Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明はセメントを中心として構成される水硬性組
成物に関する。Description: TECHNICAL FIELD The present invention relates to a hydraulic composition mainly composed of cement.
産業副産物であるスラグはある程度の水硬性を有して
おり、また、フライアッシュあるいはシリカヒューム
は、本質的に無機質であるので、これら副産物の有効利
用を目的としてセメントとの混合により建材等を製造す
ることが広く行なわれている。Slag, which is an industrial by-product, has a certain degree of hydraulicity, and fly ash or silica fume is essentially inorganic, so building materials are mixed with cement for the purpose of effective use of these by-products. Is widely practiced.
しかしながら、上記産業副産物は、シリカ分の他に比
較的大量のアルミ成分を含むため、セメントに対し、あ
まり大量に使用すると、上記アルミ成分に起因して成形
体がもろくなり、十分な強度同上が得られないと言った
問題が有った。However, since the above-mentioned industrial by-product contains a relatively large amount of an aluminum component in addition to the silica content, when used in an excessively large amount with respect to cement, the molded body becomes brittle due to the above-mentioned aluminum component, and sufficient strength and strength are obtained. There was a problem that I could not get.
従って、有効利用と言っても限度が有り、大量消費を
可能とするまでにはまだ改良の余地が有った。Therefore, there is a limit in terms of effective use, and there is still room for improvement before mass consumption becomes possible.
この発明は上記問題点に鑑み、上記三種の産業副産物
を大量に使用しても、成形品の強度も損うことの無い水
硬性組成物を得ることを目的としてなされたものであ
る。In view of the above problems, the present invention has been made with the object of obtaining a hydraulic composition that does not impair the strength of a molded product even when the three types of industrial by-products are used in large amounts.
即ち、この発明の水硬性組成物は普通ポルトランドセ
メント、又は早強セメント等セメント材料１に対し４〜
6.5倍重量部のスラグ、１〜2.5倍重量部のフライアッシ
ュ、0.4〜１倍重量部のシリカヒュームを添加して成る
配合原料に必要に応じ軽量骨材、補強繊維を添加して成
ることを特徴とするものである。That is, the hydraulic composition of the present invention is used in an amount of 4 to 4% for cement material 1 such as ordinary Portland cement or early-strength cement.
6.5% by weight of slag, 1 to 2.5 times by weight of fly ash, 0.4 to 1 times by weight of silica fume It is a feature.
この発明において、セメントは、従来の添加産業副産
物との混合体において、マトリックスに強度発現の一部
を担うと共に、スラグのアルカリ刺激剤として作用す
る。In this invention, cement, in a mixture with conventional additive industrial by-products, plays a part in the strength development of the matrix and acts as an alkaline stimulant for the slag.
また、スラグは上述のセメントと共に水硬性物質とし
て、反応するものであり、従って、セメント１に対し４
〜6.5倍の添加重量部とされる。In addition, slag reacts with the above-mentioned cement as a hydraulic substance.
It is to be added by 6.5 times or more.
なお、４倍より少なくすると、産業副産物としての大
量使用の意義が薄れ、一方、6.5倍量より多くすると、
マトリックスの強度発現に悪影響が出るため、上述の範
囲が適当な添加量となる。If it is less than 4 times, the significance of mass use as an industrial by-product diminishes, while if it is more than 6.5 times,
Since the strength development of the matrix is adversely affected, the above range is an appropriate addition amount.
フライアッシュは、安価であり、大量使用が好ましい
が、これに含まれるアルミ成分により強度発現が阻害さ
れる。しかしながら、フライアッシュによって成形品の
寸法安定性が改良される点に鑑み、その添加量はセメン
トに対し、１〜2.5倍量の重量部とされる。Fly ash is inexpensive and preferably used in large quantities, but its strength is inhibited by the aluminum component contained therein. However, in view of the fact that fly ash improves the dimensional stability of the molded article, the addition amount is 1 to 2.5 times the weight part of cement.
