Description
【発明の詳細な説明】 (産業上の利用分野) 本発明は、高強度水硬性物質に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to high strength hydraulic materials.
セメント等の水硬性物質の強度を増す場合、従来にあっ
てはシリカヒユーム等のシリカ微粉や高性能減水剤を添
加することで目的を達成していた。In the past, when increasing the strength of hydraulic substances such as cement, the objective was achieved by adding fine silica powder such as silica hume or high performance water reducing agents.
(発明が解決しようとする課題)
しかしながら、上述のシリカ微粉は添加量がある程度多
くないと増強効果が得られず、添加量が増えた分セメン
トの流動性も同時に低下してしまう。そのため、従来に
あっては水を多量に添加してセメントの流動性を保持し
、作業効率を低下させないようにしているが、コンクリ
ートの強度を保つためには減水剤も多量に使用しなけれ
ばならないといった問題があった。(Problem to be Solved by the Invention) However, the above-mentioned fine silica powder cannot produce an reinforcing effect unless the amount added is a certain amount, and the fluidity of the cement decreases at the same time as the amount added increases. Conventionally, large amounts of water are added to maintain the fluidity of cement and prevent work efficiency from decreasing, but in order to maintain the strength of concrete, large amounts of water reducing agents must also be used. There was a problem that it didn't work.
そこで、本発明の技術的課題は、水硬性物質は対する増
強剤の添加量を少なくしても所定の強度向上が図れるよ
うにすると共に、水および減水剤の添加量も同時に少な
くする点にある。Therefore, the technical problem of the present invention is to make it possible to achieve a specified strength improvement even if the amount of a reinforcing agent added to a hydraulic substance is reduced, and at the same time to reduce the amount of water and water reducing agent added. .
(課題を解決するための手段)
本発明は上記技術的課題を解決するために、水硬性物質
100重量部に対して、金属シリコン粉末0.01重量
部以上が添加混合されてなる高強度水硬性物質を手段と
している。(Means for Solving the Problems) In order to solve the above-mentioned technical problems, the present invention provides high-strength water containing 0.01 parts by weight or more of metal silicon powder added to 100 parts by weight of a hydraulic substance. Hard substances are used as means.
ここで、水硬性物質とはその一部又は全部が、普通セメ
ント、石膏、早強セメント、超早強セメント、混合セメ
ント、中庸熱セメント、アルミナセメント及び高炉セメ
ントから選ばれたうちの少なくとも一種である。Here, the hydraulic substance is at least one selected from ordinary cement, gypsum, early strength cement, ultra early strength cement, mixed cement, moderate heat cement, alumina cement, and blast furnace cement, in part or in whole. be.
また、金属シリコン粉末とはその一部又は全部が、フェ
ロシリコン、金属シリコンとアルくニウムとの合金など
金属シリコンを含む合金から選ばれたうちの少なくとも
一種である。Further, a part or all of the metal silicon powder is at least one selected from alloys containing metal silicon, such as ferrosilicon and alloys of metal silicon and aluminium.
また、金属シリコン粉末の添加量は、水硬性物質100
重量部に対してo、oi重量部以上で増強効果があり、
30重量部で最大の効果を宥する。In addition, the amount of metal silicon powder added is 100% of the hydraulic material.
It has a reinforcing effect when it is more than o or oi parts by weight,
The maximum effect is achieved at 30 parts by weight.
上記金属シリコン粉末は疎水性であるため、水硬性物質
と混合した場合、一定の流動性を確保するのに必要とな
る水の量が水硬性物質単独の場合より少なくて済み、従
来のように高性能減水剤を多量に使用する必要がなくな
る。Since the metal silicon powder mentioned above is hydrophobic, when mixed with a hydraulic substance, the amount of water required to ensure a certain level of fluidity is smaller than when using the hydraulic substance alone, and it is not necessary to mix it with a hydraulic substance. There is no need to use large amounts of high performance water reducing agents.
このように、本発明では水硬性物質に金属シリコン粉末
を添加し均一に混合することにより、金属シリコンが水
硬性物質の刺激を受けてシリカとなり、このシリカが水
硬性物質の硬化後における水の抜けた部分を補充して緻
密な構造を形成し高強度化していく。In this way, in the present invention, by adding metal silicon powder to a hydraulic substance and mixing it uniformly, the metal silicon is stimulated by the hydraulic substance and turns into silica, and this silica becomes a part of the water after the hydraulic substance hardens. The missing parts are replenished to form a dense structure and increase its strength.
(実施例)
水硬性物質に普通セメントを用い、これに金属シリコン
粉末(99%シリコンを600メツシユに粉砕したもの
〉を種々の割合で添加したのちJISモルタルを成形し
、各成形体の圧縮強度及び曲げ強度を比較した。(Example) Ordinary cement was used as the hydraulic substance, metal silicon powder (99% silicon pulverized into 600 meshes) was added in various proportions, and JIS mortar was formed, and the compressive strength of each molded body was determined. and bending strength were compared.
JISモルタルの成形条件を表−1に、強度試験の結果
を表−2にそれぞれ示す。The molding conditions of the JIS mortar are shown in Table 1, and the results of the strength test are shown in Table 2.
表−2

以上説明したように、本発明に係る高強度水硬性物質に
よれば、金属シリコン粉末を添加混合することにより、
セメントなどの水硬性物質の強度向上が図られるととも

、従来のように減水剤を多量に使用する必要がないとい
った効果がある。Table 2 (Effects) As explained above, according to the high-strength hydraulic material according to the present invention, by adding and mixing metal silicon powder,
In addition to improving the strength of hydraulic substances such as cement, fluidity can be obtained without increasing the amount of water added, so there is no need to use large amounts of water reducing agents as in the past.
この試験結果から、普通セメントだけの場合と、これに
金属シリコン粉末を添加した場合とを比較すると、圧縮
強度及び曲げ強度とも添加した方が強度が大きくなって
いる。また、金属シリコン粉末の添加量の違いによる強
度の比較では、30重量%までは圧縮強度及び曲げ強度
とも次第に大きくなり、40重量%になると強度がやや
低下する。From this test result, when comparing the case where only ordinary cement is used and the case where metallic silicon powder is added to this, the strength is higher when both compressive strength and bending strength are added. Further, when comparing the strength depending on the amount of metal silicon powder added, both compressive strength and bending strength gradually increase up to 30% by weight, and the strength slightly decreases when it reaches 40% by weight.
