or the like.
（従来の技術） 鉄筋コンクリート等のコンクリート構造物、又は水中盛
土を構築する場合に使用されるコンクリート材はセメン
ト、水、骨材以外に混和材料を混入することにより、ま
だ固まらないコンクリート及び硬化したコンクリートの
性質を改善するか、或は新たな性質を付与して品質精度
や作業性等の向上を図ってきた。(Prior Art) Concrete materials used for constructing concrete structures such as reinforced concrete or underwater embankment are concrete, which has not solidified yet by mixing admixtures other than cement, water, and aggregate, and hardened concrete. Have been improved or the new properties have been added to improve quality accuracy and workability.
（発明が解決しようとする課題） しかし、上記の混和材料は使用量によって、薬品的に少
量用いる混和剤と、比較的多量に用いる混和材とに大別
されるが、これらの混和剤及び混和材は水中盛土を構築
する盛土材に用いることはいずれも高価である。(Problems to be Solved by the Invention) However, the above admixture materials are roughly classified into admixtures used in small amounts chemically and admixtures used in relatively large amounts according to the amount used. The materials are expensive to use as embankment materials for constructing underwater embankments.
また、水中盛土の盛土材にこれらの混和剤及び混和材を
用いた場合、所定の効果を得るには多量に用いなければ
ならなかった。Moreover, when these admixtures and admixtures were used as the embankment material for underwater embankment, a large amount had to be used to obtain the desired effect.
本発明はこのような問題に鑑みてなされたものであり、
その目的は安価で、しかも少量の混和材で有効に効果を
発現できる盛土材を提供することである。The present invention has been made in view of such problems,
The purpose thereof is to provide an embankment material that is inexpensive and can effectively exhibit the effect with a small amount of the admixture.
（課題を解決するための手段） 以上のような課題を達成するための、本発明の盛土材は
固化材と、粗骨材と、細骨材と、あるいはこれらの一部
と、水および火山灰質粘性土を混練して製造した構成に
することである。(Means for Solving the Problems) In order to achieve the above problems, the embankment material of the present invention is a solidifying material, a coarse aggregate, a fine aggregate, or a part thereof, water and volcanic ash. It is to make a structure produced by kneading clayey soil.
（作用） 一般に、盛土材は骨材間空隙をセメントゲルが充填する
ことにより強度を発現するためには、前記骨材間空隙を
小さくするか、或はセメントゲル量を多くすることが必
要である。(Function) Generally, in order to develop strength by filling the inter-aggregate voids with cement gel in the embankment material, it is necessary to reduce the inter-aggregate voids or increase the cement gel amount. is there.
本願発明における前記火山灰質粘性土は１μｍ以下のコ
ロイド分、粘土分、シルト分、細砂を含有する粘土分布
の広いものであり、このような火山灰質粘性土を盛土材
に混合すると、火山灰質粘性土が骨材間空隙を小さくす
ると共に、火山灰質粘性土の微粒分がセメントゲルの中
に取り込まれて見かけのセメントゲル量が増加して強度
が増加する。The above-mentioned volcanic ash cohesive soil in the present invention has a wide clay distribution containing colloids, clay, silt, and fine sand of 1 μm or less. When such volcanic ash cohesive soil is mixed with embankment material, volcanic ash The cohesive soil reduces the voids between the aggregates, and the fine particles of the volcanic ash cohesive soil are taken into the cement gel to increase the apparent cement gel amount and increase the strength.
さらに、火山灰質粘性土の微粒子の保水作用により、材
料の流動性が改善されると共に、ブリージングによる水
分の分離も少なくなる。Furthermore, the water retention effect of the fine particles of the volcanic ash cohesive soil improves the fluidity of the material and reduces the separation of water due to breathing.
（実施例） 以下、本発明を盛土材に適用した実施例について説明す
る。(Example) Hereinafter, the Example which applied this invention to the embankment material is described.
本発明の実施例においては表−１のように、山砂1190kg
と、セメント120kgと、水480kgと、火山灰質粘性土90kg
とを混合した盛土材と、山砂1469kgと、セメント143kg
と、水388kgを混合した従来の盛土材の一週強度、流動
性リージング率を測定し、その結果を表−２で比較し
た。In the embodiment of the present invention, as shown in Table-1, 1190 kg of sand
, Cement 120kg, water 480kg, volcanic ash cohesive soil 90kg
Embankment material mixed with and 1469 kg of sand and 143 kg of cement
And the weekly strength and fluidity leasing rate of a conventional embankment material mixed with 388 kg of water were measured, and the results are compared in Table-2.
ここで火山灰質粘性土は１μｍ以下のコロイド分、粘土
分、シルト分、細砂を含有する粘土分布の広いものであ
り、東京都八王子市で採取した立川ロームが使用され
た。Here, the volcanic ash cohesive soil has a wide distribution of clay containing colloid, clay, silt, and fine sand of 1 μm or less, and Tachikawa loam collected in Hachioji, Tokyo was used.
また、セメントは高炉セメントＢ種が使用された。Blast furnace cement class B was used as the cement.
以下に示す実験結果から本願発明の効果を確認すること
ができた。The effects of the present invention could be confirmed from the experimental results shown below.
本願発明の盛土材は、単に水中盛土の盛土材のみでな
く、低強度のコンクリート構造物のコンクリート材とし
ても使用することも勿論可能である。The embankment material of the present invention can be used not only as an embankment material for underwater embankment but also as a concrete material for a low-strength concrete structure.
（発明の効果） 本発明は固化材と、粗骨材と、細骨材と、あるいはこれ
らの一部と、水および火山灰質粘性土を混練したことに
