Abstract
Description
本発明は、各種スラグ（例えば、溶融スラグや高炉スラグ等）に火山噴出物（シラス）を表面コーティングし、その粒材を、バインダーにセメントを使用し成型加工したポーラスコンクリート製品を製造する方法に関するものである。 The present invention relates to a method for producing a porous concrete product obtained by surface-coating volcanic ejecta (shirasu) on various slags (for example, molten slag, blast furnace slag, etc.) and molding the granule using cement as a binder. Is.
砂、砕石、セメント等を加工したポーラスコンクリートは多く出来ている。だが、従来品は、透水性は有るが保水性は少ない。又、シラスとセメントを混ぜ合わせたシラスコンクリートも出来ているが、透水性や保水性の有る物はない。 A lot of porous concrete made from sand, crushed stone, cement, etc. is made. However, conventional products have water permeability but low water retention. Shirasu concrete is also made by mixing shirasu and cement, but there is no water-permeable or water-retaining material.
従来のスラグ利用のポーラスコンクリートは、一般的な砂、砕石、セメントの中にスラグを少し含有させた物（特許文献１）やスラグを混和材料として利用する物（特許文献２）がある。 Conventional slag-based porous concrete includes a material in which slag is slightly contained in general sand, crushed stone, and cement (Patent Document 1) and a material that uses slag as an admixture (Patent Document 2).
本発明の様にスラグの粒状物にシラスをコーティングして細骨材とし、粗骨材と細骨材を加えセメントをバインダーとし成型加工するポーラスコンクリートは出来ていない。 As in the present invention, a porous concrete is not formed by coating slag on a granular material of slag to form a fine aggregate, adding coarse aggregate and fine aggregate, and using cement as a binder.
火山噴出物であるシラスはあまり有効利用がなされていない。又、各種スラグは産業廃棄物として扱われる中、近年になって土木資材として路盤材などに利用され始められているが、いまだ未利用物が多い。 Shirasu, which is a volcanic eruption, has not been used effectively. In addition, various slags are being used as roadside materials as civil engineering materials in recent years while being treated as industrial waste, but there are still many unused materials.
本発明は火山噴出物（シラス）と各種スラグの有効利用問題を解決することに鋭意研究し、シラスの保水力に着目した。その結果、スラグの粒状物にシラスをコーティングすることで、透水性と保水性の両特徴を持ったポーラスコンクリートを発明し上記課題を多大に有効利用することに成功した。 The present invention has eagerly studied to solve the problem of effective use of volcanic ejecta (shirasu) and various slags, and has focused on the water retention capacity of shirasu. As a result, by coating the slag particulates with shirasu, we have invented porous concrete having both water permeability and water retention characteristics and succeeded in effectively utilizing the above-mentioned problems.
火山噴火物（シラス）は一般的に含水率が自重比４０％〜５０％ほどあるので、乾燥させて含水率を１０％以内に加工する。その含水率１０％以内のシラスを樹脂セメント等によりスラグ粒状物にコーティングすることで保水力の有るポーラスコンクリートの基材が出来ることを特徴とする。 Since volcanic eruptions (shirasu) generally have a moisture content of about 40% to 50% by weight, they are dried and processed to a moisture content within 10%. It is characterized in that a porous concrete base material having water retaining ability can be formed by coating a slag having a water content of 10% or less on a slag granular material with resin cement or the like.
シラスコーティングスラグ粒状物を基材とし、シラス細骨材を加えセメントをバインダーとして混練することで、高い透水性、保水性を得るシラススラグポーラスコンクリートが製造できる。 Shirasu slag porous concrete having high water permeability and water retention can be produced by using shirasu-coated slag granules as a base material, adding shirasu fine aggregate, and kneading cement as a binder.
本発明のシラスコーティングスラグ基材を混練するバインダーはセメントを使用するが、その混練用セメントは特に限定されず、普通のセメント、高炉セメント、樹脂セメント、アルミナセメントなどを使用できる。 Cement is used as the binder for kneading the shirasu coating slag substrate of the present invention, but the cement for kneading is not particularly limited, and ordinary cement, blast furnace cement, resin cement, alumina cement and the like can be used.
