メント配合物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cement mixture for autoclave use, and more particularly to a cement mixture for autoclave use that is a resource-saving, high-strength inorganic building material.
（従来の技術）
従来、オートクレーブ養生によってセメント等の硬化反
応を促進し、硬化物の強度を強くするためのセメント配
合物として、結晶性め珪砂をセメントと同程度の粉末度
まで粉砕して、セメント：珪砂＝５．５ ： ４．５〜
６．５ ： ３．５もしくはＣａｂ／Ｓｉｎｇ＝０．８
〜１．０となるよう混合使用することが一般に行なわれ
ている。(Prior Art) Conventionally, crystalline silica sand was ground to the same level of powder as cement as a cement compound to promote the hardening reaction of cement, etc. through autoclave curing and increase the strength of the hardened product. Cement: Silica sand = 5.5: 4.5~
6.5: 3.5 or Cab/Sing=0.8
It is common practice to mix them so that the ratio is 1.0 to 1.0.
ところで、近年、省資源、及び産業廃棄物の有効利用の
観点より、スラグ又はフライアッシュの水硬性を利用し
、これらをセメント代替品として利用す秦ことが広く提
案され、実施されるに至っている。Incidentally, in recent years, from the viewpoint of resource conservation and effective use of industrial waste, a method of utilizing the hydraulic properties of slag or fly ash and using these as cement substitutes has been widely proposed and implemented. .
しかしながら、既述したオートクレーブ用配合物を最強
強度として、スラグ等の代替物質を添加すると製品強度
は、かなり低下する傾向に有り、例え、オートクレーブ
養生条件を厳格に設定しても充分な強度となし難い問題
が有った。However, if the already mentioned autoclave formulation is the strongest, and an alternative substance such as slag is added, the product strength tends to decrease considerably, and even if the autoclave curing conditions are set strictly, the strength will not be sufficient. There was a difficult problem.
従って、産業廃棄物を利用するにしても、製品の用途に
かなりの制約が有り、汎用性が無い問題が有る。Therefore, even if industrial waste is used, there are considerable restrictions on the uses of the product, and there are problems in that it lacks versatility.
この発明は上記欠点に鑑み、スラグ等の廃棄物を使用し
ても、充分な製品強度が得られ、もって広汎に使用可能
なオートクレーブ用セメント配合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-mentioned drawbacks, the present invention was made with the aim of obtaining a cement composition for autoclaves that can be used in a wide range of applications and has sufficient product strength even when waste materials such as slag are used.
即ち、この発明のオートクレーブ用セメント配合物は、
セメント：シリカ：高炉スラグの配合比が６：３：１〜
３：３：４とした水硬性配合物に上記原料に重量比１〜
８％のセメント成分中のカルシウム溶解度を高める金属
塩を添加してなることを特徴とするものである。That is, the autoclave cement composition of this invention is
The blending ratio of cement: silica: blast furnace slag is 6:3:1 ~
A hydraulic formulation of 3:3:4 with a weight ratio of 1 to 1 to the above raw materials.
It is characterized by the addition of a metal salt that increases the solubility of calcium in 8% of the cement component.
この発明において、使用されるセメント、及びシリカは
、従来周知のオートクレーブ用の配合材料が使用され、
スラグとして高炉スラグが使用される。In this invention, the cement and silica used are conventionally known compounded materials for autoclaves,
Blast furnace slag is used as the slag.

グの添加量を少なくすると、廃棄物の有効利用を図る本
発明の目的が達成されず、また、後者の割合よりスラグ
を多くすると、スラグの添加による強度低下が顕著とな
るからである。The blending ratio of these cement, silica and blast furnace slag is 6
:3:1 to 3:3:4 is because if the amount of slag added is less than the former ratio, the purpose of the present invention, which is to effectively utilize waste, will not be achieved. This is because when the amount of slag is increased, the strength decreases significantly due to the addition of slag.
この発明において、上記範囲の配合物に対して、セメン

のは、セメント、シリカ及びスラグのそれぞれの活性化

ントマトリックスの結合強度を高めるためであり、塩化
バリウム、あるいは塩化カルシウムが用いられる。In this invention, the addition of a metal salt that increases the solubility of calcium in the cement component to the formulation within the above range is intended to activate each of the cement, silica, and slag, and to reduce the strength loss caused by the addition of slag. Barium chloride or calcium chloride is used to increase the bonding strength of the cement matrix.
これらの金属塩の添加量を１〜８重量％とするのは、１
重量％より少ないと、添加の効果が無く、８重量％より
多いとエフロレッセンスの発生等不都合が生じるからで
ある。The amount of these metal salts to be added is 1 to 8% by weight.
If it is less than 8% by weight, the addition has no effect, and if it is more than 8% by weight, problems such as efflorescence may occur.
上記配合物を他の補強繊維、骨材等、及び水と混合し、
賦形体とし、オートクレーブ養生した場合、上記金属塩
の作用により反応が活性化され、高強度の製品が得られ
る。Mixing the above compound with other reinforcing fibers, aggregates, etc., and water,
When it is made into an excipient and cured in an autoclave, the reaction is activated by the action of the metal salt, resulting in a product with high strength.
