効性改良材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an immediate-acting soil improvement material for baseball grounds, athletic fields, tennis courts, stadiums, open spaces, and other grounds used for outdoor sports, recreation, athletic competitions, gatherings, and other purposes. It is something.
野球グラウンド等は雨あがシ、小雨時、冬期の鞘どけ、
雪どけ時にはグラウンドコンディションが極端に悪くな
る。Baseball grounds, etc. are covered with rain, during light rain, and during winter, they are removed from the sheaths.
When the snow melts, the ground conditions become extremely poor.
水だまり、ぬかるみ、軟弱個所が出来て使用することを
困難にしていた。Puddles, mud, and soft spots formed, making it difficult to use.
そのため、グラウンドの土を水は庁のよいものにする等
の改良が行われているものの、グラウンドコンディショ
ンは天候によって左右されていた。For this reason, although improvements were made to the ground, such as making the soil better for water, the condition of the ground was still dependent on the weather.
本発明はこれら水たまり、ぬかるみ、軟弱個所のあるコ
ンディションの悪いグラウンドの土壌に対して、瞬間的
な脱水能力を持つエトリンガイトの加熱脱水品を加える
ことによシ、グラウンドコンディションを改良する。The present invention improves the ground condition by adding a heated dehydrated product of ettringite, which has an instantaneous dehydration ability, to the soil in poor condition with puddles, mud, and soft spots.
本発明改良材の特色は次の点にある。The improved material of the present invention is characterized by the following points.
（１） 少量の使用でよい。(1) Only a small amount is required.
脱水エトリンガイトは自重の８５係の水と反応し、更に
粉粒体では自重の２００％以上もの水を固定化する能力
を持っている。少量の添加で、水たまり、ぬかるみ、軟
弱土を乾いた土に変える、
（２）手軽に短時間で土壌改良ができる。Dehydrated ettringite reacts with water that is 85 times its own weight, and in powder form, it has the ability to immobilize more than 200% of its own weight in water. By adding a small amount, you can turn puddles, muddy, and soft soil into dry soil. (2) You can easily improve soil in a short time.
大量の改良土の投入、整地等の大がかりな改良作業を必
要としないので、人手によって手軽に行える。Since it does not require large-scale improvement work such as inputting a large amount of improved soil or leveling the land, it can be easily performed by hand.
（３） 直ちに使用できる。(3) Can be used immediately.
脱水エトリンガイトの吸水作用は非常に速く、瞬間的で
あるのですぐ使用できる状態に改良できる。The water absorption action of dehydrated ettringite is very fast and instantaneous, so it can be improved to a ready-to-use state.
即ち、水たまり、ぬかるみ、軟弱個所に脱水エトリンガ
イトの粉粒体を散布、又は散布混合して土ならしする。That is, the soil is leveled by scattering or mixing powdered dehydrated ettringite on puddles, muddy areas, and soft areas.
場合によっては転圧、土の添加等コンディション延応じ
て調整する。In some cases, adjustments such as rolling compaction and addition of soil may be made depending on the prevailing conditions.
改良作業が終ると、すぐ使用できるようになる。Once the improvement work is complete, it will be ready for use immediately.
これらの点は従来の土壌改良材とは違うところである。These points are different from conventional soil improvement materials.
その結果、滑る。走りづらい、動きにくい。As a result, it slips. Difficult to run or move.
汚れる。ボールが不規則な動きをする、といったグラウ
ンドコンディションの悪さに伴う欠点が解消される。Get dirty. This eliminates the drawbacks associated with poor ground conditions, such as the irregular movement of the ball.
また、小雨の中、雨あがり、冬期の霜どけ雪どけ、とい
ったグラウンドコンディションの悪い条件でも本改良材
を使用することによシ、直ちにグラウンドを改良するこ
とが可能である。In addition, by using this improvement material, it is possible to immediately improve the ground even when the ground condition is poor, such as in light rain, after rain, or after melting frost or snow in winter.
（４） 安全である。(4) It is safe.
アルカリ物質ではないので誤って目に入つたり、皮ふに
付着しても炎症を起す恐れがない。Since it is not an alkaline substance, there is no risk of irritation if it accidentally gets into your eyes or adheres to your skin.
水によって著しく発熱するといった危険もないので安心
して使用できる。It can be used with confidence as there is no risk of significant heat generation due to water.
また、保存に際して特別の注意を払う必要もない。Further, there is no need to take any special precautions during storage.
エトリンガイトはＣ３Ａ φ３ＣａＳＯ４・３２Ｈ２０
の組成を持つ含水塩であり、これを加熱することによシ
、容易に脱水エトリンガイトを得ることができる。Ettringite is C3A φ3CaSO4・32H20
Dehydrated ettringite can be easily obtained by heating it.
エトリンガイトのｋｌｌｓＯｎをＦｅｚＯ２に置換した
化合物、固溶体であってもよい。It may also be a compound or solid solution in which kllsOn of ettringite is replaced with FezO2.
また脱水エトリンガイトを含んでいれば、他の物質との
混合物であっても差支えない。Further, as long as it contains dehydrated ettringite, it may be a mixture with other substances.
実施例
雨あがりの野球グラウンドに、約Ｉ Ｘ １．４メート
ルの水たまシ、および軟弱土のある不良個所がある。EXAMPLE A baseball field after rain had a water puddle measuring approximately I x 1.4 meters and a defective area with soft soil.
これに対して、約１．４ Ｋｙの脱水エトリンガイト粉
粒体を散布した。On the other hand, about 1.4 Ky of dehydrated ettringite powder was sprayed.
次いで、熊手状の歯を持つトンｙｌ？（ＴＷ木製の土な
らし用具）でかきまぜ、土ならしを行った。Next, a tonyl with rake-shaped teeth? (TW wooden soil leveling tool) was used to stir and level the soil.
さらに、土踏みを行うと、水たまり、軟弱土が改良され
て、他の乾燥状態にある部分とほとんど同じ状態になっ
た。所要時間は約２分である。Furthermore, when soil treading was carried out, the puddles and soft soil were improved and became almost the same as other dry areas. The time required is approximately 2 minutes.
使用した脱水エトリンガイトは、白石工業社製のサチジ
ホワイトを乾燥し、７ミリメードル以下に粗砕して電気
炉で焼成した。The dehydrated ettringite used was dried Sachiji White manufactured by Shiraishi Kogyo Co., Ltd., crushed into pieces of 7 mm or less, and fired in an electric furnace.
焼成＠度は、３００℃で１時間保持した。The firing temperature was maintained at 300° C. for 1 hour.