１倍量より少ないと、産業副産物の有効利用としての
意義が薄れ、また、2.5倍量より多くすると強度低下を
来し、不都合が生じる。If the amount is less than 1 time, the significance as an effective use of industrial by-products is diminished, and if the amount is more than 2.5 times, the strength is reduced and inconvenience occurs.
よって上記の添加量とされるのが好適な添加量とな
る。Therefore, the above addition amount is a preferable addition amount.
シリカヒュームは、微粒子の反応性が高いシリカであ
り、上記添加原料により構成されるマトリックスの強度
発現に寄与する。Silica fume is silica having high reactivity of fine particles, and contributes to the development of the strength of a matrix composed of the above-mentioned added materials.
このシリカヒュームによる強度発現効果は、前述のフ
ライアッシュによる強度低下の作用に比し、はるかに優
れており、従って、強度発現に不可欠のものである。The strength development effect of the silica fume is far superior to the strength reduction effect of the fly ash described above, and is therefore indispensable for the strength development.
添加量をセメント１に対し0.4〜１倍量とするのは、
0.4倍量より少ないと上述の強度発現効果が得られず、
１倍量より多くしても、添加量に見合った強度高上は期
待できず、さらに未反応シリカ分に起因するエフロレッ
センスの発生等が生じ、不都合だからである。The reason why the amount of addition is 0.4 to 1 times the amount of cement 1
If the amount is less than 0.4 times, the above-mentioned strength expression effect cannot be obtained,
If the amount is more than 1 time, the strength cannot be expected to be increased in proportion to the added amount, and furthermore, efflorescence due to the unreacted silica component is generated, which is inconvenient.
必要に応じ添加される軽量骨材としては、パーライト
等の天然骨材の他、人工軽量無機質骨材か、補強繊維と
してはパルプ、化学繊維、ガラス繊維等、成形品の使用
目的により適宜任意に選択使用され、その添加量もマト
リックスの強度を低下させない範囲で選択される。Light-weight aggregates to be added as necessary, besides natural aggregates such as pearlite, artificial light-weight inorganic aggregates, or reinforcing fibers such as pulp, chemical fiber, glass fiber, etc. It is used selectively, and its addition amount is also selected within a range that does not reduce the strength of the matrix.
〔実施例〕 次に、この発明の実施例を説明する。Embodiment Next, an embodiment of the present invention will be described.
表１に示す配合にて、水硬性組成物を作成し、 水を加えてスラリーとなし、該原料を丸網抄造機で厚さ
5mmに製板し、メーキングロールより切開後、30kg/c
m2、５秒間の条件でプレス加圧し、常法に従って養生硬
化させた。With the composition shown in Table 1, a hydraulic composition was prepared, The slurry is made by adding water, and the raw material is thickened by a round mesh machine.
30mm / c after making 5mm plate and incising from making roll
Pressing was performed under a condition of m 2 for 5 seconds, and the composition was cured and cured according to a conventional method.
次に、上記板材につき、曲げ強度試験、及び比重を測
定したところ、表２の結果となった。Next, the bending strength test and the specific gravity of the plate material were measured, and the results are shown in Table 2.
なお、表１、表２において、比較例は、産業副産物を
全く添加しない組成物により製板したものを示す。 In addition, in Table 1 and Table 2, the comparative example shows what was made with the composition to which no industrial by-product was added.
この発明は以上説明したように、産業副産物を単独で
セメントに添加した場合に生じる弊害を、他の産業副産
物の添加でおぎない、もって、全体の総量的利用を可能
とし、有効な資源の利用と可能とすると共に、成形体の
強度向上も図れるなど種々の効果を有する。As described above, the present invention does not prevent the adverse effects caused by adding industrial by-products to cement alone by adding other industrial by-products, thereby enabling the total use of the entire product, and enabling effective use of resources. In addition to being possible, it has various effects such as improvement in strength of the molded body.
