Description
【発明の詳細な説明】 ［発明の技術分野］ 本発明は放射線遮断用、遮音用にコンクリートに係る。[Detailed description of the invention] [Technical field of invention] The present invention relates to concrete for radiation shielding and sound insulation.
［発明の技術的背景とその問題点］
放射線や音響の遮断はコンクリート壁によってなされる
ことが多い。而して、その遮断能力は重量、すなわち壁
の厚さおよびコンクリートの密度に関係するものと考え
られている。[Technical background of the invention and its problems] Radiation and sound are often blocked by concrete walls. It is therefore believed that the blocking capacity is related to the weight, ie the thickness of the wall and the density of the concrete.
従って、建造物の強度上、耐久性上必要なコンクリート
の密度、壁の厚さよりも大きな密度、厚さとすることと
なる。Therefore, the density and thickness of concrete must be greater than the density and wall thickness of concrete necessary for the strength and durability of the building.
放射線遮断や遮音に必要とは言え、コンクリートを多く
消費し、経済的には不利である。Although it is necessary for radiation shielding and sound insulation, it consumes a lot of concrete and is economically disadvantageous.
［発明の目的］ 本発明は上記の事情に基づきなされたもので。[Purpose of the invention] The present invention has been made based on the above circumstances.
薄くコンパクトな壁で十分に放射線、音響を遮断し得る
放射線、音響遮断用のコンクリートを提供する。To provide radiation and sound shielding concrete capable of sufficiently shielding radiation and sound with a thin and compact wall.
［発明の概要］
本発明の放射線遮断用、遮音用コンクリートは、セメン
ト、砂、粉末状粒子状または繊維チップ状の鉛、水を混
練しこれを養生硬化してなることを特徴とする。[Summary of the Invention] The concrete for radiation shielding and sound insulation of the present invention is characterized in that it is made by kneading cement, sand, lead in the form of powdery particles or fiber chips, and water, and curing and hardening the mixture.
［発明の実施例］
本発明の放射線遮断用、遮音用コンクリートはセメント
、砂、粉末粒子または繊維チップ状の鉛、水を混練し、
加圧脱水、成形するか、型枠に振動を加えながらまたは
振動を加えないで型枠中に流し込み養生硬化させて所要
の形状の製品とする。[Embodiments of the Invention] The concrete for radiation shielding and sound insulation of the present invention is made by kneading cement, sand, lead in the form of powder particles or fiber chips, and water.
The product is dehydrated under pressure and molded, or poured into a mold with or without vibration and allowed to cure and harden to form a product into the desired shape.
鉛は比較的密度が高く、放射線や音響を遮断する能力が
あることは周知である。よって本発明のコンクリートに
よって構成した壁は、薄くコンパクトであっても放射線
遮断能力、遮音能力に優れている。It is well known that lead is relatively dense and has the ability to block radiation and sound. Therefore, even if the wall made of the concrete of the present invention is thin and compact, it has excellent radiation blocking ability and sound insulation ability.
以下に、本発明のコンクリートの用途について説明する
。The uses of the concrete of the present invention will be explained below.
１、壁材またはフロアタイル
強度上、耐久性上必要な厚さで十分な遮音をすることが
できる。また、体積当たりの重量が大きいため、音の共
鳴を防ぐことができる。1. Sufficient sound insulation can be achieved with the thickness of the wall material or floor tile required for strength and durability. Furthermore, since the weight per volume is large, it is possible to prevent sound resonance.
２、放射性廃棄物処理容器
ドラム缶のライニングに本発明のコンクリートを使用す

明のコンクリートを流し入れ、遠心力により缶内面に均
一に付着させ硬化させる。ライニングは缶内面の腐食を
防ぎ、放射線の透過を防止する。また、本発明のコンク
リートは鉛が混入されているため、ライニングの厚さは
最小限でよく、ドラム缶の廃棄物収容能力が大きく減少
させられることはない。2. The concrete of the present invention is used for lining drums of radioactive waste treatment containers. That is, the concrete of the present invention is poured into each drum by rotating at high speed, and is uniformly adhered to the inner surface of the can by centrifugal force and hardened. The lining prevents corrosion on the inside of the can and prevents radiation from passing through. Also, since the concrete of the present invention is lead-laced, the lining thickness can be kept to a minimum and the waste storage capacity of the drum is not significantly reduced.