本発明のシラススラグポーラスコンクリートはスラグに含まれる重金属等の溶出を樹脂セメントとシラスでコーティングすることにより、安全安定した基材として利用できることも特徴である。 The Shirasu slag porous concrete of the present invention is also characterized in that it can be used as a safe and stable base material by coating elution of heavy metals contained in the slag with resin cement and Shirasu.
本発明のシラススラグポーラスコンクリートはシラスの有効利用とスラグを安全安定基材として利用し、安価で高い保水性と透水性を得られるポーラスコンクリートが製造でき、各種多方面に活用できる利点がある。 The Shirasu slag porous concrete of the present invention has an advantage that it can be used in various fields because it can be used effectively and the slag can be used as a safe and stable base material to produce porous concrete that is inexpensive and has high water retention and water permeability.
安全で安価な多方面に活用できるポーラスコンクリートを製造できることを実現した。 We have realized that it is possible to manufacture porous concrete that can be used safely and inexpensively in various fields.
火山噴出物（シラス）を高温乾燥により含水率１０％以内のシラスに変え、その乾燥シラスを樹脂セメント等でスラグ粒状物にまんべんなくコーティングして安全安定基材を得る。 The volcanic product (shirasu) is converted into a shirasu having a water content of 10% or less by high-temperature drying, and the dried shirasu is evenly coated with slag granular material with resin cement or the like to obtain a safe and stable substrate.
コーティングスラグを粒状の大きさにより中粒４ｍｍ〜７ｍｍと小粒１ｍｍ〜３ｍｍに２分類する。その中粒と小粒を１対１又は、３対２の割合で配合し、粗骨材とする。 The coating slag is classified into two types according to the size of the particles: medium grains 4 mm to 7 mm and small grains 1 mm to 3 mm. The medium grains and the small grains are blended at a ratio of 1: 1 or 3/2 to obtain a coarse aggregate.
該粗骨材とシラスとセメントを混練してポーラスコンクリートを得る。その配合比率は重量比粗骨材１７〜１８とセメント４〜５とシラス１で混練し水はセメント比Ｗ／Ｃ３０％〜３５％を使用する。 The coarse aggregate, shirasu and cement are kneaded to obtain porous concrete. The blending ratio is kneaded with coarse aggregates 17-18, cement 4-5, and shirasu 1 and the water uses a cement ratio W / C of 30% to 35%.
混練手順は、モルタルミキサーに粗骨材を投入し水を加える。３０秒以上撹拌した後、セメントを投入する。９０秒〜２分混練し、最後にシラスを投入し６０秒ほど撹拌、混練する。 In the kneading procedure, coarse aggregate is put into a mortar mixer and water is added. After stirring for 30 seconds or more, cement is added. Kneading is performed for 90 seconds to 2 minutes, and finally Shirasu is added and stirred and kneaded for about 60 seconds.
撹拌、混練された材料を用途に合わせた金型にすばやく入れ押圧し、その金型のまま養生し２４時間後に脱型する。 The agitated and kneaded material is quickly put into a mold suitable for the application, pressed, cured as it is, and demolded after 24 hours.
脱型して２０日間養生すれば保水性の高い透水性ポーラスコンクリート製品が出来上がる。 After demolding and curing for 20 days, a highly water permeable porous concrete product is completed.
本発明はスラグ粒状物に樹脂セメント等で微粒子シラスをコーティングし安全安定した粗骨材を製造でき、廃棄物スラグを有効利用できると共に、火山噴出物（シラス）も利用できる。 The present invention can produce a stable and stable coarse aggregate by coating fine particles of slag with resin cement or the like on a slag granule, and can effectively use waste slag as well as volcanic eruptions (shirasu).
保水性の高い透水性ポーラスコンクリート製品は今後要望の高いインターロッキングや漁礁、地下貯留槽など、用途は多岐にわたる。 Highly water permeable porous concrete products have a wide range of uses, such as interlocking, fishing reefs, and underground storage tanks, which are highly requested in the future.
火山噴出物（シラス）や各種スラグは資源として大量に存在し、原料コストが安く、保水性の高い透水性ポーラスコンクリート製品が安価で提供できる。 Volcanic ejecta (shirasu) and various slags exist in large quantities as resources, and raw material costs are low, and water-permeable porous concrete products with high water retention can be provided at low cost.
当該方法で製造された製品は廃棄物スラグを再利用できた商品としてグリーン認定の適用を受けることができる。 Products manufactured by this method can be applied for green certification as products that can reuse waste slag.
