〔産業上の利用分野〕
この発明は軽量無機質製品の製造方法に関し、詳しくは
、無機質軽量発泡骨材を添加した常法配合における軽量
無機質製品の製造方法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing lightweight inorganic products, and more particularly, to an improvement in the method for producing lightweight inorganic products in a conventional blending process in which inorganic lightweight foamed aggregate is added.
従来、無機質建材の軽量化をはかるため、セメント、珪
砂よりなるセメント配合物にパーライト、プラスバルー
ン等の無機質軽量発泡骨材を添加し、この添加物により
軽量化を達成することが種々行われている。Conventionally, in order to reduce the weight of inorganic building materials, various attempts have been made to add inorganic lightweight foamed aggregates such as perlite and plus balloons to cement mixtures consisting of cement and silica sand, and to achieve weight reduction with these additives. There is.
ところで、上記無機質軽量発泡骨材は添加すればするほ
ど軽量化は促進されるがこれと共に強度の低下も生し、
やがては建材として実用出来ない程度にまで強度が低下
する欠点があった。By the way, the more the above-mentioned inorganic lightweight foamed aggregate is added, the more weight reduction is promoted, but along with this, the strength also decreases.
The drawback was that the strength eventually decreased to the point where it could no longer be used as a building material.
従って、無機質建材における強度と軽量化は相反する関
係となり、建材の用途に応し何れかを犠牲としなければ
ならない問題があった。Therefore, strength and weight reduction in inorganic building materials have a contradictory relationship, and there has been a problem that one or the other must be sacrificed depending on the use of the building material.
（発明が解決しようとする課題〕
この発明は上記問題に鑑み、軽量化が達成できると同時
に強度の低下も防止し得る軽量無機質製品の製造方法を
提供することを目的としてなされたものである。(Problems to be Solved by the Invention) In view of the above problems, the present invention has been made for the purpose of providing a method for manufacturing a lightweight inorganic product that can achieve weight reduction and at the same time prevent a decrease in strength.
即ち、この発明の軽量無機質製品の製造方法はセメント

において、無機質軽量発泡骨材の添加量の内そのｌ／４
〜１／２量をかさ比重０．５以下のフライアッシュに置
換することを特徴とするものである。That is, in the method for producing a lightweight inorganic product of the present invention, the blending ratio of cement and silica sand is approximately 1:1, and the necessary reinforcing fibers and fillers are added to this, as well as an inorganic lightweight foamed aggregate. In the cement formulation of lightweight inorganic products using the conventional method, 1/4 of the amount of inorganic lightweight foamed aggregate added.
It is characterized in that ~1/2 of the amount is replaced with fly ash having a bulk specific gravity of 0.5 or less.
この発明において前提とするセメント配合そのものは従
来常法により実施されているものでこの点に特徴は無い
。The cement mixture itself, which is the premise of this invention, has been conventionally carried out by conventional methods and is not unique in this respect.
この発明において、軽量化に使用する無機質軽量発泡骨
材としてはパーライト、シラスバルーン等の天然発泡軽
量骨材の他、人工軽量発泡骨材がある。In this invention, inorganic lightweight foamed aggregates used for weight reduction include natural foamed lightweight aggregates such as perlite and shirasu balloons, as well as artificial lightweight foamed aggregates.
この発明において、軽量発泡骨材の添加量において、そ
の添加量の１／４〜１／２をかさ比重０．５以下のフラ
イアッシュに置換する。In this invention, 1/4 to 1/2 of the amount of lightweight foamed aggregate added is replaced with fly ash having a bulk specific gravity of 0.5 or less.
このフライアッシュは５ｉ（ｈの他ＣａＯも多量に含む
ため反応性が高く、従ってパーライト等の粒径の大きい
発泡骨材の間隙においてセメント粒子と良く反応し発泡
骨材を取り囲む状態で強固なマトリックスを形成する。This fly ash has high reactivity because it contains a large amount of CaO in addition to 5i (h), so it reacts well with cement particles in the gaps between foamed aggregates with large particle sizes such as perlite, and forms a strong matrix surrounding the foamed aggregates. form.
一方、このフライアッシュとしてかさ比″１０．５以下
のものを用いれば、製品全体の軽量化にも寄与する。On the other hand, if a fly ash with a bulk ratio of 10.5 or less is used, it also contributes to reducing the weight of the entire product.
この発明においてフライアッシュを軽量発泡骨材の添加
量の１／４〜１／２Ｍ換するのは、１／４より少ない置
換量の場合は十分な建材強度が得られないからであり、
また１／２より多い置換量の場合はフライアッシュの水
和反応で生しる水和物質により返ってセメントマトリッ
クスの強度が損なわれるからである。In this invention, the reason why fly ash is replaced by 1/4 to 1/2 M of the added amount of lightweight foamed aggregate is because if the replacement amount is less than 1/4, sufficient strength of the building material cannot be obtained.
Moreover, if the amount of substitution is more than 1/2, the strength of the cement matrix will be impaired due to hydrated substances produced by the hydration reaction of fly ash.
次にこの発明の詳細な説明する。 Next, this invention will be explained in detail.
軽量発泡骨材としてかさ比重０．２１のパーライトを、
またシリカ源としてかさ比重０．３７のフライアッシュ
を用意し、表１の配合として厚さ５Ｎ縦横３００１の試
験片を賦形し、オートクレーブにて養生した。Perlite with a bulk specific gravity of 0.21 is used as a lightweight foam aggregate.
In addition, fly ash with a bulk specific gravity of 0.37 was prepared as a silica source, and a test piece with a thickness of 5N and 3001 mm in length and width was shaped using the formulation shown in Table 1, and was cured in an autoclave.
試験片について比重及び強度試験を行ったところ表１下
欄に示す結果となった。When specific gravity and strength tests were conducted on the test pieces, the results were shown in the lower column of Table 1.
表 １
骨材を使用して軽量無機質製品を製造する場合において

量％を示す。Table 1: When manufacturing lightweight inorganic products using aggregate, the reaction characteristics of fly ash can be used to increase the strength of the product without sacrificing the weight reduction of pearlite.The numbers in the formulation table indicate weight percent.

表１より明らかなように、本願発明による場合、比重が

比較例１に比べ強度が向上しているのが確認された。The unit of bending strength is kg/cj. As is clear from Table 1, in the case of the present invention, even though the specific gravity is 1.02, the strength is improved compared to Comparative Example 1, which has a specific gravity of 1.02. It was confirmed that
また比較例２．３より明らかなように比重に比し本願発
