Description
【発明の詳細な説明】 本発明は軽量骨材とその製造方法に関する。[Detailed description of the invention] The present invention relates to a lightweight aggregate and a method for producing the same.
発泡プラスチック（通称ステロポールなど）の出現以来
、これを活用した軽量断熱骨材の実用化のための、多角
的な研究が重ねられてきたのが未だ実用化には幾多の困
難があった。Since the advent of foamed plastics (commonly known as steropols, etc.), multifaceted research has been carried out to commercialize lightweight insulating aggregates using them, but there are still many difficulties in putting them into practical use.
すなわち、互いに異質的な発泡プラスチックとセメント
モルタルとを接合し混然一体とさせるに必要な接着剤（
合成または天然）は高価であるだけでなくこれを用いて
も大量生産に適合しない次のような製造上の難点が残る
欠点があった。In other words, the adhesive (
Synthetic or natural) is not only expensive, but even if it is used, it is not suitable for mass production and has the following manufacturing difficulties.
先ず、発泡プラスチックの表面が滑らかで表面に塗布さ
れる接着剤の分量が少なく、無機材質の細粒の表面は極
く薄く塗布されるに留まり接着剤が本来発現するべき弾
力性が欠除せざるを得ないため細粒表面の強度が低く、
養生（凝結、硬化）の途上または運搬中に骨材相互の摩
擦、衝撃により陪着剤層が破壊・剥離されることが多い
点である。First, the surface of the foamed plastic is smooth and the amount of adhesive applied to the surface is small, and the surface of the fine inorganic particles is only applied very thinly, lacking the elasticity that adhesive should originally exhibit. As a result, the strength of the fine grain surface is low,
The adhesive layer is often destroyed or peeled off due to friction and impact between the aggregates during curing (setting, hardening) or during transportation.
次に、上記の接着剤はセメントモルタルの施工時にセメ
ント粒子等をとり囲んでいるため、養生中セメントに対
する水分（Ｈ２Ｏ）と炭酸ガス（ＣＯ２）の浸透を遮断
してしまい、養生期間をいたずらに長びかせることであ
る。Secondly, since the above adhesive surrounds cement particles during cement mortar construction, it blocks moisture (H2O) and carbon dioxide (CO2) from penetrating into the cement during curing, which can unnecessarily shorten the curing period. It is about making it last longer.
さらに、養生期間中に接着剤自体の乾燥が著しい容積の
変化をもたらし、このことがセメントモルタルの収縮を
惹起させるためセメントが本来有すべき強度を脆弱化し
てしまうことが挙げられる。Furthermore, during the curing period, the adhesive itself dries, causing a significant change in volume, which causes the cement mortar to shrink, weakening the strength that cement should originally have.
以上の接着剤使用による難点を避けるため、接着剤を使
用せずに直接に発泡プラスチックを破砕させる破砕剤を
セメントモルタルと混合させる試みがなされているが、
この養生の期間中構造体に震動が加わると強度が著しく
弱くなるおそれがあった。In order to avoid the above problems caused by the use of adhesives, attempts have been made to mix crushing agents with cement mortar that can directly crush foamed plastic without using adhesives.
If the structure was subjected to vibrations during this curing period, there was a risk that the strength would be significantly weakened.
本発明は、上述のごとき強度上および製造上の難点を解

トモルタルを被覆硬化させた軽量骨材を製造する技術を
提供するものである。The present invention solves the above-mentioned strength and manufacturing difficulties, and solves the above-mentioned problems in terms of strength and manufacturing. , Takaneji) is first slurried to a consistency with good adhesive strength, i.e., in the state of kneaded clay, and then cement powder, calcium hydroxide, fine sand, and sodium silicate are sequentially mixed and stirred to form a paste-like clay or clay. The present invention provides a technology for manufacturing lightweight aggregate by coating a foamed plastic core material with a solid material, and then coating the surface with cement mortar and hardening it.

(OH)2, illites, etc. have the unique plasticity of clay due to the bonding forces in which atoms are in a balanced state of attraction and repulsion within the crystal lattice, i.e., ionic bonds, covalent bonds, metallic bonds, and van der Waals bonds. It exhibits adsorption properties, and the present invention takes full advantage of these properties of clay.

の表面に粘土層２が中間材を形成し、その表面にセメン
トモルタル層３が塗布されている。Figures 1 and 2 of the accompanying drawings show an example of a lightweight aggregate structure according to the present invention.
A clay layer 2 forms an intermediate material on the surface, and a cement mortar layer 3 is applied to the surface.
この場合、粘土層２とモルタル層３との間にモルタルが
粘土層に相互に浸透貫入し両者の親水性で浸透混合層４
が生成されて全体として結着力が強固になっている。In this case, between the clay layer 2 and the mortar layer 3, the mortar penetrates into the clay layer and penetrates into the clay layer, and due to the hydrophilic nature of both, the mortar penetrates into the clay layer 2 and the mortar layer 3.

である。As mentioned above, the present invention uses clays, which are easily available and have excellent strength as an adhesion mediating layer, as the main component of the adhesive, without using natural or synthetic adhesives, to obtain a good lightweight aggregate. It makes it possible to mass-produce building materials or structural materials for civil engineering at low cost, and its social contribution is significant.
